How bad is my gas stove?

We have found “tri-ply” stainless steel pans work really well, better than on gas. Cast iron is also brilliant, I inherited loads of them. We have aluminium none stick frying pans with solid stainless steel bases, they work well.
Aluminium pans without a solid steel base are absolutely crap on induction - even the ones that say they work. Avoid them.
If you have any pans with a slightly curved base they won’t work. And you will have to get a Wok with a flat bottom designed specifically for induction.
Make sure you read reviews before you purchase any new pans, and if you are changing your hob to an induction one be prepared for replacing your pans - budget to spend more on them than the hob even.
We are absolutely converted to induction, love it and will never go back. Planning to one day get rid of the gas boiler too.
On gas we have a wok ring that just sits on top of the burner.
You would need to get a special flat bottom Wok designed for induction. I believe there are also some induction woks that come with a special plate or ring you place them on to make them work and still have a curved bottom, I have no experience of them.
Alternatively maybe it’s just relying on inducting directly to the Wok bottom but the surface area touching the glass plate is very small so I can’t see it working well.
The ring does three things (probably). Keeps the wok supported, transfers heat to the pan, and tricks the sensors in the stove into thinking there's a flat pan on it.
This has sort of been my experience with induction beyond woks too, it often requires technique and equipment concessions. Great for boiling water and sautéing though. The tops also have durability/longevity issues when compared to gas and that isn’t usually acknowledged.
If it has a flat bottom, then it’s not a wok.
Personally, I hate cooking on induction. My parent have it and it never worked for me. I need to see/hear the gas to be able to control the heat properly.
Once they shut off the gas lines due to the energy transition, I’m going to run a gas pipe from the kitchen to my basement and just buy it in canisters.
I think there are probably still UX problems to be solved with Induction, the visual feedback on gas is better. We fortunately have knobs on ours (I hate the touch buttons on some).
This won't happen. What will happen instead is that the gas to cook your omelette in the morning will cost three times more than going to a restaurant would and you'll make your own decision about shutting down your gas lines.
This is the same thing I say to petrol heads about gas. Sure, there might be some left for enthusiasts. But enthusiasts alone will not be able to afford the massive economies of scale that make that consumption anything close to affordable.
> so it's very unlikely that synthetic Methane will cost more than a few dozen cents per kWh
No, it’ll cost much more than that. You’re ignoring the factored in cost of storing and distributing gas. This is something that’s only affordable because of economies of scale (and government support) because it was the only practical option for heating and hot water for a while. As electricity gets cheaper and people switch over to heat pumps and electric hot water heaters, the cost of that distribution network is going to fall on fewer people, driving up their cost.
I wouldn’t be surprised if that the gas bill for synthetic methane just for cooking was as high as your current gas bill for heating and cooking. Once economies of scale go away, things get costly fast.
> So you can run a stove for an hour a day for one or two bucks or so. I guess that's several times more than you pay for natural gas, but a lot cheaper than going to a restaurant.
Sure. But the competitor to a natural gas stove isn’t eating out, it’s electricity. Especially as gas gets more expensive and induction ranges become the norm.
Not sure where you live, but in my country the plan is to get everyone off gas by 2050. At that time the national gas network should be shut down.

It has a flat bottom "outside", inside it has the same shape as a normal wok.
A wok with a flat bottom outside and curved surface inside would also be heavy.
Yeah, it is heavy. You cant really toss things in it like you would a carbon steel wok.
If it’s heavy cast iron, it’s not a wok but a wadjan. Does it have 2 handles as well ? A wadjan is an Indonesian wok-like pan, but unlike a wok a wadjan retains heat due to it being heavy cast iron. A wok should be thin sheet steel so it heats up and cools down very quickly.
Wadjans are very good for things that have to stew/simmer, which is common in Indonesian cuisine. It has different uses than a Chinese wok.
Here is a link that might be more useful

Yeah, it isnt quite like a carbon steel wok but most people in North America wont have a a wok burner to hold the round bottom so they need the flat part.
You also definitely cant cook in them quite like a wok since as you say the cast iron holds so much heat. I usually just get it real hot on the burner for 5 or 6 minutes and then stir fry something. You have to take the food out when it is ready though because moving so much iron off the burner doesn't cool it down as quick.
A wok has 2 important features: it has a round bottom and it’s thin. The thin sheet steel allows it to heat up and cool down quickly. Maybe you can make a thick-bottomed pan that has a rounded bottom on the inside. And maybe you can pump enough energy in it to make it heat up quickly, but you can’t suck the energy back out. If it’s that massive it will not cool down quickly.
This is pretty much the case for all good induction kitchen-ware, since this is one of the main ways of cooking that induction allows that no other kitchen powersupply has.
Propane requires a slight modification to a gas hob (basically, different sized nozzles) but those came with my hob and it’s trivial to replace them.
Can you clarify, are you certain you're talking about induction? Inductive cooktops are a relatively recent trend, if you grew up with an electric range there's a good chance it was a resistive cooktop, not an inductive cooktop. Resistive cooktops are pretty notoriously unsatisfying.
Not that recent, at least not here in Europe. I know the difference, they had a resistive cooktop maybe 15 years ago or so, that was even worse, took forever to respond.
There are several problems with induction. While not inherent to induction, the controls tend to be crap. For some reason most induction cooktops have touch controls, which are an absolute disaster. At my parents previous place they had one where you had to first select the burner, and then use +/- touch buttons to change the temperature. You couldn’t quickly change anything. And of course the touch controls never worked if you had wet hands (and why would you have wet hands when cooking, right ?) Although indiction plates with knobs apparently do exist, I haven’t seen any yet.
A problem that is inherent is the complete lack of feedback: you can’t see a flame, you can’t hear it, meaning you can’t adjust the temperature by feel. Another inherent problem is that it limits the type of cookware you can use on it, only flat bottomed steel pans.
Basically, they are very impractical devices and not fit for purpose in any way.

It's one thing to have a preference, and another thing altogether to lie about the things you don't like to bolster your preference.
step back for a moment and realize that you're calling another human a bullshitter and a liar about their preference in cooking equipment. They're explaining their anecdotal position on the matter -- not teaching a college course.
I'm a big cook, i'm always in any cooking related thread on HN -- I never see the crowd rile up as much as when induction hobs are ever mentioned. It's strange to me that induction hobs create so much conflict and illicit so much passion from both sides of the aisle..
The damage feels like heat at lower frequencies (sitting in front of a fire oh no!) and a sizzle at higher frequencies (sitting in the sun oh no!). Induction stovetops emit orders of magnitude less than a fire and nothing at higher frequencies. Essentially: they get hot.
The best advice I can give: if you can't take the heat, get out of the kitchen.
https://www.cdc.gov/nceh/radiation/nonionizing_radiation.htm...
I think the article is precisely about studying more closely something that was thought to be safe (by the author at least), keeping an open mind never hurts :)
It's not like I would switch back to gas even if induction radiation was found to be causing some kind of health issue anyway, just like I'm still using my phone, because it's convenient (or going at the beach even if it's sunny because I like it ^^)
Definitely an electric oven though.
I’m now back on gas after a house move and I miss induction so much.
Hmm... My electric hob seems to control temperature by the amount of time the heating elements are active (+presumably a thermostat). There's a red light when the heating elements are active (or hot but switched off), and a definite click sound when the heating elements come on. You can see the heat immediately turn on when you change to a higher temp, and when you change to a lower temp it seems to just leave the application of heat off longer (I guess allowing elements to cool down to whatever the thermostat says they should be).
With a resistive hob (ceramic hob is the industry name) you’re relying on a large lump of stone (hence the name ceramic hob) to be a heat store and even out the elements lumpy power output. Problem with this approach is that it takes forever for the stone to heat up and cool down, so the hob is slow to respond.
With an induction hob, your heating pan directly with a electromagnetic field, the only thermal mass in the entire system is the pan. The hob can instantly change its power output, because its not relying on a stone to store energy, and thus has zero thermal mass.
So induction hob react at the speed of your pan, you have lightweight pan, then the pan temperature will change almost instantly. You got a heavy cast iron pan, then the pan will take a little longer to shed the extra heat.
FYI: If the hob glows when heating, it’s not induction. It’s a ceramic hob. Ceramic hobs are crap and give induction hobs a really bad name because the look the same when off. You can only tell if an induction hob is, if there’s a pan on top. They’re incapable of creating heat without a pan on top.
It absolutely does when the pulses are on the order of ten seconds long, as in many electric ranges. But yes, the thermal mass of the heated coil/cooktop are also a major factor.
In ceramic hobs, they usually don’t have proper power control systems. They normally rely on a set of thermal switches to disconnect the main heating element when the ceramic element gets hot enough. The entire control system is analog and relies physical phenomena like wax expansion etc. Phenomena that is well know to be unresponsive, but very cheap.
Induction doesn’t work by producing heat. It works by using electro magnets to excite the metal pots causing them to heat. This makes induction much more efficient than conventional electric (more efficient than gas too) but also fast to react to adjustments in heat settings because you’re not relying on conduction.
https://www.ukwhitegoods.co.uk/help/buying-advice/cooking-pr...
EDIT: from the link, a ceramic hob matches most closely
I still lift the pan to cool things a bit on an induction top; most units will give you 2 or 3 seconds before auto-off when you do so.
Why you may ask? My cheap induction hob has slowly failing membrane keys.
They are more easy to work with, IMO. Just get a good one.
https://www.samsung.com/nz/cooking-appliances/cooktops/induc...
Anecdotally, the gas feels slower. It seems to take an age to bring things up to the boil compared to my old induction.
Also, cleaning up after spills is a pain compared to a glass surface.
Stuff that isn't reactive can be well cleaned using ammonia vapor (which will break down grease and burned on grease and so on). Just put it in a bag or other container with some ammonia (no need to submerge, it's the vapor that does the work) and let it sit for a while.
High carbon steel pans (the kind used by kitchen services) have been brilliant. Every time I've seen an induction cooktop in use in a commercial service (for example, at my work place cafeteria at the "rice meal" station) they use high carbon steel pans.
The biggest problem: no cooking during power outages, which happen around 2-3x a year.
All our cast iron is Le Creuset.
I thought this was true (it makes some sense), but the data seems to show the opposite. This source has cast iron at 52 W/m-K, and 1% carbon steel at 43 W/m-K (0.5% carbon steel is at 54 W/m-K). Now, this obviously depends a lot on the processing and heat treatment of each material. But at the very least, the difference is not massive.
https://www.engineeringtoolbox.com/thermal-conductivity-meta...
I guess most of the reputation of cast iron comes from the chunky shapes of the pans, and that the higher end stainless cookware is often cladding around copper core
https://upload.wikimedia.org/wikipedia/commons/8/8a/Iron_car...
That’s interesting, can you compare the heat distribution problem to resistive? I have a gas range now, but when I had resistive I would preheat my cast iron in the oven for nice uniform heat distribution
Cast iron has never been quick on any type of stovetop.
I agree about carbon steel though. Underappreciated although gaining more attention.
Gas isn’t even remotely worth the downsides but there’s a number of dishes I can make that are easier and higher quality to do on gas, like if I’m trying to sear a large pan full of meat.
From physics point of view the way you raise temperature of pan has 0 effect on what's happening in the pan.
The only real solutions to this issue I could find are smaller and thicker pans, and the use of things like ovens and barbecues.
in a spherical cow sense, yeah, heat is heat. but the distribution of that heat is going to depend a lot on the implementation, and can make a big difference for searing meats or making delicate sauces.
radiant glasstops are really good at even heating, but only if the bottom of your pan is exactly the same size as the burner. the edge of the bottom ends up a little cooler, because energy is radiated out from the unheated sides, but not dramatically so.
I've found gas ranges to be pretty terrible for even heating. you get a hot ring where the most intense part of each flame touches the bottom, but a significantly cooler center. only the most expensive gas ranges come close to the evenness of a pedestrian glasstop. main benefit of these is you can effectively change the size of the burner, so nice if you have a lot of odd-sized pans.
I haven't had a chance to try an induction range myself, but I've read a lot of ymmv type posts on the internet. the gist seems to be that the tech itself is very good, but the outcome depends on the (electical) conductivity of the pan itself. which makes sense to me, at least in a handwavy sort of way. I wouldn't expect every pan to heat itself perfectly evenly in response to a uniform magnetic field.
I wish this type of functionality was more widely available. There is absolutely no need for devices like this to be expensive.
www.njori.com is a currently-vaporware device that looks potentially even better than the Control Freak and is substantially less expensive.
I bet the Breville cooktop is much better than mine, but you don't need to spend anywhere near that amount to get something decent.
They were as low as $1,000 over December.
They are amazing. I believe that eventually (maybe 10 years from now) you’ll be able to get a 4 burner stove top with the same features.
Essentially disposable nonstick pans (pay a small premium for induction compatibility).
Enameled cast iron Dutch ovens.
Very high end nitride-coated pans from Hestan, compatible with any induction stove except Hestan Cue.
Plain old cast iron.
Magnetic steel comals.
Carbon steel seasonable pans, paella pans, etc.
A flat-bottom wok.
All of those work on induction stoves, and all work on a device like the Control Freak. Just put them on and set a temperature.
On the other hand, the GE range has an app and buttons. Where’s the knob?
Currently I have two induction cooktops (counter top models, not built-in hobs) - one from Ikea and one Nuwave brand. The Ikea one looks pretty good, but it lacks precision. Looks like the Ikea one is no longer available in the US, but here it is on their AU website:
https://www.ikea.com/au/en/p/tillreda-portable-induction-hob...
The temperature settings go from 20 to 70 degree F increments. In particular, the jump from 210F to 280F really sucks. But it's great for boiling water, cooking pasta, etc.
The Nuwave induction cooktop I have allows 10 degree F increments, which is great for accurate precision. But it doesn't look very good in my opinion.
I'm also in the process of remodeling my kitchen and have a built-in Bertazzoni cooktop, which I've yet to unbox or install. I choose that because my wife wanted physical knobs instead of digital buttons and I agree that that does provide a nicer UI. I'm optimistic the knobs will provide precision temperature control.
Overall, I love cooking with induction - for control and clean air inside the house. However, one other issue I've struggled with is uneven temperature. Originally I thought cast iron would perform well, but it's not great with induction. I recently got some pretty decent stainless steel pots/pans from Tramontina, which are affordably priced compared Allclad, and those heat much more evenly. I also hope that when I install my built-in induction cooktop it will heat more evenly, perhaps with more magnetic rings.
I could never have that in my kitchen :(
If a crappy plug-in hob can boil water that quickly, it can cook that quickly too.
Next move I'm getting that sorted out - no more gas! (Mind you, companies are beginning trials here in the UK mixing Hydrogen with the gas supply, so there's a part of me that still wonders at the future benefit/end to end efficiency).
The future is in completely abandoning residential gas infrastructure, which will have immense benefits in allowing us to stop maintaining and expanding millions and millions of miles of leaky underground pipes. No amount of tweaking the mixture will change the fact that electricity is broadly useful for everything, and that gas is only useful for a small number of things that are quickly being overtaken by electricity.
Hell, if we had devices that could instantly summon sufficient quantities of water from thin air, I'd get rid of my water hookup, too, even though water lines aren't nearly as bad for the atmosphere as gas lines are.
All new builds and renovations should be encouraged to deploy full-electric.
- ed: Sorry, I should've specified - I meant 'in the UK' for the large amount of existing gas infrastructure.
Gas tankless water heaters are still sometimes a cost-efficient per-therm choice if you are already plumbed for gas [1] [2].
I've yet to find a calculator that figures the TCO (including costs that are externalized today, like pipe losses to the environment) between tankless water heaters using natural gas, propane, resistive electric, induction electric, and heat pump versions of those types, though. There are many different situations, so what is overall systemically efficient in one situation will not be suitable for another.
It would come as little surprise to most HN readers that I have a number of very expensive resistive air heaters that we call computers laying around for my work, so in my particular situation, a heat pump water heater works extremely well. However, I'm still unsure of the TCO after all the maintenance and repair is accounted for over the decades I will own the heat pump as it is undeniably more complex than more common water heaters. So I will give a nod to resistive water heaters as a likely good TCO choice in most situations after all costs are said and done [3].

Snideness aside, the fact that you have to concern yourself with what pans you buy for an induction stove is enough reason for many to not buy one. You can no longer buy any pan at a store, you must do your research first.
Throw out my current pans and buy even more expensive ones? You're not exactly selling me the induction here.
A cast iron pan at Wal-Mart is roughly the same price as a non-stick skillet and will outlast it by decades. Even if you don't want the Wal-Mart brand, you can buy Lodge, which is respected enough even by cast iron fanatics, and is cheaper even than mid range non stick or aluminum/steel skillets.
If one is willing to perform possible repairs, they can prevent tossing out the original embedded energy cost of manufacturing and delivering the original cast iron product (and many other items), which if one is so inclined, makes choosing the non-gas stove option and re-gearing for it (assuming they have say, only ceramic cookware) for ecological reasons as one decision factor an even more energy-thrifty choice.
We throw away an astonishing amount of goods that in past generations would be repaired, because we heavily externalize the costs of doing so, since we're such a poor civilization in Banks' The Culture sense. Like externalizing the pipeline leak costs of supporting the gas infrastructure that sits behind the gas stove.
Absolutely unmatched for boiling water, and I'm very happy using it with a cast iron dutch oven for slow cooking and soups or stews.
E.g. want to boil two pots of water in parallel? No can do - after warming up seemingly forever you will have one pot boiling for 5 seconds, then stopping and letting the other pot boil for five seconds, and so on.
I want to love induction - no gas pipes, so much easier to clean, so much better for air quality - but the regular stuff you can buy in stores just isn't there yet. Just the fact that they use a plug which can carry at most 3kW should be enough proof that you cannot use them for serious cooking.
Now, about your issue with parallel cooking: you indeed can not send Max Power to two pots if they are on the same rail. However, even the cheapest ranges I've ever seen have 4 burners, two rails. Which means you _could_ boil two pots of water, as long as you use the correct two burners. You learn pretty quickly which burners share a rail. I'd imagine the really nice ones have a transformer per burner so it's never an issue.
And as long as you're not trying to send boil-in-20-seconds kind of power, you can use all the burners without noticing anything.
We used to live in an apartment with single phase, there we had to somewhat limit the induction top to about 5,5kW and once again I practically never enocuntered it maxing out.
Then we moved to a house with an old electric stove. The pans turned to pure magic. More non-stick than our teflon pans.
Then we moved again to a place with an induction stove and bam: the pans are shit again.
It is obviously me, of course. Heat is heat. But something about induction makes me unable to use carbon steel.
Not tried a wok, yet, though.
Not only did we have a gas stove that was probably spiking NO2 levels when we actually used it; we also seemed to have a gas leak. It was not a big one, just a faint smell, but it was hard to pin down. A plumber concluded the connection between the range and the pipe wasn't the problem. No specific part of the range smelled stronger than the rest of it. For all we knew, it might be a hole in a pipe. So we wanted to make gas stop flowing through our unit (a condo within a three-family home, very normal here in Cambridge, Massachusetts) altogether.
We contacted an appliance company about switching to induction. To prepare, they told us, we would first need to upgrade the range power outlet to 40 amps, and cap off the gas pipe behind the range.
The electrical work cost $1800. It could have been much more; we were lucky our circuit breaker was positioned such that they only needed to make two openings in our walls. (They suggested we put little hatch doors in those spots to make future work easier.)
We asked our plumber to not only cap off the gas pipe behind the range, but also put in a valve in the basement, such that gas flow could be shut off to our unit, but also easily turned back on if a future owner wants to reverse what we did. We did this rather than turn off our gas altogether, because we have a gas water heater and still needed gas available there. The plumbing work cost about $300 I think.
To make cooking stay as close as possible to being how great and fast it is with gas, we chose a range with an induction stove: The LG LSE4616ST, which cost $3000.
We were lucky to be able to afford this change for our health. Of course, it would have cost a lot less if we hadn't cared about induction, but still multiple thousands of dollars.
We should be subsidizing conversions like this.
https://www.currys.co.uk/gbuk/household-appliances/cooking/h...
(Comparing BestBuy.com, where they are all fancy and start at $1000.)
Gas is dangerous, lines should be checked every couple of years (pressurized or vacuum tested) and the rubber connection hose for the range should be replaced every five years or so.
This is what we use for the final part of a gas line in the Netherlands.
No we shouldn't. Whatever you care about, like maybe CO₂, at those prices you can get a better bang for your buck elsewhere. For new installations it might make sense.
With gas it takes an hour.
Single burners are common for students and people with little room for anything larger, often very budget constrained.
Cooktops are often being put in as a part of an already expensive kitchen refit/build.
With that said, I'm sure there are other factors. Built-in hobs tend to need to be a lot thinner to fit in the available space, at least from what I have seen.
Also, at least in the US people have been told over and over how a kitchen remodel actually adds value to your house. "Every dollar you spend you get a dollar twenty back!" Well maybe so or maybe not, but if you don't sell your house before you need to remodel again, you are never realizing that gain.
Are you implying resistive coils, like Calrod, are more expensive, or not available?
Interestingly, there _is_ still a market for the halogen ones, even though induction units are about the same price on the low end: https://powercity.ie/groups/view?grp=45&class=41
Instead, They are practical. They have insane power (4.5kW is low range… and it goes directly into the pan…). They are easy to clean, and they have physical knobs: one for on/off, and a dial for power, which they display in a cheap display in kWs.
This is the epitome of the current green movement. Proponents want an unnecessary luxury green product subsidized for higher income households, even though there are perfectly fine substitutes that are just as good for the environment at 1/5 the cost you just described. I just can't get on board with a movement like this.
Just by nature of natural gas service existing you're being exposed to leaks by your municipality. It's better to be rid of it entirely. Washington DC, for example, has over 5,000 leaks. Boston leaks ~50,000 tons a year.
I suspect 50 years from now natural gas will be remembered as fondly as leaded gasoline is today.
That makes my regulatory capture spidey senses tingle in several different ways.
Subsidy in the form of a tax credit (so you need to front the government the money until tax season), so that you can buy something that basically only works if you own a house, into which you've already installed some infrastructure, itself subsidized via tax credit.
I can't help but think it would have been better to subsidize the purchase of used hybrids (or, you know, transit)
Overall I'm not against green subsidies. I'm against subsidies going to higher income households, it's government transfers to the rich! Especially in California, their green subsidies benefit the rich and hurt the poor.
The most efficient approach would be to correctly price the negative externalities of gas on health and environment, but pragmatically politicians understand that enormous carbon taxes are a very quick way to be voted out of office. Accordingly we arrive at the solutions available: subsidies for alternatives and/or a very slow phase in of carbon taxes.
Progressive jurisdictions are straight up banning gas hookups in new developments for environmental and health reasons.
For people using small burners in apartments, single ring plug in induction cooktops are available for about $100 with no other work required.
At least, I assume that is what they were talking about because there are no full scale induction ranges available for 300 pounds = $400. They start around $900.
There are two-burner countertop units on Amazon that use 120 volt/15 amp and are inexpensive. I have not tried them.
All this is of course fixed by installing a dedicated circuit for a real induction range. 220V * 40A increases the potential output six-fold, which is enough for any reasonable use case. But doing that is much more expensive, which is the whole of what I was trying to convey.
We're not not talking about 100% differences, we're talking closer to 400%. At least that's what I've found when measuring boil times for a 1200w plug in unit compared to a 15000btu gas burner.
Of course 240v is an absolute must for a 4 burner range, but that's not uncommon nor hard to get. Almost every home in the US has at least one 240v connection in the house, and it's usually $200-300 to get one installed. That's not nothing, but it's way less than it costs to install a gas line.
The number I cited came from some random website that I Google searched. If you have a more authoritative number, I'm happy to see a citation, but I won't be convinced by you just saying so. FWIW, the low power claims I made r.e. 2 burner plug in induction cooktops match my personal experience using them.
> Almost every home in the US has at least one 240v connection in the house, and it's usually $200-300 to get one installed.
I would be impressed if you could get 240 run from your breaker to your kitchen for $200, unless the breaker box is right next to your kitchen. The cost of the job is mostly going to depend on how time consuming it is to run the wires, assuming the wires already present are not sufficient for carrying 240v 40A. A brief search on the internet indicates a very wide range of quotes, probably dependent on site conditions and the local electrician labor market.
https://www.homedepot.com/p/Empava-36-in-Built-In-Electric-S...?
But you also need a 220+V and 40A circuit installed. How expensive this will be is 100% dependent on where your breaker box is in relation to your kitchen. Moreover, this option only works if your kitchen is already configured for a cooktop, as opposed to a full range. Most American kitchens are still configured for ranges, so to install something like this you'd also need to retrofit your cabinets. Now prices are starting to add up.
The minimum induction range is about $1000, so I don't think you're going to get away with spending less than $1500 except in a very exceptional case.
All that being said, yes, it can be done for much less than what OP paid in most cases, but I wouldn't necessarily count on the quality of the barebones induction range (at least based on my experience with portable induction cooktops -- they are often shit with small heating coils that produce intense hotspotting).
From googling around it looks like $300 to $800 in the US; I can't use homedepot here in the UK but I found this [0] for $350. That's ~$800 for an upgrade to a hob , assuming you do the electrical work.
> Most American kitchens are still configured for ranges, so to install something like this you'd also need to retrofit your cabinets. Now prices are starting to add up.
Anyone who owns a house with a range doesn't need a subsidy, to be frank. _houses_ might be, but apartments are likely using shitty bottom of the range gas burners, or crappy electrical coils. In my experience a £99 ikea portable induction burner was _way_ better than my builtin gas stove in my last rental apartment.

Yeah, but it doesn't have wifi. The one for $3000 is wifi enabled. Shame it doesn't have an LCD, means Doom is kinda of hard to run on it.
For less than 8 hours of work I'm sure.. I'm in the wrong profession.
It could be worse, try doing this in an old building in NYC.
Fortunately my brother in law is a licensed electrician and he'll do it for his normal rate, which won't include the 100+% markup from the business. I'll pay him generously and still end up paying less.
I have no doubt that gas causes more pollution but they are remiss for not mentioning the cooking process itself causes pollution.
The alternative ranges produce zero. Combustion heating, cooking and driving produces NO2, electric doesn't. The article is specifically about NO2, it has specific adverse health effects.
> Every time I cook the indoor air pollution also spikes "
What kind of pollution are you measuring? My air purifier reacts to frying too and shows "high pollution', but it just measures particles in the air - it cannot tell apart cancerous coal ash from harmless pollen and frying oil getting in the air.
Yes, and the real problem is vents that do not exhaust outside. Even in code crazy California, it is perfectly legal to have vents that just blow the air around.
I totally get the desire to switch to electric appliances for many reasons, but I am yet to meet an electric stove of any kind that I remotely enjoyed cooking on. Is this everyone's experience? Did I just not meet the right induction stove yet? Is there some sort of new technology on the horizon that will make electric stoves infinitely better?
A gas stove is a lot more powerful (10-60kW vs 1-3kW) but a lot of that heat simply escapes upwards.
Maybe this is specific to the stove they have though. I have and will continue to use gas because of this.
My parents have a different brand induction which does seem to have longer pulse cycles - maybe one every 5s or so. That is probably the effect you're describing - it'll go from essentially off to too hot and back. It's obviously a manufacture specific thing.
I use a 50s-era GM Frigidaire electric stove+oven and it doesn't modulate current to control temperature. It's quite a gas-like pleasure to cook with, prior to this I'd only ever experienced electrics like you're describing and they're awful.
And this is modulation of current - think of it as a very slow PWM.
But I must admit I have not disassembled the thing to understand its workings.
I don't even bother with heavy copper-clad pots and pans anymore, which were necessary before. This thing behaves like a gas stove.
So it's the heating element thermal inertia that differs, to smooth out the temperature?
Edit:
Looking at [0], what you're describing seems to be known as an "infinite switch".
That's not what the old stoves like mine has, this is just a rotary switch with 5 selectable presets. I assume it's changing the resistance.
Worth noting is also the even older Kalgoorlie [1] style stove, which changed the number of heating elements connected to regulate temperature.
This repair guide [2] describes both infinite and rotary switch controls on a high-level:
When the heating element is on, the heater inside the switch is on. The bimetal heats
(along with the element) until the contacts open. Then the bimetal cools (along with
the elements) until the contacts close again.
There are also fixed-temperature switches that vary the voltage going to the heating
elements to maintain fixed, pre-set temperatures. These are usually push-button or
rotary switches with fixed settings such as warm, low, medium and high.
In fixed-temperature switch controls, heat levels are varied by applying different
voltages (110V or 220V) to different coils of different resistances.

> I assume it's changing the resistance.
This isn’t feasible since you would need a resistor that was as big as the burner and essentially dropped as much heat as a stove element - for instance you would need a dummy load to dump as much waste heat as the burner itself to get a medium setting. In theory one could use a variac or multitap transformer - but again those would be relatively huge and heavy for the currents involved.
The GP was praising an induction hob, which is the third type.
Induction are very different from radiant electric and require cookware of particular materials. They are amazing in some respects and limited in others.
From a glance though both have smooth glassy surfaces that look modern.
The cheapest option apparently called a solid plate hob in Britain. Those coils are inside a ceramic (I think) plate. The cheapest ones cost about £80. They're difficult to damage, so you find them in the cheapest rented apartments (students etc): https://www.currys.co.uk/gbuk/household-appliances/cooking/h...
"Ceramic" hobs refers to the one with heating elements below glass/ceramic. Starts from £110, but it's a bit easier to damage. Many rented homes would have this, since it looks fancy and clean.: https://www.currys.co.uk/gbuk/household-appliances/cooking/h...
Induction hobs start at £180: https://www.currys.co.uk/gbuk/household-appliances/cooking/h...
Most ordinary (cheap or expensive) cookware sold in Europe is compatible with an induction hob, but not necessarily everything.
Gas stoves are great at bringing a pot of water to a boil. But they are not so good at very low heat, like leaving a covered pot to simmer. Most gas ranges don't go as low as I would like, and I need to watch the pot more carefully and stir more frequently than I would at home.
I'm sure most of my issues are familiarity. If I had spent my life cooking with gas, my techniques would have developed to work better with gas. But now that I'm set in my ways I will stick with electric.
edit: the boost is more powerful (3.7kW for the largest zone), but still. That's time limited (10 minutes or less), and limits the current to the other zone on the same phase.
The speed with which it heats things is actually kind of scary. I can take one of my 9" iron skillets from dead cold to smoking hot in under 20 seconds.
You regulate up or down in steps, and the controls sometimes have trouble recognizing your fingers if they are wet. There’s also no tactile feedback.
I’d much rather turn a knob.
Then it would be perfect.
When I looked for a new stove last year I tried to find one with induction AND knobs. I ended up getting a non-induction stove, with knobs, works well enough although I would swap it for one with induction and knobs any day, haha!
worse, i find myself trying to micro-optimize my use of oven temperature buttons: instead of holding up until the temperature is reached, i repeatedly tap it to make it go faster — but not so fast that the debouncing mistakes 2 presses for just one press, otherwise it’s net slower. i find myself actively making latency v.s. throughput decisions: i can preheat the oven by pressing “on”, dialing in the temperature, and then pressing “start”. or, i can press “on”, “start”, and then dial in the temperature and press “start” an extra time. preheating begins whenever you first press “start”, so this shaves off 5 seconds of preheat latency at the cost of 1 extra second spent on an extra button press.
i get irrationally angry every time i use a digital oven. the digital oven is like some looking glass into a half-dozen interlinking societal systems that have managed to settle into some totally unsatisfying equilibria… and they’ve stayed there for decades. it’s legitimately depressing.
man, in the kitchen, keep the controls simple.
Sometimes you need to react really quickly and turn down heat, if it takes you 5 sec more, the food might be burnt already. Lifting the pan might be a good „hack“ though.
: Ok, burning house down.
This may be old-fashioned, but have you considered using the stove to cook food and then selling the food? If we need to get technology involved, you could accept payments via square. Hell, you could probably even accept payment via blockchain.
But then again, how will the poor stove manufacturer continue to capture monetary value from your purchase? I just bought some delicious tamales from a coworkers mom, and I doubt she shared any of those ill-gotten gains with Samsung. Clearly this is a sector in need of disruption StoveCoin is sounding better and better. Plus, all the waste heat from mining can make kitchens as hot as operating a gas stove, which is what induction stoves are missing. Let me know when the ICO is happening!
I could buy a bunch of expensive hifi qualitu knobs and potentiometers and build my own panel to control the stove.
And then your toddler throws your phone in the toilet while you're making Christmas dinner, and you can't turn the thing off.
IMHO touch controls are popular because they are cheap to make and offer a simple way to integrate the hob onto a counter. For a lot of people that is important. For us (my partner is blind) it is not.
Edit: I read further and realized you got single plates too. The search continues....
https://universal.bertazzoni.com/products/professional-serie...
SMEG also has induction stoves with knobs but we don’t trust that brand.
And I also agree that the touch controls are absolutely the worst, they are abysmal. I see why they are done this way - it allows the entire plate to be wiped clean very easily. But I still wish you could have separate controls somewhere on the side, with actual tactile knobs.
WTF designed these things? Certainly not a chef!
A bialetti (moka) pot will not work because they're made from aluminum (no induction).
The whole thing upsets me so much that it's very high on my list for deciding if I can live in that country. If there is no gas cooking (most of North of Europe) un/-surprisingly the food is also terrible. Maybe there is sample-bias in my statement but I know literally nobody in my family or friends who owns a ceran/indusction stove and who is actually a great cook.
The only things better for cooking than gas are wood or coal fires. But gas is the next best natural flame.
No fuzz with running extra big wires for stove.
https://caffeinetalk.com/using-a-moka-pot-on-an-induction-st...
I honestly don't know thw reasoning for using toch controls on induction stoves. They are a pain to use for most people.
After a short while I could easily operate it while not looking, and precision control (half-steps) was easy by simply rolling finger.
Sadly very, very few seems to have this design. Some have a shared control, but having to select the zone and then power is just... not good in comparison. I have that on my current one and I routinely adjust the wrong one, split between forgetting to select zone and it not recognizing my zone selection.
It was still touch though which overall sucks compared to physical controls.
First complaint - exactly the same as yours. Even a little boil over can sometimes just shut everything off.
Second complaint - "smart" pan sensing. I have a few pots that don't really fit the rings on the stove perfectly, and they have been relegated to the "useless" corner of the cabinet. The temp setting starts to either flash whenever the pot isn't big enough to cover the ring, or just takes forever to heat up.
Last complaint - some of my pans are not perfectly flat on the bottom, from either a rough life or warping in the oven, etc. Those pans are also useless on the induction hob.
- You can't use a wok on them.
- In fact, you can't use them with lots of other things, or in many ways I use my gas stove. Yes, these are "off-label" uses, sometimes not even related to cooking. So? Tools should be flexible, not fight back.
Buy a cast-iron wok from Staub, they work wonderfully.
It weighs about 30% more than our old carbon steel wok, which doesn’t matter much in practice.
How long have you cooked with a gas stove? I would wager that if you spent decades cooking on induction you would have similar complaints about gas. I love cooking with gas, but also I love cooking with electric, and I imagine I could love cooking with induction. (3 minutes to boil sounds brilliant, who needs a dedicated electric teakettle.) The stuff I could do with precise control down to 100 degrees F, I don't even know but that sounds like it requires patience but allows wonders that are impossible with gas.
Not to say gas can't work wonders that are impossible with induction, but they're different tools and it's not fair to judge simply on the basis of a few missing features.
Also there are pans that don't work as well with gas in my experience. I suspect that if anyone lived with an induction stove for decades and tried to replace it with a gas stove they would also be complaining that half their pans don't work anymore, or at least don't work for the task they've been used for anymore.
I 100% run my vent while cooking. Curious how much of the bad gas I vent…
But it sounds like induction legitimately makes double boilers obsolete (and rather quaint and limited to be restricted to 212F when you have the free, precise choice of even heat at any temperature between 100F and 500F.)
The only thing induction can't do well are cooking hacks that utilize the open flame, like toasting tortillas or roasting peppers on the burner without a pan.
I have induction with knobs. It's no different. I suspect it's just a knob on the user side, and there's still the big steps behind-the-scenes.
My stove's induction knobs give me tactile feedback, but lack the granular control that a real analog knob has.
It's really weird. Granular and immediate control should be such an easy thing to do with electric.
It almost seems as if manufacturers are adding in these "steps" to make it more user friendly in the sense that you can say "I've turned it up to 3".
Is there any technical reason to have discrete steps?
The are big plus is it doubles as extra worktop as it’s just so big (and flat).
We bought a professional induction stove from a restaurant online on ebay for very cheap. One of the reasons is that all controls were "manual" and with "knobs". The amount of electronics on these is minimal.
Something like that is what I bought.
Of course it's silly that knobs would belong only to "premium" models.
Having bought an induction stove when refitting our kitchen, then replacing it with a different one a couple of months later, I can advise that the size of the elements matters. The 'linked zones' thing seems to be rubbish, and doesn't heat evenly (maybe it does on really high end stuff). I now have a three-element stove (60cm) - one really big one and two smaller ones. I don't think I've ever used 4 burners at once anyway...
I just wish there was an API for induction stoves; interfacing with a thermometer to keep a certain temperature, or for a set time, or even a removably physical control panel (i.e. knobs) that would let you put it away and keep the flat-top thing (which is actually really nice when you need the bench space).
Edit: https://www.hafactory.it/2015/10/19/miele-news-about-tempera...
You can set the knob, and turn it on and off with a relee, connected to a raspberry pi. We have temperature sensors on the "food side" of the pans and pots, since what we care about is the temperature that the food feels.
99% of the time we don't use it with the pis, but have a couple of recipes as Jupyter notebooks that we use the temp control and temp staging with.
One advantage of induction over gas here, is that the thermal mass of some induction pots and pans is almost zero, and temperature changes are instantaneous, so from the point of view of control algorithms, programming induction cooking is infinitely better than any other system that i've used, cause you don't have to solve a PDE to regulate the temperature. YOu can just turn it on if its too cold and off if its too hot, and that's it. +-0.5C of accuracy, which at the 100$ level for a single plate is unbeatable.
We spent ~400$ for 3 heats. 100% recommend.
One of the main issue with common domestic gas stoves is that the heat is not well distributed, and good pans don’t necessarily have a great thermal conductivity. This is a problem when what you’re hearing is not liquid enough to redistribute heat by convection. Another is that you don’t control the temperature of the flame, just its size. So temperature control is always finicky, particularly at low temperatures.
So personally I go for induction most of the time, and a barbecue when I need a flame.
I agree with you there. I've had gas for the last ten years, and recently moved to a place with induction. It's a significant change.
I had regular electric for a long time before I had gas, so there was an adjustment period there, too, but I got used to it pretty quickly. But induction is somehow very different from either of those two.
I've been on induction for six months, and I still have such a very hard time with temperature control that I cook at home a lot less than I used to. It has a thousand controls, but only seems to have two settings: surface of the sun, and off.
That said, I'm OK with the move toward eliminating natural gas in homes. I just wish I ended up with a regular electric stove top instead of induction. But it's an apartment, so you get what you get.
Gas is nice mainly for things that are really temperature sensitive like searing meat, using a wok, etc. Of course when cooking stuff like that you want good ventilation for this because otherwise you end up with a lot of grease and soot all over the kitchen. So, the pollution of gas matters less if you have that set up correctly.
The main reason gas is so nice for cooking is how quickly you can adjust the temperature. Induction plates also respond really quickly of course. The old fashioned red hot spiral things, are much more tricky because they stay hot for so long; it takes a minute to reduce the heat; or to raise it. I have one at home and I'm used to it but it is still annoying. A neat trick is to simply move pans away from the heat to control it.
Induction plates don't have that problem. But I really hate the touch controls many of these things have. They are very fiddly; especially with wet hands and they also can get hot. I'd prefer to have some old fashioned dials. But in terms of instant, fine grained control, they are actually pretty good.
We bought a profesional induction plate, 4.5kW, 100$ on ebay. Performance wise, its ~4x better than the 4kW gas stove it replaced. The time required to heat 50L of water to 60C went down from 60min with gas to about 10-15 min with induction.
Instantaneously hot, and instantaneously cold. For us it opened a lot of new ways of cooking.
What kind of cooking do you prefer doing on a gas stove over an induction stove?
Obviously the same pots and pans don't work on both, but if you have a top of the line induction stove you know this already.
I have a gas range with a high quality induction plate built into it. So I can boil water faster. But I hardly cook on it, for that gas is king.
I haven't cooked much on induction stoves. I only do so at my parents' place. So among the few things I cooked on both induction and stove, I know I prefer gas for cooking steaks and making scrambled eggs.
I know part of my frustration is with the touch controls, though, and I presume some of it is due to my lack of intuition with what setting is good for what sort of "cooking I want to apply to food".
I do agree with one of the replies to your comment, though: it seems like everyone just talks about how good induction is at boiling water and not much else specifically. I have an electric kettle for that job so it's not some alluring aspect to me.
Induction took some getting used to, but outside of a few very specific things (mainly stir-fry), it's better than gas across the board for me.
I think we as a society are over-prioritizing personal safety. I cringe whenever a business sends me a notification saying, "Your safety is our #1 priority!" and proceeds to explain why I won't be allowed to do yet another thing I am accustomed to do. My safety isn't my #1 priority, and I certainly don't want the companies I do business with to decide how safe I have to be. I'd rather live the way I want to live, and I'm not really bothered if my happiness cuts ten years off my life; I'd prefer seventy years of living to eighty years of not dying.
Sure electric instead of gas, bike instead of car, N95 instead of cloth, are all beneficial choices on an individual level, but it’s much more important for authorities to create incentives to encourage optimal behaviors.
Want to use a wood stove and understand the risks? Great! But maybe building codes are stricter to discourage using them in new construction and/or regulations require proper ventilation.
We shouldn’t expect every individual consumer to be an expert on indoor pollution, carbon emissions, and viral transmission. You’ll never get the kind of aggregate behavior needed for significant change, and the people most likely to suffer are those who don’t have the leisure time and ability to install NO2 sensors all over their house and contact friends who are experts.
I could not disagree more. First, I value personal freedom, and an important part of exercising freedom responsibly is being informed. Good information helps you make a choice that wisely balances what you want with what's wise. I read things like this with the question, "What should I do about this?" hanging in my mind, because that's the relevant question: do I alter my life based on this information, and if so, how?
"Authorities creating incentives to encourage optimal behaviors" is nice talk that is either a) a euphemism for making it illegal to do as you please, or b) a euphemism for making it prohibitively expensive to do as you please. In either case, it comes down to forcing people to act against their preferences but in accordance with the will of the authorities, which I can't agree to.
As far as the euphemisms hiding intent to control choice, I agree that can happen. But I think there is a area of nudging incentives before strict regulation. The classic example is changing organ donation from an opt-in to an opt-out system. Nobody’s choice was removed, but a small nudge can have a measurable systemic impact
If we can save and significantly improve lots of lives by improving appliances, that seems like a good outcome. I personally don't want resperitory problems - for myself, my family, or my neighbors - it makes it hard to enjoy all those other risky things I love.
> I cringe whenever a business sends me a notification saying, "Your safety is our #1 priority!" and proceeds to explain why I won't be allowed to do yet another thing I am accustomed to do.
I don't recall ever receiving a notice from a business telling me that I am not allowed to do something (other than for IP). Who is sending these notices? Can you provide an example?
This is a mis-framing of the relevant tradeoffs. Your options aren't a truncated life of joy vs. a longer life of asceticism. The tradeoff might instead be that one of your kids gets asthma and suffers with the condition for their entire life. Or maybe you get cancer and, yes, you die earlier, but it's not an instant death. Maybe you live with that cancer for a decade of treatment and remission and treatment again and ultimately an intense suffering like you've never experienced.
So instead of dying in your sleep at 80, you die of lung cancer at 70, which you were diagnosed with at 60, after a decade of struggling with the emphysema you discovered when you were 50.
You're not just rolling the dice on a shorter life weighed against a happier one; you're rolling for an increased likelihood of a much worse life (that's also shorter).
You're right that safety isn't always #1. But I hope you're thinking about the actual tradeoffs involved and not some kind of idealized version of them.
This is called safetyism. It’s the notion that perfectly safe conditions are worth the immense tradeoff they require, like removing individual freedom and agency. But it is also the recent trend of claiming safety matters above all other factors to an absolute degree, and that everyone should be forced to value it as such. We see this manifested in political actions that are absolute (mandates, bans etc). There are other definitions for safetyism as well (https://quillette.com/2018/09/02/is-safetyism-destroying-a-g... ). But my point is that life isn’t one size fits all and our policies shouldn’t be either.
Thanks for sharing your experience of working with wood alongside your family. These experiences and their value are unknown to most city dwellers, and they default to assigning zero value on these things when they propose banning everything that isn’t part of their own life. I get what you’re saying about a wood stove. There is value in that ritual and tradition and life’s pleasures. I personally love a gas range for a similar reason, which is that cooking over a flame is culturally important to me. I also find it is simply far better than my induction top for most cooking (except boiling water, for which I have a $20 electric kettle anyways).
In the case of gas stoves and gas furnaces, it’s astonishing that people ignore that most new setups vent to the outside, which is required in many areas. Even if NO2 is elevated, my feeling is that not everything in life has to be 100% clean or safe, since life inherently comes with risks and it is up to each individual to make personal choices about what risks to tolerate for the benefits. Most people cooking daily with gas stoves live long healthy lives and don’t have issues stemming from NO2 exposure and very few are sensitive enough that a minor elevation of NO2 would cause health issues. This is only a problem for the most sensitive of people.
So are gas ranges really a problem or just an overblown fear by proponents of safetyism or climate activists used to justify top down gas bans?
You're going to be disappointed then. Closer to 40 years of living, 30 years of being imprisoned by your failing health.
I support your right to make stupid decisions but at least make sure they're accurate and informed stupid decisions.
I'd take anything over the awful "student house electric oven" I have now though.
Induction hobs are much better in thst regard, but they fail in other ways - eg with gas i can lift the pan slightly above to shake it ans mix the food, with induction the second i get a few mm above the surface, the pan stops being heated.
Its a massive change in process and feel... Its a bit like going fron riding a motorbike (extremely responsive) to piloting a canal boat where action and effect can be minutes apart.
Seems like this problem would have been solved long ago if enough people actually cared about it...
This, of course, makes it unviable to produce a better product (like an electric stove with better temperature feedback/control) without dramatically increasing prices to make up for the loss in market share.
I don’t think it’s a “problem” per say, but it’s different. The flame indicates temperature in a way most people understand. Have you used a wok? How about cast iron? There’s a lot of nuance to certain dishes and methods that don’t work as well on an electric stove. The flame itself rises and hits the pan in three dimensions and a more distributed way.
I’m not saying it’s not okay (I’ve used an electric stove for a few years). But it’s not “puzzling” why people would like a flame to cook.
I think there are some nice electric stoves that use infrared heating and are plenty powerful and reasonably reactive, maybe that's what you have. Induction, of course, is even better.
Maybe the problem is really about price and quality. A gas stove will always work, even the cheapest gas stove has good temperature control and power. Even a camping stove can do decent cooking. You can also put anything on top of it, including your cheap bent aluminium frying pans. Cheap electric stoves lack power, and electric stoves, induction in particular require good quality, compatible cookware to work correctly.
Another problem with cheap electric stoves (especially induction) is that a lot of them have absolutely terrible capacitive switches that work half of the time. I never had this issue with knobs on a gas stove, even the cheap ones.
I didn't think people were using electric stoves to be a superset of induction stoves. As far as I can tell, there is no such thing as a cheap inductive stove, and the break down (where I live) is: low end - electric stoves, mid end - gas stoves, high end - induction stoves. Induction just has a lot of advantages in speed and cleanup.
The temperature is all over the map.
I had to simmer something at 180F and it took me 30 minutes to find the right power setting and a big pot of water to stabilize the temperature.
Do the American home building standards not take account of this?
Fairly certain it's already law for a while in other places, e.g. if you have a gas stove or central heating then you need greater ventilation and maybe carbon monoxide alarms and so forth.
New houses in some places aren't allowed to have gas connections at all, which is partly greenhouse gas related, but the health benefits and cost savings are part of the discussion. No new home today should be built around the assumption that gas is a sensible fuel source.
Gas furnace, stove, dryer and water heater are much nicer than the electric counterparts
For heating and hot water, "remote heat" is infinitely cheaper, both in acquisition and maintenance costs, and infinitely more environmentally friendly than gas and electric heating.
Sure, if you live in a remote region or a third world country, then you get what you can get. But in any modern first world city, there is no quality in the solution space in which gas is better than the alternatives, and as a whole, gas is just substantially worse.
Gas blows induction out of the water for actual cooking, not just reheating stuff
Actually, most of the world population (>50%, ~4 billion people) lives in dense urban areas since ~2007: https://ourworldindata.org/urbanization
The current trend is expected to continue to increase.
https://www.statista.com/statistics/985183/size-urban-rural-...
As one guy put it, there are more Republicans living in Orange County than there are in the entire state of Mississippi.
I've never seen a stove bring 8 qt of water to boil so quickly.
I've used both and induction clearly comes out on top, by a huge margin.
As for home heating with gas: wrong again - heat pumps are the superior method, and come with the benefits of being air conditioners as well.
“WHERE DO HEAT PUMPS WORK BEST? Heat pumps are more common in milder climates, where the temperature does not typically drop below freezing. In colder regions, *they can also be combined with furnaces*for energy-efficient heating on all but the coldest days. When the temperature outside drops too low for the heat pump to operate effectively, the system will instead use the furnace to generate heat. This kind of system is often called a dual fuel system – it is very energy efficient and cost effective.”
https://www.carrier.com/residential/en/us/products/heat-pump...
There's also the alternative of putting the outlet of the heat pump below ground, where the temperature never gets that far below zero.
It's entirely incorrect to say that heat pumps only work in mild climates. I live in a country where we do not have a mild climate, and heat pumps are becoming more popular each day, owing to their technological superiority.
I'm also not a fan of using buttons and touch controls on something like this when cooking. It's distracting and cumbersome. Lowering temperature requires multiple button presses when gas just lets me turn a knob to instantly put it on low

Like for example, if you're going to go to the expense of laying gas pipes for those furnaces, why not lay a geothermal loop instead and use that to boost the heat pumps output?
And, like the "EVs don't work in the cold" claim, there's lots of experience outside the US of EVs and heat pumps working well in cold climates. You might need to insulate your house or stop actively subsidizing fossil fuels to make it happen in the early stages but it's totally doable.
Once I airseal some more and fix some of the leaky storms I expect it to never resort to resistive at all.
Heat pumps do work in cold climates.
If you have remote heat, you don’t need a heat pump.
Heat pumps are expensive, and hard to service and maintain (though they usually have a long lifetime). Some of them use pretty toxic chemicals that you don’t really want leaking.
> Spouting this sort of head-in-the-clouds, wrong information only weakens your cause.
The only thing you are showing is your ignorance everywhere.
That's impressive. The top-of-the-line Bosch induction cooktop, which retails for $2500 USD, tops out at 3.3kW on the largest plate. The rest are all most like 1.7-2.2 each.
A four burner range that could pull off 4.5kW per plate would probably require a 100A 240V circuit. Woof.
I have a similar model to that one, but can’t find mine (it’s a bit older). That one cost 140€ and has 3.5kW. Mine was cheaper (~100€) and has 4.5kW, which is insane.
I'm also not saying the gas stove has no effect, just that they don't seem to be controlling for ambient NO2.
Ideally capable of sending data to be stored & processed locally (Home Assistant or similar).
I have a dozen or so ESP32 boards littering my desk left over from a work project, so that sounds perfect :)
I wish residential vent hoods came with interconnects like commercial kitchens so they would come on automatically whenever cooking.
Adding the make-up air system increases the cost by 50% or something (needs a similarly powerful fan and similarly sized duct for air coming in vs. going out), but any powerful vent hood should probably include one (and building codes demand them in many places, though I think this is often overlooked in practice).
After doing the routine checks, the AC was fine. Upon further investigation, there was no make up air. The owner decided to delete the MUA out of the design to save money (didn’t listen to his MEP designer). Not only was the kitchen vent hood exhausting kitchen air but conditioned restaurant air as well. It was permitted city construction, I have no clue how the place passed inspection.
From the linked study (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4909253/):
> Ventilation hood installation did not significantly reduce indoor NO2 concentrations in our study, and there was a trend toward higher NO2 concentrations in follow-up visits, although not statistically significant. The reason for the lack of efficacy of ventilation hoods is uncertain.
The research explains that the lack of effectiveness of hoods could be due to many factors (improper installation, lack of use), but at least at first glance it seems that a hood doesn't help with NO2.
As someone who has always preferred a gas stove over electric, this doesn't really align with what I want to believe =). But I also realize there are many times I preheat the oven and cook a frozen lasagna for 50 mins or boil water on the stove without turning on my range hood, so I definitely understand at least one reason that a gas stove with a range hood may not help in terms of reducing NO2 levels in my house. I tend to use the range hood if I'm cooking something really smelly or messy (ie frying), but don't think of it if I'm just baking something in the gas oven for a long period of time.
I know for my part I'm going to be buying an induction cook top for things like boiling water or frying foods where I really don't need gas. I have kids and don't really wanna add to risk of air pollutant exposure.

I don’t know if you can claim a hood doesn’t help. As you noted, the study admits they don’t know if hoods were even turned on by the residents. It simply doesn’t make sense that hoods venting to the outside would have no effect, and so I have to imagine this is a lack of appropriate controls over the experiment here.
Don't know about NO2 or VOC.
I did this because I live in a converted industrial loft, so my furnace and hot water heater are essentially in the same space as my bed, and having open flames in the same space seemed risky.
Modern furnaces release a lot less heat as waste, one result of that is that there aren't a lot of hot gases to deal with, a flue isn't necessary.
Same with furnaces, heaters, etc.
I like my current setup - the entire boiler is outside and away from any windows.
Consider that induction stoves emit EMFs roughly 16 times the “safe” limit for non-ionizing radiation [1]. And when you’re cooking, the parts of the body that are most likely to be exposed to the highest EMFs are your reproductive systems and the heads of children, which the study cited above notes can be damaged by EMFs 8x weaker than those from an induction stove.
Investigate and consider all the health risks of your decisions. It may be very well possible that one form of pollution (air) is no worse than another type (electromagnetic).

From the paper linked[1]:
"the exposure of the non-pregnant models at the largest distance (300 mm from the cabinet) is always compliant with the basic restrictions for the general public even when including all body tissues for the current averaging."
And to consider the case of close distances...
"the exposure limits for the general public can be exceeded by more than a factor of 5 (distance < 50 mm; Fig. 5). When considering CNS tissues only, the basic restrictions for the general public can be reached for the child models (Thelonious and Roberta) at close distances from the cabinet edge when allowing for the overall uncertainty of this evaluation. The combined numerical and experimental uncertainty was assessed as 6.0 dB (k = 2; Supplementary Table V) or as 0.50–2.0 of the provided exposure with a confidence interval of 95%."
I read this as don't push your kids face onto the stove top, which is probably good advice no matter what cook surface you're using. It also reads to me as having the cooktop being further back as desirable, and not being directly inline with the edge of the counter.
As for pregnant mothers...
"The exposure of the mother and fetus models exceeds the basic restrictions for the general public by a factor of 6 for the mother and 3.5 for the fetus when standing at the cabinet edge, if considering all body tissues. Given the numerical and experimental uncertainty, the violation of the occupational limits can be regarded as likely for the devices with high B-fields. For CNS tissues of the fetus, the induced current density can reach the order of magnitude of the basic restrictions when taking into account the uncertainty. The combined numerical and experimental uncertainty for the exposure of the fetus was assessed as 6.4 dB (k = 2; Supplementary Table VI) or as 0.48–2.1 of the provided exposure with a confidence interval of 95%."
From this data, it seems to me that the best way to use these devices is to force yourself to 'reach' over the countertop rather than being directly up against the cook surface.
From the summary of the paper.
"The measured B-fields of 13 professional induction cooktops and the three domestic devices evaluated in Viellard et al. [2006] were evaluated experimentally. The field strengths are compliant with exposure limits for the general public when measured at 300 mm from the cooktops as specified by IEC 62233 [IEC, 2005]. The current densities reached the exposure limits according to the ICNIRP 1998 guidelines for the general public at 300 mm from the cooktop. The results were then scaled to the measured B-field levels of the professional and domestic cooktops. The findings can be summarized as follows: Most of the measured cooktops are compliant with the field limits for public exposure at a distance of 300 mm from the cooktop. Due to the high field gradients in the close environment of the cooking zone, most devices exceed these limits at closer distances. When considering the entire body of the exposed user for the current density averaging, the basic restrictions of the current density for the general public can be significantly exceeded and reach occupational levels. A generic worst-case cooktop which is compliant at the measurement distance specified by IEC 62233 can lead to current densities that exceed the basic restrictions for the general public by a factor of 16. The brain tissue of young children can be overexposed by a factor of 2 with respect to the basic restrictions for the general public if they come close to the cooktop. If exposure limits of the general public apply to the fetus of a mother in a working environment, the current density in the CNS tissue of the fetus can exceed the basic restrictions while they are still fulfilled for the mother."
There's pros/cons with any cooking devices, and it makes sense to consider the potential risks with any heat source. With that said, we are not talking about the induction burner spewing these fields across your entire kitchen, unlike say, with gas burners. From my point of view given your source's data, it is still a much healthier option to operate these devices properly than to subject the family preparing the meal in the kitchen with me to a poisonous gas.
Anecdotally speaking, my rental doesn't have a fume hood (yes in 2022!), and if the gas burners are operated my partner gets nauseous with headaches sitting in the other room. The benefits of induction are quite clear and until something better comes along, I don't see myself ever going backwards to inferior heating devices.
The range hood on average American houses are weak, because they are the cheapest. Till I got a range hood built by an Asian manufacturer(Fotile) did I know what I was missing out. Range hoods are measured by the amount of air it can move, CFM.
Futile starts out at 850...while regular ones (GE, for example) are 300, 400. And it's not even a price thing...there are range hoods near the price of Fotile which still only do 400 CFM!
I turn on the fan before turning on the gas stove, and leave it on for a bit after cooking.
The reasons I call out Chinese range hoods is because stir frying is a huge part of cooking and you gotta have something powerful enough to pull out everything.
Entirely possible I have a source by default...I do have a chimney and even with the flute closed I feel a draft. All I know is in the past, before replacing my hood I can smell the cooking from upstairs...now I can't.
Ok, but having just shopped for range hoods (and purchased a 1000 CFM Thermador hood) there are plenty of good hoods in the same price range by various manufacturers that do 800-1000 CFM. I'm not trying to say the Fotile hoods aren't good, I honestly didn't look at those. But I don't think there's anything particularly unique about the fact that they do 800+ CFM.
You're right though, there are plenty of underpowered hoods out there also, and one should definitely pay attention when purchasing, along with other factors such as source of make up air.
If the real goal is to ban gas stoves because of climate change it needs to be said upfront. From this perspective the problem isn’t the 0.12% direct emissions but that people like it enough to generate demand for residential gas service at all.
My preferred setup would be 4 induction burners with one or two gas burners. I understand if you have a house without gas, it does't feel worthwhile to just have one or two burners. Induction would be the daily drivers, i.e. boiling water. The gas would for occasions where I want tighter heat control or want to use a pot/pan that doesn't work with induction.
I've never seen a stove without a vent hood above it...?
But many are just mesh grease filters and are never changed.
I’m installing a wood burning and an electric stove in my current house.
If you are interested in technicalities:
- 5-15% loss in power transporting energy [1]
- 30-40% efficiency of natural gas turbines (where most power comes from, 2nd highest is coal; which is worse)[2]
- 80% efficiency induction heating [3]
- in all likelihood (haven’t done math). The heat lost from wood stove cooking heats your house and cooks your food with a renewable resource. It’s likely more efficient than induction.

for taste charcoal/wood > gas > electric IMO.
Give me gas, every time. Especially when stir frying or flambe-ing or working on the hibachi grill or teppan grill or grilling.
An electric oven is "okay" except for the heat/cool cycle which frankly is just annoying when baking bread.
I got to use an electric salamander once, and that was a huge disappointment. Nothing matches gas for flexibility and control and unassisted convection heat transfer. When I turn the pan on the side to get more heat there for braising, I get more there, right _there_, not over there, not over here, not all around, right there.
The other thing with a gas range, when I'm pulling a 500F pan out of the oven and dropping it on the range, or dragging 30lb of hot liquid in a stock pot across the top, I'm not worried about damaging anything except my back. I don't need $5,000+ of hardware in my kitchen being taken out of commission because someone was slightly careless.

I'm not disputing anything, I'm sure they do all that. I'd love to read some detail about it or a third party review that did a comparison with a reference device. It would also be cool to place some of their detectors side by side and see how much they agree on the measurements.
I was glad to have it as a backup plan.
As in, boiling the water? Wasn’t it very humid?
I would welcome a couple of boiling pots in my room right now.

I agree, it was a really bad idea, but better than letting the pipes freeze.
Why is my gas stove a problem?

So of course this guy sees more things on the days he cooks and not on the day he gets takeout. On the take out day run a burger and measure. You won’t see much. Not compared to cooking in general. Get some induction plates and cook and note the results.
“Studies” show kids that grow up in cities acquire asthma at higher rates and also that dwellings in cities are more likely to have gas appliances.
That said I wouldn't stand with my balls next to the front burner on an induction stove due the EMF. I stand a few inches back.
The recommendation is to primarily use the back burners and occasional front burner use as required.
I've tested this with an EMF meter and it's pretty bad right up against my stove.
The OP neglects this entirely. Maybe you save on the respiratory illness by converting to electric or induction from gas, but you now expose yourself to EMFs instead of dirty air. I don’t have solid info on which is the worse environmental contaminant but am reasonably certain there is no “safe” way to cook.
For a more comprehensive treatment on the health and ecological consequences I'd recommend The Invisible Rainbow by Arthur Firstenberg. It discusses the topic in depth with respect to humans, insects, birds, trees, and more, across hundreds of years of history. It's very well researched; its references are 2/3 as long as the entire book.
The Body Electric by Dr. Robert Becker is another book to possibly look into. It talks about electricity from a medical perspective and talks a bit about the mechanisms by which electricity influence the body and what it can do. If nothing else, the interesting takeaway for me from this book was that he was able to induce limb regrowth in tissue using currents on the order of picoamperes (this is an unfathomably small current compared to what we interface with daily). He also notes that more or less is not necessarily worse in terms of electricity's impacts on the body, just different.
Here are some interesting highlights I've chosen from The Invisible Rainbow to give a broad sample.
Impact of Mobile Phones on the Density of Honeybees: https://www.stopsmartmetersbc.com/wp-content/uploads/2017/04...
Biological Effects and Health Implications of Microwave Radiation: https://books.googleusercontent.com/books/content?req=AKW5Qa...
There are compelling references throughout the book implicating EMFs in diabetes, heart disease, possibly cancer, and illness, to name a couple.
Great title and good book but the implications are depressing. Hopefully our situation is not THAT bad.
An easier solution to the actual problem is to open a couple of windows slightly.
The obsession with sealed living spaces to yield marginal savings in HVAC has pretty obvious downsides and measurable, marginal savings.
For example, natural gas powers my furnace, water heater, stove, and fireplace, as is common in the midwestern US. It would be impractical, not to mention expensive and wasteful to upgrade my electrical system to 200A and replace each appliance. Utility costs would increase too, and I couldn't use my fireplace or range when the power goes out (a battery backup would solve this, for another $2k).
I heat my entire home with electric, baseboard heaters, and have 200A. And it gets to -40C where I live!
(Power comes from hydroelectric, and is cheap)
What are you doing?
My hope is that the net effect of this will be to essentially eliminate air exchange between the boiler and the rest of the house. (Note that our heat system's air exchangers are not in the same room as the boiler.) I kinda want to see what the indoor air quality is looking like before and after.
Personally, I don't intend to exchange out my gas stove for a while since as this article points out the vast majority of gas burned in the house is for heating, not cooking.
I had a gas stove in the US but honestly I don’t see a big difference between gas and induction.

With a high efficiency furnace the combustion air comes from outside and is directly vented outside.
That leaves water heaters which are vented either up the chimney (mostly these days with a liner) or a forced air vent.
A mid or low efficiency furnace vented to a chimney without a liner could well result in combustion products leaking through the chimney into the house.
Heat exchanger leaks could also be a factor, but usually the duct space is higher pressure than the vent which has the chimney draft. Leakage can still happen before the draft develops after ignition.
With gas the challenge is to ensure the flame hasn't gone out.
With induction the challenge appears to be partial cycling (microwave-style) or simply just reducing power down to bare minimum.
For some things, say an authentic bolognese sauce or a chakchouka, I desperately want a tiny amount of heat, but neither modern gas cookers, or most induction cookers, will give me that. Xiaomi (yes, that Xiaomi) have a 0-99 induction cooker that nearly got me there, but even then I had to utilise a diffusion plate.
In our last remodel we put in a damn expensive Wolf range and a tankless water heater, both propane fueled. Both work great. That being said, all the press on NO2 have made us always turn on the vent when cooking, something we did not do before.
My previous dealing with induction was crap. Yes I understand the pan makeup part. That was years ago. The technology has progressed since then and next kit will be induction and electrical powered water heater, driven by a solar backed power wall type system.
This is the big problem with climate change and how it’s presented. It’s far too ambiguous for any one person to be able to make an actionable difference. So companies that sell products (like induction ranges) execute a campaign that enables individuals to feel like they are making a difference while selling them a product
The irony is that the carbon cost to manufacture and distribute that new induction range will likely offset any amount of future carbon burned from simply continuing to use and repair your current range. If you’re in the market for a new range then yes consider induction.
But if your stove is working fine, the better action is to write to your elected officials and encourage them to make policies that have a far broader impact than how you make your eggs each morning.
https://www.epa.gov/greenvehicles/fast-facts-transportation-...
Transportation accounts for nearly 1/3 of the US's greenhouse gas emissions and has been the fastest growing contributor. The vast majority of that comes from light and medium duty vehicles so personal cars and trucks.
If we stopping building our cities to require driving and electrify where we can, we'll see a huge reduction in GHG emissions.
Accordingly Metro Vancouver wants to get people to stop heating their homes and water with gas.
If people think they "need" gas stoves that can be a barrier to moving them toward electric heating. If they "need" gas for the stove, might as well heat with it too.
Creating greater understanding of the health risks of gas ranges and that induction stoves are just as good if not better is good in helping make people more comfortable with the idea of shifting to electric next time they need to replace a main component of their heating system.
> I looked at the energy usage data from our Nest thermostat and discovered that those levels corresponded almost exactly with the times that our gas furnace was on.
Another way of seeing this could be that nest is turning on the heat between 2am and 7am, and it looks like the author was not aware of this. so yeah the gas stove is bad but not as much as the heating system, and the fact that a "smart thermostat" turns it on at night when it should be less useful.
Another way to look at the this is checking the health outcomes of chefs, given they spend much more time next to the stove we should see increased respiratory problems.
I mean who doesn't spill when cooking?
Cooking with induction is like cooking in a video game in comparison. No thanks.
Is this a thing, wanting to convince people to get rid of furnaces and hot water heaters? Are we replacing them with anything? Seems like an extremely tough sell, especially for people living places that are cold. Take the poor little boy who just died because his “family” forced him to take an ice cold shower in the middle of winter as punishment. This seems like the hairbrained idea of people who don’t experience seasons.
