Ironically the core application is written in rails, which may be part of the issue
TIL American English treats “value” in the financial sense as a countable noun
For temperatures significantly into negative territory a ground source heat pump would perform far better, where it can draw on a source of heat that will always be at least above freezing.
A hybrid system doesn't seem like a bad trade-off though..
That’s the point, surely
It’s only been 85 years, give it a bit more time…
I see asserts as a less temporary version of print() based debugging. Sometimes very useful as a quick and dirty fix, but 9 times out of 10 you’re better off with some combination of a real debugger, unit tests, tracing/logging, and better typing or validation.
Might provide some benefits on really hot days, but it’s still uncomfortably warm for working in.
In reality, a very good gas based system that is well specified and installed might reach 80% as a whole. Most UK gas/oil heating systems are significantly lower.
1. A system that also provides cooling isn’t allowed under the heat pump government grant.
2. You might actually need planning permission for this
3. Especially in a humid environment like the uk, you can end up with condensation and damp issues, which you really don’t want in an underfloor slab install
If you also want cooling, better to go an air-air based system (aka air conditioning)
What matters is the SCOP for the system as a whole.
In a traditional Victorian house with a fireplace in every room, radiant heat will provide far greater efficiency than a forced air system, in which all of that warm air will literally go straight up the chimney.
Thus you get plumbers with experience installing gas boilers, resulting in poorly specified and installed systems that provide nowhere near the efficiency that they should reach.
This then leads people to say “heat pumps don’t work” or “heat pumps are expensive to run”, which only feeds into the whole anti net-zero rhetoric.
Definitely some similarities though, I’d love to see some concrete technical information on it.
It took them two years to fix it.
Better instead just to have shorter TTL certs.
