It would not work for me as I usually have the house around 16 degrees C in winter. Needless to say my energy bill is very low :)
Interesting because I could regulate mine after all the radiators were replaced around 20 years ago.
And I kind of had to because the workers installing them made a mistake and I got the radiator meant for the living room, so it was grossly oversized for the space it heated.
That being said it's usually mandatory to keep them at least half-open considering that the heat is shared with other apartments.
I now live in a building from the early 90s and the knobs are all functional but I don't use them because the city pumps heat according to the weather outside.
Yeah that was kinda the thing. She could technically close it but then the neighbours would complain.
I would hate that as most of the time I use no heating (or cooling) at all. Also, I wouldn't like to pay for it if I don't even use it.
PS: I live in a nicely mild-climated mediterranean coastal city so I can imagine "not using the heater" is not really a done thing if you live in Finland :)
I was only visiting, so I don't know if it was the original design, or if the valves have jammed.
Offices have multiple thermostats per floor.
Ofc, it the thermostats used are bad there might be problems.
