Garald Posted February 7, 2023 Share Posted February 7, 2023 I just found myself trying to decide between a 2m tall radiator (which already has more power than I need) and a 220mm tall radiator. (Both are 60cm wide.) And so the thought struck me: is there such a thing as a radiator that is too tall? Won't the extra power be lost, in that the top bit will be heating mainly the air that will start over my head and go only upwards from there? (OK, it will eventually go down, by convection, but...)

Mike Posted February 7, 2023 Share Posted February 7, 2023 (edited) 51 minutes ago, Garald said: 2m tall / 220mm tall. That's a huge height difference. Convected heat from a low radiator will also tend to convect up to the ceiling before descending, so it may make less difference than expected - but the turbulence air in the room would be a factor in that. Of course the radiated heat won't be directly affected by that. As long as it's adequately sized and has a thermostatic valve, I wouldn't be too concerned.
