Hello all,
I live in a flat that has communal heating through a single pipe system. I recently had replaced a deco flat panel (waffle) radiator with a more mundane type 22 panel radiator. The problem is that the new radiator sort of worked in the beginning, but it does not emit any heat now. When it sort of worked, what puzzled me was that the return pipe was getting warm, while the flow pipe was not warm, when it actually should be the opposite. Now that that radiator is cold, I bled the radiator to see what happened, and the return pipe got warm (but radiator remained cold) and the flow pipe was cold. Now they are both cold. I did not have this problem with the previous radiator, and I think I may have found out why but I need the experts' opinion. The original radiator was taller, whereas this new one is much shorter and the way the plumber installed it point B is higher than point A, and given that this is a gravity based single-pipe system, the water cannot enter through flow Point A, because return Point B is higher than A. Is that the case? With the original radiator this misalignment did not exist because the radiator was taller and thus point B was lower than point A. If that is the case, should I lower the radiator (so that B is lower than A) or would a radiator pump solve the problem?
