I have a problem with one upstairs radiator not warming up. I drained the system a few months ago, before doing this the radiator warmed up ok. I have tried bleeding it with no success and i have ensured the thermostatic control is also ok. The radiator is full of water but the pipes from either side of the radiator are cold. I suspect an air lock, can anyone give me any advice how to overcome this problem please?
try turning off all the radiators bar that one.
or if you have a thermostatic rad valve it could be stuck in the off postion.
if all else fails youve got a blockage in your pipes
