Hello! I was wondering if somebody could help me? I have a cold radiator in a downstairs room which I have tried bleeding and letting water out from the top valve, radiator gets hot gradually but as soon as I stop it goes cold. The pipe to the left hand side of radiator gets hot after bleeding but the pipe from the TRV right hand side is stone cold and never gets hot.
Do I have an air lock if so what do I do? I am a complete novice!
Thank you
