Hot upstairs but cold downstairs Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

A very odd problem! I have just replaced a worn out radiator and separate heated towel rail in the bathroom with a trendy new combined rad/rail. It is connected to a normal pumped central heating system. Obviously I drained the system before installing, now having recommissioned the system I am getting very hot radiators in the bathroom and all the bedrooms but no heat from the downstairs rads. Any suggestions? Air lock somewhere maybe? If so how do I shift it?
Cheers Nick B

Turn off all the hot rads, usually that shifts any airlocks

Thanks Marrtin - you are a star! Tried it and it worked first time - I am impressed. It will be stored away in my mind for future reference!
