We have a combi boiler - and radiators in every room. One radiator only is not working. It becomes mildly warm but that is all. I thought the problem might be the thermostat on the rad, or, less likely perhaps, that there may be air in the system (the radiator is in the middle floor of three floors) - Is there a way of checking/ repairing the thermostat or of bleeding the system?

in the current cold snap the thermostatic radiator valves are probably open all over the house and by passing this one rad. Shut all the rest down and check if it then heats up.

Many thanks John - I appreciate your help...and you were right!

That means that your system needs balancing to ensure that all radiators get an equitable share of hot water when they are all on.
