I have a radiator in a bedroom which today stays cold when the ch system is on, I have checked and there is no air in the rad, just cold water whilst all the other radiators in the house are hot. It is fitted with thermostatic rad valve and I have tried swapping the top from a working radiator but that made no difference, the system is from a combi boiler and pressure is good. Any help would be appreciated.

did you check the pin on the trv is free ?
Hi,
Yes checked the pin and it is free, have just tried opening bleed valve and letting it run for a while, eventually the water that came out was slightly warmer than it had been. The radiator now feels slightly warm at the top only, all other radiators are very hot.
