One cold radiator

[mrjames]

Hi all,

I've done a quick search but been unable to find a similar problem. Firstly i have Combi boiler. One radiator in the house has recently begun to stay cool, upon checking it....no air etc..i noticed that one of the connecting pipes is only just warm.

The radiator has a thermostat on it an coincidently the cold pipe leads to this end, whether or not this is significant...only you guys know

Anyway any help is appreciated..

Whole heating system has been flushed properly using the machine and chemicals.

ok edit.. just checked it again, seems fairly hot at the top but cool at the bottom...one pipe is still cooler than the other.

The TRV could have got stuck.Try taking the head off and pressing the pin in or very gently tapping it (the pin) to free it off.As noted before on this forum do not pull the pin out.
