Cold Radiator problem

[Brian_McCabe]

Can anyone help me with this problem. In the nursery the radiator is stone cold. The pipe leading into the lockshield valve is hot but nothing goes into the radiator. The other end where there is a trv is cold. Does anyone know how to solve this problem. I have bled the radiator and that is fine but I can't get it going.

Any help would be much appreciated.

This sounds like the TRV is stuck closed... ie no flow through radiator? If you remove the head off the TRV valve there is a little pin that you can move slightly as these are prone to sticking.... (Dont move pin to far as could pop out?)

Also could try closing all other radiator valves to see if pressure will force water through rad!!

He's right. Get the pin in a pair of pliers or suchlike... if it comes all the way out, it isnt a disaster, just put it back in, refix the head of the trv and more than likely, bob is the brother of your sister.

If bob is the brother of your sister..... then bob's your uncle!

Revenge will be mine.

Ask me to do a hydraulic resistance calculation longhand and blindfold.... no problem....ask me to crack a joke and I'm lost.
