One radiator Cold

[jamesgreenway]

Hi - wonder if you can help

My heating system is working fine - all of the rads are red hot!! Only problem is that one of the radiators is stone cold - i've tried to bleed it but this doesn't seem to have any effect.

Has anyone any suggestions???

Cheers

If it Has a Thermostatic valve,remove the head and see if the pin is stuck down?
Quite a common fault as they get older or been stood over summer.Give the pin a gentle pull with your pliers to release it but be carefull you dont pull it out.Sometimes they need working in and out a bit but If it is that then Ideally it should be replaced.

If it is a stuck TRV I wouldn't recommend pulling out the pin as I've known them come out completely. Take a look at the FAQ here...//www.diynot.com/forums/viewtopic.php?p=243077#243077

Hi fella's - unfortunately its not a faulty valve, i did think that might have been the problem initially but i tried it and its not remedied anything.

The radiator was removed and replaced recently for decorating. I've tried to bleed it but cold water just keeps p*ssing out....

Have u tried opening the lockshield valve on the other side of the radiator (The opposite end of the TRV)?

This might still be closed- Open it anticlockwise;

The system may need rebalancing, but atleast that rad shall be up and running. For advice on how to rebalance, see FAQs;

Hope this helps
