Heater not Heating up

[a1tone]

Hi

I have a central heating system in my house. We have 10 heater around the house, but 2 don't heat up.

These are both upstairs, but all the others upstairs work.

The pips leading to the heater are warm, but doesn't get into the heater. They are both turned on. I have tried bleeding them both and water comes out, so I assume they are ok.

Any suggestions will be welcome.

Cheers

How old are the rads, they are probably sludged up, if they are old as you say you have bleed them

do the cold rads have trvs, if so could be stuck

The radiators are about 10 years old. We've just moved into the house, used to be my Grandma's and the one's that arn't working she never used.

The radiators do have trv's

So as above says the t/stat valves may be stuck.
Give make & someone may help in telling how to unstick them

The trv's are Westherm.
