Cold radiators

[Mel13]

Please can someone advise me of the next step? I have two cold radiators that were working last year. Im not very good with DIY things (laymans terms please!) but I have bled the radiators and also removed the tvrs and loosened the pins and still nothing. Is there anything else I can do myself??

Many thanks in advance x

when you bleed them is there pressure?

have you topped up the system after bleeding?

As soon as I turn the key water comes out, the plumber that serviced my boiler also said that he bled them at the time. As water comes out immediately I'd guess it wouldnt need topping up?? (Also I wouldnt know how to do that.... )

did your plumber not have more to offer? ...

 

[Mel13]

No, apparently during the boiler check he only makes sure that the heat is going to the radiators- not that they are actually working (the pipes leading to the radiators are hot)

new valves then.

Argh, that sounds like a competent persons job

hi, may need to balance the system a bit, turn down valves else where on the lockshields/trvs. Try a turn of most of the rads leaving one or so open and then this may draw the heat to the ones not working. then balance out the system re instating other rads slowly.

Ok, I will try that before I call for help! Thankyou.

pins may need a good banging, but caution must be applied.. you could make them leak ^^

however having just read message again, if the pipes are hot upto the valves then it would possibly be an issue with the valves as stated already. If you have checked the pins on the trvs then it maybe time to change. However previous post could still be worth a go.
