Cold Radiators


Postby peewee33 » Sun Feb 22, 2009 10:02 pm

Hi Guys, Just wondering if anyone could give me any idea as to why the rads in my house have stopped working.

The boiler is downstairs, pump is upstairs but the rads downstairs wont heat up but the ones upstairs are doing.... I had to turn water off to the house and empty the system to fix a leak and now I have this problem. Hot water is working but rads downstairs are refusing to heat up, also the boiler is only turning on intermitantly and only for a few minutes at a time, not long enough to heat the rads.

Thanks for your help in advance

Hi,

Sounds like an airlock after re-filling, bleed the pump and switch up pump speed.If this fails drain down again.

thanx for your post but actually I've had to turn the pump off because it's running constantly.

I have now turned some of the rads off and its has warmed the others up. Boiler still turning on intermitently
