Hi

I have just put on my central heating but it is not working,the hot water works fine but when i switch on the heating it fires up for about 20 secs then goes down to min flame and the radiators dont warm up.The pipe at the back of the boiler is warming up but it dosent seem to reach the rads.
I tried bleeding all rads but they seem fine.

The boiler is a worcester greenstar 24i junior.

Any help would be greatly appreciated
Thanks
Paul

Have you checked that the room stat is calling for heat?

Hi
