Ravenheat (I know not the best boiler) Combi gas boiler sealed system.
Downstairs rads not working (2 rads) upstairs rads (3 rads) piping hot. I have tried bleeding/balancing/removing rads all the usual. The pipes into the downstairs rads are hot but the return pipes are cool. The rads only get about 20% hot.
Hot water working OK.
I have just noticed that when I turn off all my upstairs rads and try to force the flow down the boiler makes some rather large noises and sounds like its fill with water then bang then the boiler shuts off.
Is my pump gone? It's very hot to touch. I have blead the screw - no air.
It does should like it's going round but I can't be sure. I have been advised to try a pub replacement.
What do you think?
Thanks for advance.
