Hi guys,

I have a Combi boiler Fitted upstairs in my house and when I fire it up, for some reason the radeators don't get hot. after a few minutes the pipes from the boiler get hot but still the radiators don't. all the radiator valves are open and the pump seams to be rotating. Please could some one help me. thanks

Check the system pressure.

Does the combi provide DHW when you expect it?

How do you know that the pump is rotating?

Hi guys,

The system pressure is at 1.2 bar. The combi provide DHW when you expect it and i took the end cap of the pump when it was running and i could the feel the pump shaft moving. Hope this is a bit more help.

Thanks Arron

It would also help if you told us the make and model of combi.

Not all combi's use the pump when trigggered for DHW.
