Hi All,
I took a radiator off and put back on to do some decorating. After re-installing it my heating pump (Grundfos 15/60) had a loud screeching noise. I googled the symptoms and it advised that I should bleed the system. I have bled all rads and also the pump itself. The noise has gone away (although it still hums a little) but now when I turn my heating on, it comes on and works for 10 mins, but then it appears to stop calling for heat and the boiler switches off. The first rad gets warm, so hot water must get to it. But not hot (as the boiler goes off by then).
Is there anything other basic I should check before calling a plumber?
The system is a vented system with a cold water and hot water tank (no F&E tank).
I’ve checked the obvious things like the room stat, and that is set to 30 so is calling for heat.
