Hi, my central heating pump has recently started making a noise. I keep removing the screw in the centre, to bleed it, sometimes I get air out, sometimes just a little water. I have also tried bleeding the radiators.
The thing is, I have noticed that the pump seems to be on continuously, even when the heating & hot water is off on the programmer. The room thermostat is also down low.
Is there a thermostat somewhere that should be turning the pump on & off. ie the one on the hot water tank or one in the boiler.
My boiler is a Glow Worm Fuelsaver F.
Thanks
