Please can someone offer some advice as my heating system has gone mad! Its a Glowworm boiler and when the heating comes on or I turn up the thermostat, it fires up and goes for a few minutes then closes down, few minutes later it fires up and then closes down and will do this until I turn the thermostat down.
The radiators get hot but I have noticed an unusual sound in the one nearest the boiler, its like a "trying to draw air in" noise, sorry I can't describe it better than that.
I looked through previous posts and tried bleeding the radiators and undid the screw on the pump, no water came out but it made a whirring noise.
The silver box which switches between hot water and central heating says sundial y plan 3 position diverter.
Hope thats enough information.
Thank you.
