The hot water system works perfectly but when i turn the central heating on the boiler doesnt make a noise anymore (it use to always have that low rumbling noise when you turn the heating on). However the radiators will still get hot for 5mins before cooling down again.
So far Ive tried to bleed the system for air and it didnt do anything, the pump seems to still be working as it vibrates slightly and has a low humming noise and i think the thermostat is also still working
any help is appreciated, thanks
