hi, my above boiler has just developed a mind of it's own the boiler keeps firing up & shutting down repeatedly on the central heating side even though the room thermostat isn't calling for the heating to come on.
to stop it happening i have to switch the central heating side of it off, the hot water works fine.
does anyone have any idea what it could possibly be?.
Many thanks.
