I've just moved into a house and am having problems with the central heating.
Basically the red water pump has been going constantly all night and is now very hot to touch. ?
I can't see how to turn it off or find out if there is a problem with it?
We haven't got the heating on and only hoy water at the moment so can't understand why it sounds like it's pumping all the time?
Boiler is an ideal icos?
