Is your central heating coming on, or are certain radiators warming up when the hot water is on?

Expert:  Andrew Smith replied 2 years ago.

ok, a couple of things that can fire the boiler;

the room stat

The hot tap

A frost stat

Any of these if fualty can fire the boiler, you should try and disable each one for a couple of hours and see if it still fires up.

Is there any pattern to it?
