Im no expert but i dont think it is a problem with the boiler. The boiler does not fire up when the timer is off. The boiler is a baxi solo pf50.
Should the pump contiue to run after to heating and cenral heat is turned off ?
I have an intermittant problem where the living room heats up way in eccess of the setting on the room thermostat.
Not sure if its connected but when i turn off everything off at the programmer and the pump next to the hotwater tank keeps running. This happens with both the hot water only on...
