    Heating stays on all time, thermostat does not switch it off

    Came back after a night out to find the house very hot indeed. Had a play with the thermostat (set to 18degC) and it clicked at 27degC. So whatever the system's doing it isn't reacting to inputs from the thermostat. I've turned the radiator water temp down at the boiler, which means the...

    It used to be a student place but the decor got upgraded so is now full of 30/40something divorcees!! :lol: Now the settings have been changed so the heating doesn't anti-cycle so much, it is now apparent that some of the radiators are reaching the required temps and some aren't (this might...

But I wouldn't know...
