Hi could anybody point me in the right direction i have a crappy Britony combi se 80 boiler, and yes I've heard they are crap, my question is when trying to switch the heating off at the timer switch the heating stays on and the radiators are red hot, it also keeps firing itself up over and over again so i have to manually switch the boiler off with the switch on the front, I'm curious to know could this be a thermostat problem? please help because I don't have a clue about boilers, thanks in advance.
