everytime it gets really cold outside my boiler wont work it keeps starting up igniting etc then only runs for a few miniutes and stops.it only seems when its really cold my boiler is in the porch can anyone tell me if there is some kind of temp coupling that determines the outside temp its almost like it is wired wrong as it wont work when it gets cold????
I have the exact same problem. I thought perhaps it was because the boiler was having to work harder on cold days but sometimes the radiators aren't even hot, just luke warm. It's so annoying that it happens on the days you really need it.
