The boiler is a sime friendly (i feel they could have chosen a better name).
Sorry if I wasn't very clear in my message, If I have the thermostat up high for the central heating and the hot water running I don't get the problem. But if I have the thermostat right down and the hot water running...
I am having problems with my sime combi boiler.
When ever I run hot water for more then five minutes, the pressure drops and the pilot light goes out.
However the pilot light does not go out if you have the hot water running and the central heating running at the same time.
I keep having to...
