I have a problem with my BAXI boiler. When the water is on, heating off, the water and heating come on, and when the heating is on, water off, the water and heating come on. Also, strange bubbling noises come from the header tank. This is worrying so i have turned it off!
Any Ideas to what is the problem? Does anyone have an online wiring diagram? Please send me the link so i could print it off? Thanks Mark

Paul..How many volts do you expect? 240 is what it should be!! Its a boiler not a torch.
