Hi I'm a qualified electrician which I rewire houses, wire y plan and combi boilers. I'm looking for information how a combi works. I have been on YouTube and looked at videos but don't give me enough information. I know that when you turn the hot water tap on, it gets water from supply from outside and it goes through the heat exchanger and goes out to hot water taps.
With the radiators it pumps water around the radiators to another heat exchanger.
That's all I understand, can anyone give me a simple video/website etc how how a boiler actually works please.
