Hi, I have a combination boiler, that is used for the central heating system and for heating water for domestic use. And I am quite clueless of how the system actually works.
My query is that, if in an emergency I need to turn off the mains water supply, do I need to also turn OFF the central heating/hot water (boiler)? Can any damage be done to the boiler if no water mains is available?
Many Thanks in advance.
