Give us a clue on the make of the boiler ???. Some combi boilers have a diagphram which turns on the boiler when you turn a hot tap on , these diaphragms split so the boiler doesnt fire up when you want hot water . Does the boiler do anything at all when you turn a tap on when the heating is off????
