I have a valiant combi boiler, which works ok when hot water is needed, but the ignition light goes off each time central heating is switched on. Getting frustrated about this. Any advice would help, as a Central Heating engineer has failed me.

IF YOUR PILOT LIGHT IS GOING OUT SOUNDS LIKE THE BOILER IS OVERHEATING SEE IF YOUR PUMP IS RUNNING PROPERLY
