Can anybody advise please? I have a conventional boiler and when you turn the hot water on the boiler fires up, however when i turn the heating on i get nothing atall not even a pilot light!
Can you give more info on boiler make and model. Have you made sure that no-one has altered the room thermostat etc, as the boiler etc is working okay for hot water. I would start by checking the 3 port valve and actuator.
