Hi
I'm hoping for some advice on what to do next with a boiler problem we have been experiencing for the last month. We had a leak off one of the central heating pipes and had to shut off the CH to have it fixed. When it was switched back on the boiler wouldn't fire. The engineer diagnosed a faulty boiler thermostat. It's been replaced and the boiler will fire, but shuts down after the boiler thermostat temp is reached, but before our set room temperature is reached. The override light doesn't come on at all. I've never had to adjust the boiler thermostat before but if I turn it up now the boiler will run until the new temp is reached. The radiators have to become almost cold before it will fire again.
Since moving into the house 18 months ago we have had the boiler serviced twice and the zone valve replaced (I think that's what it's called!).
The two engineers who have looked at it recently have not been able to offer a solution. They have just noted that:
- the room thermostat definitely works and calls to the boiler.
- the zone valve is opening and closing as it should be.
- the pump is running, albeit continuously, which it apparently shouldn't.
We have a Grandee G7 boiler and plenty of oil in the tank.
Should I now call an engineer to check the pump?
Thanks
Jen
