Hi , it sounds like your flue is sooted up . this is one of the things associated with solid fuel and they need regular cleaning. Call he installer and ask for a service . I wouldn't recommend doing this yourself
Should I shut down the boiler, or let it burn out? There is a warning sound and a rattle at the back of the boiler.
We have a service due next week. This boiler does central heating and hot water for a pub and our large house - there is a second which is going ok. I am just worried about keeping it going - is it dangerous?
I see you are offline. Please email as soon as you are back. I keep having to go and check the boiler.
Hi , I would shut down the boiler or try to get your service guy to come earlier
