Hi,
We've got a baxi bermuda 552 back boiler. We had a gas engineer visit today to give it a service and he's issued us with an "At Risk" notification on it. He's said the boiler needs replacing - he doesn't supply / install boilers himself so there's no gain in him recommending replacement (and he didn't even charge us for the abandoned service).
A new boiler is expensive - even replacing the baxi with a similar model is 600 excluding installation - so I'd like to see if repairing it is feasible.
The diagnosis is the burner assembly is rotten caused by combustion chamber leaking. I've removed the boiler covers and confirmed this. In reality the boiler seems to be very simple - Is it feasible to just replace the chamber and the burner, or am being over simplistic? When cold there's no water leaking - what normally causes a chamber to leak.
Advice please - It's damned cold!
Steve.
