After years of reliable service, our oil fire central heating has failed. My fault. I over pressurised the system – not that I should have been able to – by leaving on the refill tap to the closed system.
The water jacket (apparently) for the boiler sprang a leak and drained the entire system. The boiler it not made any more and there are not replacement water jackets available, so the whole thing needs to be replaced.
Getting this done before Christmas is not on. So it will be a cold holiday break.
