SIGNS IT IS NEAR THE END
1
One fault in a decade is bad luck. Two or three in eighteen months is the boiler telling you something. Add up what you have spent over two years before you agree to the next repair.
2
Once a model is obsolete, a repair can mean days without heating while a part is chased. If we tell you a part is no longer made, that is not a sales line, it is the practical end of that boiler.
3
Kettling usually means scale or sludge in the heat exchanger. Pressure that will not hold means a leak somewhere or a failed expansion vessel. Both are fixable, but on an old boiler both are also a sign the system is tired.
REPAIR OR REPLACE
Under 8 years, first real fault
8 to 12 years, repair is small
Past 10 years, repair is a third of a new one
Parts no longer made
