Is it possible to repair the heat excahnger - old floor standing Marathon
boiler which has evidently sprung a leak .. drip drip drip!!!
It's now not functioning.. so.. a new one for £800 ish or is it worth
getting someone to weld it - is that possible??

Dunno the Marathon, but old boilers usually have cast iron heat
exchangers made in sections with some form of gasket between the sections.
And it's usually this that fails. Whether spares are available and you
could find someone willing to fix it I dunno either.
