Hello again. I posted on here a few days ago about my gas Vaillant combi boiler which decided to pack up on Sunday. I have since called an engineer out to take a look at it and he's advised me that I need a new expansion vessel. Because the boiler is 14 years old, he has said that I'd be better off buying a new boiler altogether rather than pay out £475 (his quote) on installing the new vessel. Since I am hoping to move house within the next year I don't want to splash out on a new boiler unless I really have to. What d'you reckon?
