I have an old Vaillant combi bolier, I think it's a VCW 242 EH which in general has given me little trouble. Over the last few years though it has started losing pressure and has got to the point where it's a real nuisance and needs topping up every time it's used.
It's been suggested that the problem is most likely to be caused by the expansion vessel and I further understand that there are likely to be two possibilities .. either it can be repressurised or I should fit a standard 12 ltr vessel to the heating return pipe near to the boiler.
Is there anyone who'd be interested in quoting for the above?
