We've just moved into an aged bungalow and the existing open-vented CH boiler (a floor standing Potterton Kingfisher) is on it's last legs. The existing CH boiler is flued into it's own chimney stack.
The replacement boiler will be a wall-mounted condensing boiler and it seems sensible to me to reuse the chimney for the new (concentric) flue. However, BG say that all joints in the new flue must be accessible and therefore the flue cannot be housed in the stack as access to the flue joints at a later date would be impossible.
I'm intending to get some alternative quotes apart from BG but I'd like to know if my suggestion is a possibility, so does anyone know if this is a requirement by law, or is this just BG being inflexible?
