My house is heated by a combi which is installed in the downstairs loo. The loo itself has no external wall, so the flue goes via a small adjacent lobby to the outside (it's boxed in, about two metres long altogether). A visiting builder has told me that when I come to replace it (hopefully a good few years off) new rules mean I'll have to get building control in from the local council who will tell me where I'm allowed to put my new boiler, and it's current location will not be an option. I think he's suggesting that it has to be installed on an external wall.
Is this right? It will be a pain in the arse to put it anywhere else and could involve some major dispution to the plumbing. If this is true I'm thinking of relocating it now while I've got some work going on to save disruption in the future.
