I am thinking of replacing my old back boiler with a combi-boiler. I have a garage at the front of the house that is 1 metre away from the house and is connected via a porch. Can the boiler be sited in the garage with the flue coming out from the garage wall? I can insulate the pipes from the house to the garage to minimise heat loss.
PS The garage has a flat roof (could the flue go through the roof of the garage?)
