Hi I am after some information about replacing my warm air heating with a combination boiler. I have a top floor flat (2nd floor) and has concrete floors I have had a plumber out who says that he has to chase the floor then run the pipes in conduit so the concrete don't eat away at the copper pipes. My main concern is that the boiler would have to go in the same place as the warm air heater so would it be ok to use the same place were the original flue went, this goes straight up out the roof.
Thanks
Thanks
