Hi, I'm renovating and extending an old brick built house. It is presently gutted, ie all plaster, joists, rafters removed, the plan is for underfloor heating in one room, 13 or so radiators, 1 family bathroom, one en-suite and a downstairs cloakroom. It is a blank canvas as far as plumbing is concerned, so before I start getting quotes I would like to have an idea of what I want. Do I need a convecting boiler? Is there a preferred type of underfloor heating? Any comments much appreciated, Cheers, John.
