If I have underfloor heating, whether the materials which is a better insulator on the floor (eg.a wood in relation to the ceramic tiles) affect on higher energy losses? Or the entire system will be more inert? It is assumed that the whole house is well insulated? I'm also interested in the same thing if the furniture is located in a place where it passes under floor heating pipes. Would it create a greater fuel consumption? Tnx for answers!
