Hello! My new 2 bedroom flat is fitted with underfloor water pipe heating system. Now I'm at the stage to choose the floor boards and have a few questions. I'm a complete novice in home DIY stuff, but I need some clues before I can decide what type of floor to buy and cannot trust sales people on this! 1. Do you have to have special floor boards if you have a underfloor heating system? If so, what is special about these floor boards? 2. I know there are floor boards that are laminated and there are real wood ones, and I can see why the real wood ones are better. However, within each type, what differentiates them as the expensive ones can be 10x more than the cheap ones? I don't want to pay for things that are "intangible". 3. I saw on one website that they have "engineered floors" which are laminated and layers are laid in different directions. Are these the ideal ones to have for underfloor heating? 4. Any other general advice are greatly appreciated!!!!
