I am looking to lay under floor heating in my bathroom.
The floor is just wooden floor boards and I plan to lay insulation/backer board, screw down and then lay the loose electric cable. I will then tile with a porcelain tile on the floor.
My question is what is the recommended thickness of insulation board to lay in order to achieve a good U value and to stop heat escaping into the sub floor?
Also can I just hook wire this up to the live in the lighting circuit which is RCD protected?
Will heat transfer through an Italian porcelain tile ok?
