Can this system be used under wood or parquet floors? What is general application guidance?
Tiles, stone, slate or even engineered floor covering (like Pergo) are always great for floor heating. Wood, on the other hand, is an insulator and does not like to be heated. Constant heating would eventually drive out its natural moisture with undesirable long term results. Good hardwood floor is at least thick and often as much as or more. Thats too much for the radiant heat to penetrate it well and then still being able to heat the room and its occupants. Carpet with carpet padding are also not so good for radiant floor heating, because carpet is an insulator, thus by definition it prevents good heat transmission or conduction.
