I tiled over the Polypipe system a couple of times about 3-4 years ago. Decoupled and used Weber rapid spf with no problem. Fixed marble on both jobs

Beware that the size of one or more of your 4 floors might be at or above the limit for a heated floor without intermediate movement joints.

I tiled on this system end of last year .wunda under floor heating boards Maori 2 part adhesive as specified .the tiles still cracked and broke everywhere. But I done specifications to the letter

I am merely pointing out that UFH works best when the heat can be transferred uniformly to try and alleviate hot/cold spots which could, in theory, result in failures.
