My UFH under ceramic tiles runs at 50C +/- 5C and the surface
temperature is 26-30C.

You need to jack the water up a bit - I would have said 40C water would
be safe for wood as the surface will never get anywhere near the water
temperature.

I agree, it is great under ceramic tiles, also OK on carpet over
concrete. But personally I don't think I'd want to use it this way.
