Hello,
We are planning to install a new floor on the second floor of a house from 1956.
The floor for the second floor consists of concrete T-beams, insulation, and a finish layer.
On top of this, we plan to lay underfloor heating and floor planks.
The construction is partially described in the flooring industry's publication 'Wood Floors on Floor Heating' (GBR edition 1:2003).
A moisture barrier is laid on the concrete floor, followed by grooved chipboard with underfloor heating pipes and heat distribution plates.
Gray felt paper is laid to prevent creaking. The wooden floor, consisting of Merbau planks 130mm, is screwed to the chipboards to create a floating construction.
The screws must not go through and puncture the plastic.
My question is whether this will work well without causing creaking or other issues in the future.
Chipboard has a relatively small expansion coefficient compared to the floor planks, which might cause the entire construction to warp or bend.
At the same time, the chipboard becomes extremely thin where the grooves for the pipes are made, and there's a risk the boards might crack.
Does anyone have experience or can give any good advice?

The flooring industry wants it to be installed on floor 2 as well.
Probably to prevent moisture from floor 1 from rising up.
Good advice can be useful to avoid trouble in the form of creaky floors,
otherwise, it's probably just about laying it out and accepting the situation
