ᐅ Height of floor construction with Vallox HRV ducting questionable

Good morning,
Yesterday, I was able to inspect the first pipes and distribution boxes of our Vallox controlled residential ventilation system.
What I definitely hadn't realized is that there is hardly any space left for the screed. Until now, I thought flat ducts would be used.
The current distribution boxes are about 17-18 cm (7-7 inches) high, and if the underfloor heating and screed are added on top, the planned total height of 20 cm (8 inches) won't be achievable.
Does anyone have benchmark values? What is the minimum thickness required for the screed layer including underfloor heating?
I attached a photo from the bathroom on the upper floor. The two distribution boxes are quite close to each other. Is there still enough space above the box and piping for underfloor heating pipes including the screed, or will there be no underfloor heating installed there?

Just some food for thought:
Even if the planning and compromise are really not ideal, could the cabinets possibly be hidden under the bathtub or shower tray?
The bathtub might then no longer be fully supported on the concrete base.
Is there not a drywall installation system that could be used?
For example, extending the bathtub or the toilet?
Where will the heating circuit manifold be installed?

Holy moly.
I can only advise you that the distribution boxes should definitely not be placed on the floor.
I don’t understand why Vallox doesn’t warn against this.
I have the same boxes mounted on the ceiling in my utility room. Since Vallox doesn’t offer a proper cover, I am currently having one custom-made.
These boxes are meant for maintenance (hence the access openings) and should ideally be left exposed. Of course, you can clean through the other openings, but then you’ll have dirt and technicians in every room.
To me, the boxes don’t seem particularly sturdy either. Having such a large hollow space with a narrow frame in the ceiling wouldn’t be ideal.
