Tiles on leveling floor

[Christian Ek]

Hello.
We are in the process of converting our garage into living space. It will become two bedrooms and a utility entrance (nearest in the photo). We have built up a leveling floor and will install chipboard flooring with underfloor heating (LK HeatFloor 22) in all rooms. In the utility entrance, we plan to have tiles, and when I read LK's instructions, it says to use LK Kiilto Floor Heat DF and a minimum thickness of 25mm.

Is it possible to use another flooring levelling that can handle a thinner thickness?

Is there anyone here who has done a similar project with tiles on a nivellgolv?

How did it turn out? Did you lay the tiles?
