Drying tip for concrete before underfloor heating is started

[dare]

Hello,

I have just poured a 7 cm thick slab with quick-drying concrete indoors. According to the concrete company, I should be able to lay parquet on this in 3 weeks.

The construction is:
Old slab
Platon system
Styrofoam 8cm
Waterborne underfloor heating embedded in 7cm concrete.

How long must this quick-drying concrete dry before I can turn on the underfloor heating?

Calm down about 3 - 4 weeks. Gradually start the heating, i.e., increase a little at a time.
