There have been a couple of threads from me now since I tore up the living room and kitchen due to the installation of underfloor heating.
When we were about to plug the water hoses coming out of the kitchen wall, the VS guy raised his eyebrows.
It wasn't regular water hoses used when renovating the kitchen, but underfloor heating hoses instead.
This resulted in him not having the right fittings that matched, so he had to go and get new ones.
He suggested that it was actually dangerous to use these hoses since they are not made for tap water but for underfloor heating water.
Is it correct that they are dangerous in some way?

Could it be that they are not rated for the same pressure as drinking water?
You should be able to read the markings on your hoses and return with the information here so we can see what you have.
Edit:
Uponor's underfloor heating pipes are rated as PN6 (max 6 bar) and max 60 degrees, but their regular PEX pipes can handle 95 degrees temporarily and 70 degrees continuously, as well as 10 bar (PN10).
From Rinkaby's website:
Uponor Underfloor Heating Pipe PePEX Pipe 17 mm:
PePEX pipe 17x2 mm. Max 60°. Material consumption approx. 6m/sqm with c-c 200 mm. Pressure class PN6, oxygen diffusion barrier.
Regular PEX pipes
Uponor Combipex Pipe-in-pipe for cold water, hot water, and heating installations. With protective pipe made of polyethylene (PE). Max temp +70 degrees C, max temp momentarily +95 degrees C. Max pressure 1Mpa, Handles Q&E and FPL-PX fittings.
I don't think using underfloor heating pipes for drinking water is harmful to you, but rather that the risk of leakage is much greater.

Could be the plastic material as well, that it is not food-grade approved.
6 bar is probably a bit on the edge, unless there is a reduction after the water meter that ensures a lower pressure.
But why not ask the röris what he meant?
