ᐅ Underfloor heating in a concrete slab – advantages and disadvantages?

At the moment, I mainly think of disadvantages:
- Repairs and similar work are quite complex
- Cables, etc., cannot be installed above the concrete slab
- Heating the rooms is slower
Perhaps one advantage is that installing underfloor heating in the concrete slab might be somewhat cheaper?
It is reportedly quite popular in Scandinavia, partly because of lower residual moisture since there is no screed layer. But otherwise, does anyone know of clear benefits? Or do you even have practical experience with this?

My concern would be about sound transmission. Sound insulation is definitely worse compared to a floating screed installation. Wasn't there recently a discussion about sound transmission where the screed was not floating?
With a standard floor panel construction, you can achieve Passive House standard, so there is no need for a plywood subfloor.
Was Nordlys panel flat enough for the floor covering without having to apply large amounts of leveling compound?

Regarding the level. Yes, they really did very good work.
As for moving in, yes, people have moved in and at least they don’t complain about cold feet. It’s important to know that screed is a type of concrete. The traditional underfloor heating warms this. The Swedish panel heating warms the slab instead. Apparently, it doesn’t make much difference.
Another question: Do you even have companies down there in the Berchtesgadener Land (BGL) area that do this kind of work? Here in Schleswig-Holstein (SH), we are close to Sweden, so there are many Swedish house suppliers using such floor slabs, but what about where you are in Bavaria?
