Underfloor heating in a timber-framed house?

Hi, yes, it appears very flat. There is a video on YouTube that shows everything very nicely. I could imagine installing the distributor in the hallway, with extra insulation and decoupling. But I’m not sure if that is okay. Also regarding moisture, which is quite present due to liquid screed, but there is a kind of foil that is laid down beforehand. My second choice seems to be Uponor, I guess that no matter which system you use, you also have to shorten the doors at the bottom, right? I have been trying to find craftsmen for a few days now, but I probably chose the wrong time. Neither by email, fax, nor phone. Doesn’t matter, eventually I have to find one. I also have to clarify which heating system, especially which subsidies (grants and lower interest rates) are possible. There is a lot to do... and I am looking forward to it. So if anyone has these underfloor heating systems in use, I would appreciate information. Regards MaHaus

Something different. I assume the house is not particularly well insulated. Does it even make sense to work with low flow temperatures in that case? I'm afraid you won't really get the place warm like that...

Insulated is, that is certain, just not on the outside.
