Somehow, we always assumed that underfloor heating is practically standard in new builds nowadays.
However, in the specification from Kern-Haus, we have now seen that this is not the case. Kern-Haus plans to install a Wolf gas-solar heating system "CSZ-2" and panel radiators.
Out of curiosity, we asked what it would cost to upgrade to underfloor heating for a house of about 150 m² (1600 sq ft), but we have not received an answer yet. We would also welcome any estimates or opinions from here 🙂
Personally, I am not really a fan of underfloor heating. We currently have it here, and I find it extremely difficult to find the perfect temperature. I prefer a radiator because I can turn it off or on exactly as needed. My husband tends to prefer underfloor heating.
Of course, radiators take up some space, and the appearance is a matter of personal taste.
Are radiators really considered outdated, or are there still others who could imagine having them in a new build?

Yes, that’s correct, as I already mentioned yesterday.
Whether I think it’s a good thing is another question 🙂 I have no expertise in this area, but if experienced people say that underfloor heating is better in terms of energy consumption as well, that is certainly a valid argument. Visually, it is also the alternative that is increasingly unavoidable.
However, so far we haven’t had a good experience with underfloor heating in our rental apartment, which makes me quite skeptical. It seems there just isn’t a single “right” temperature setting that regulates the temperature ideally. When the heating turns on, the room becomes warm within a few hours, but often too warm; the air feels uncomfortable and you really want to ventilate. However, opening the windows quickly lowers the room temperature, and then the underfloor heating kicks in again — making it even warmer. At least, that’s how a craftsman once explained the issue to us.

Visually and space-wise, it’s clearly the only option anyway.We deliberately chose flat panel radiators.
Because we don’t like or tolerate underfloor heating.
There would also have been significant additional costs.
It’s true that the visual argument matters – which we mitigated by placing the (now almost tiny in a KFW-70 house) radiators carefully. There is no spot where a radiator is in the way.
It’s also true that the gas boiler loses about 2-3% efficiency due to the higher required flow temperature. But so be it: It’s been comfortably warm here, and from August until yesterday we used about 340 cubic meters of gas for heating and hot water. The radiators, which I operate at a maximum low flow temperature below 50°C (122°F), provide a good, pleasant warmth. Lowering the temperature is possible, but I try to keep it minimal as it doesn’t help much.
It’s also true that underfloor heating would be wonderful in the bathroom; I decided against it back then due to double load and extended construction time.
The floor temperatures in our house, with room temperatures around 21.5 - 22°C (70.7 - 71.6°F), are everywhere between 20.5 - 21°C (68.9 - 69.8°F) (measured with an IR thermometer). There’s no question of cold floors; if floors were that cold outside, I’d walk barefoot already. Residents and guests feel very comfortable in the house.
Even if it’s unfashionable: I/we would choose flat panel radiators again, not underfloor heating.
An individual decision – against trends, against the mainstream.
Let’s leave it at that.
