Hello everyone
We are building a townhouse to KfW 55 standard. So far, we have planned to use conventional radiators, as we find their response time better. However, doubts are now arising about whether these radiators can even be used in a KfW 55 building or if there are any reasons against it.
Has anyone dealt with this or is knowledgeable about it here?
We are not fans of underfloor heating, but if there is no other technical option and someone can explain why, we would consider using it as a last resort.

Which ones?

Although we only have a gas boiler as well, I still have to wonder about the illogical choices made during construction. It’s as if building is a game where you pick different components at will, and the builder just approves it.
I mean, we’re not in a pizzeria where you customize your pizza according to your taste. Even if sardines and salami don’t go well together, you might try it once—and then order differently next time.
Off-topic: but salami and sardines actually go quite well together [emoji1318] I just had that on my pizza yesterday [emoji6] Surf and turf, if you will [emoji4]
On the topic: is gas chosen mainly for cost reasons or other factors? If the former, I would recommend recalculating all costs and comparing them with alternatives. I seem to remember that gas isn’t really cheaper than, for example, an air-to-water heat pump. Of course, you have to like the latter...

Hot feet are no longer an issue in new houses if the heating installer does the job correctly. The underfloor heating is designed so that the surface temperature does not exceed 32 degrees Celsius (90°F), making it unnoticeable on your feet.32 degrees seems quite high to me. I recall our builder mentioning a supply temperature of 27-28°C (81-82°F), which results in around 24-25°C (75-77°F) at the surface. That already feels quite cool, far from warm. I wouldn’t want it any cooler—meaning no underfloor heating—even though I don’t personally suffer from cold feet as much as is often said about 50% of the population. For me, underfloor heating is one of the biggest advantages of a new build compared to traditional heating in older houses. It doesn’t really save energy in our case, since the district heating system (unfortunately) supplies water at 70°C (158°F).

Could it be that your first sentence is jumping ahead and that you are actually still in a personal planning phase without having spoken to a builder or architect yet? That’s also the impression I get.

Allergy concerns? Other worries? I would actually associate those more with traditional radiators. They are prime dust collectors.

Yes, 32 degrees Celsius (90°F) is quite high nowadays if done correctly. Unfortunately, it is still often the standard.
And yes, radiators are worse for allergies. Dust on radiators heated to 55 degrees Celsius (131°F) is not healthy. However, there are also rumors saying that underfloor heating might be problematic in this regard.
But the original poster's question has been answered, and radiators seem to be the chosen option.

With these fundamental questions (similar, for example, to choosing between stone and timber frame houses, Ytong versus Poroton, etc.), it seems to me that a lot of "gut feeling" (myths and the like) is involved.
