KfW 55 without underfloor heating

...
For us personally, underfloor heating has more disadvantages than advantages, also health-wise.

Which ones?

Although we also only have a gas boiler, I still have to wonder at the illogical way things are built. As if it’s a game where you pick and choose from several building blocks and the builder just approves it. I mean, after all, we’re not in a pizzeria where you can customize your pizza to your taste. Although sardines and salami don’t go well together, you can try it once; the next one will be ordered differently again.

Offtopic: but salami and sardines go quite well together [emoji1318] I just had them on my pizza yesterday [emoji6] Surf'n'turf if you will [emoji4]

On the topic: is gas chosen for cost reasons or others? If the former, I would calculate again, considering all costs and comparing with alternatives. I seem to remember that gas is not really cheaper than, for example, an air-to-water heat pump. Of course, you have to like the latter...

Even the hot feet no longer exist in new houses if the heating engineer works properly. The underfloor heating is then designed so that the surface temperature is a maximum of 32 degrees and you can no longer feel it on your feet.

32 seems quite high to me. I seem to remember that our construction company spoke of 27-28°C flow temperature, of which about 24-25 arrive at the surface. That already feels quite cool, anything but warm. I wouldn’t want it any cooler, i.e., without underfloor heating – although I don’t suffer from cold feet as much as 50% of the population is said to. Underfloor heating is for me one of the greatest advantages of a new build compared to traditionally heated old buildings. It doesn’t bring energy savings for us, since the district heating (unfortunately) comes in at 70°C.

Could it be that the first sentence is premature on your part and you are still in a personal planning phase, without having spoken to a builder or architect?

That is the impression I also have.

For us personally, underfloor heating has more disadvantages than advantages, including health-wise.

And what would those be?

Allergy issues? Other concerns?

I would understand those conversely for classic radiators. They are first-class dust collectors.

Yes, 32 degrees is very high nowadays if done correctly. But unfortunately often still the standard.

And yes, radiators are worse for allergies. Dust on 55-degree radiators is not healthy. But there are also rumors that underfloor heating is supposed to be bad for that.

But the question of the OP is answered and radiators seem to be set..

But there are also rumors saying that underfloor heating is supposed to be bad there.

Yes, rumors. In such fundamental questions (similarly with stone versus wooden panel houses, Ytong versus Poroton, etc.) it seems to me that a lot of "feeling" (myth & co) is involved.
