Infrared heaters throughout the entire house?

What was the name of the construction company again that suggested this to you? Underfloor heating is now common not only because it saves energy but also because it is spatially very comfortable since you no longer have disturbing elements on the walls. I also once considered infrared for spot heating, but I think it is a misplanning for more, especially in the new construction sector as the main heating system.

I have to clarify once again: This was not recommended. The standard usually installed would be a gas condensing boiler and underfloor heating or an air-to-water heat pump and underfloor heating. That is all great. And these are also the two technologies I would focus on. Toward the end of the consultation, however, we talked a bit about cost-conscious building. And also about what possibilities exist to obtain full KFW funding. And infrared heating was mentioned as one possibility to achieve KfW40 or KfW40+ standards while having comparatively low investment and maintenance costs. But only for the sake of completeness, not as a recommendation.

I honestly doubt that this will work with the KfW. The primary energy demand is likely to be terrible with pure electric heating.

Nothing, but I also know some here and various endless threads that are not so happy with their heat pump without a fireplace and have high bills.

If we were to install a heat pump when changing the heating system, we would certainly belong to that group, even though we have a fireplace.

My acquaintance with his heat pump is just annoyed and has been tinkering with it for 2 years or paying stupidly for maintenance costs.

I have also heard of such cases. However, I also hear this from "risk-takers" who have a pellet heating system as their main heating. Some have been satisfied for years, others constantly have problems. Of course, the "problems" cannot be generalized, as for example, the wrong pellets can already cause problems.

I understand it as follows:
...

Yes, it requires a certain "intellect" here and there to understand the texts from :)

...
A heat pump is extremely sensitive and makes a lot of trouble if in doubt, either it does not get warm or the efficiency drops drastically.

Didn’t recently report such problems in the bathroom and bedroom?

With a heat pump, it all depends on the skills of the heating installer and unfortunately also the client. The heating installers could install standard underfloor heating bluntly for years and decades without causing major problems. Gas and oil heating systems were also inefficient with poorly designed underfloor heating, but this did not result in such high costs. At least not directly.

With the heat pump, a room-by-room heat load calculation including an adapted design of the underfloor heating must be carried out. Then the heat pump must be properly initially set and the user instructed. Unfortunately, many of the heating installers are simply not capable of this. But they do not admit it. If the requirements are met, you usually have a low-maintenance, comfortable, and cost-effective heating system.

I wouldn't call it problems, I would build again with an air-to-water heat pump at any time. It's just that the fine-tuning still needs some work. But that's a personal preference, as I would like it a bit warmer in the bathroom.

But that is a personal preference, that I like it a bit warmer in the bathroom.

Maybe that could be achieved with an infrared heater.
