Hello everyone,
I had a consultation last week with a prefab house provider.
Of course, we also discussed the desired energy efficiency class for the house.
KfW55 is basically standard for prefab houses, and KfW40 is quite easy to achieve. After all, the houses basically consist of just a few wooden beams and insulation material.
Since I want to install a photovoltaic system on the roof anyway, it quickly leads to KfW40+.
My plan was to aim for KfW40+ with a solar system, an air-to-water heat pump, and underfloor heating.
My advisor now suggested an alternative: instead of the air-to-water heat pump and underfloor heating throughout the house, use infrared heating panels. This would save the costs for the heat pump (including maintenance) and underfloor heating. KfW40+ would still be achievable since the insulation stays the same and the heat energy is generated by the photovoltaic system.
I unfortunately forgot how the domestic hot water would be heated (I think either purely electric or with additional solar thermal).
A rough calculation showed that there would be no big difference in total costs. However, with infrared heating, maintenance costs and wear and tear would be eliminated.
Has anyone had experience with equipping an entire house with infrared heating?
So far, I only knew about it being used as bathroom mirrors.
Oh, and this manufacturer was recommended to me: try googling "Infrarot Riedlingen" 🙂

That's true. For every use case or idea, there is usually a corresponding horror story, and often everyone defends their own preferred model.Thanks for that! There are several systems for good reasons. Just because I don’t want underfloor heating with a heat pump doesn’t mean the system is bad. It simply doesn’t fit my requirements, preferences, and ideas. Plain and simple. For other families, this solution is actually ideal. Putting economic calculations aside for a moment, underfloor heating produces a different kind of warmth than an infrared panel. Different doesn’t automatically mean better. I know people close to me who struggle every winter during the dark season to maintain their mood, energy, and performance. Two things help exactly these people: light and warmth that they can actually feel directly on their body.

There are several systems for good reason.That alone is what I want to convey with some of my posts, and some people make their decisions less based on calculations and more on personal feeling. For us, it was clear from the start, for example, that we would have a solid plank floor and no underfloor heating, although I did consider it. Still, I can understand other choices just as well. hampshire schrieb:
The fact that I do not want underfloor heating combined with a heat pump does NOT mean that the system is bad. It simply does not fit my requirements, preferences, and ideas. Plain and simple. For other families, this solution is absolutely ideal.That’s exactly how I think, and it’s no good to rigidly support one thing while simultaneously devaluing another. It should suit your own lifestyle, which for us differs from the "typical" family life just as much as our approach to indoor temperatures does. What surprises me, though, is that despite human diversity, sometimes little individuality seems visible in house construction. I always find it interesting when someone does something different and I’m curious about it. hampshire schrieb:

Different does not automatically mean better.Currently, with underfloor heating, I often have to "air out" the warmth when the temperature changes (I picked up this term here in the forum 😀), which is probably due to the system’s sluggishness that I find unpleasant. That’s why I would have alternatively chosen heating with nice radiators. We are definitely planning to install a panel radiator on a wall that you can sit close to. Whether that makes sense technically or according to calculations? I have no idea... but it’s nice!
A bad planning decision only occurs when it doesn’t fit your own way of living.

Yes, that could be an idea. But you would probably need a power outlet for that? In our bathroom layout, there really isn’t any suitable space for it.Infrared panels are available in mirror form. You could use the power supply from the light behind the mirror or from the outlet for the shaver socket and replace the mirror with the heating element.

Not directly from the burner, since it would turn on and off with the light all the time.So, it’s controlled as needed? That’s great!H

Not from the heat source, otherwise it would constantly turn the light on and off.No, that can be solved. The switch will be converted into a wireless switch for the light, with continuous power supplied to the infrared panel, and control managed by a wireless thermostat.Similar topics
