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" 🙂

A 49-watt heat deficit means that, at the design temperature, there is 49 watts of heating power missing. For comparison, a tealight candle produces about 30 watts when burning. So, if it gets too cold during the deep winter, you can simply place two tealights on the edge of the bathtub :-)

So, controlled according to actual demand? That’s great!Yes, totally cool. Especially in summer, this feature will be much appreciated :phampshire schrieb:
No, that can be solved. The switch is converted into a wireless light switch, continuous power is passed through to the infrared panel, and control is handled by a wireless thermostat.True, that’s an option. Although I would only do that if I already had some kind of smart home system in use anyway.

Yeah, totally cool. Especially in summer, this feature will be really appreciated :p Is it really unimaginable that the device also has a switch? Admittedly, I didn’t check that on the device, but I think it’s quite likely that such switches exist.

Is it really so hard to imagine that the unit also has a switch on the device itself? Admittedly, I didn’t check this on the device, but I think it’s quite likely that such switches exist.There are plenty of devices that ALSO have a switch.A
