Hello everyone,
Since we are interested in building with Weberhaus, we are currently looking into different heating technologies. Weberhaus offers all houses with an air-to-air heat pump as standard directly from the factory. This is their standard system and is already included in the price. Weberhaus calls this the so-called "comfort heating technology."
What bothers me about this is that it is basically an electric heating system. The heat pump electrically heats the water and also the rooms via air ducts. These air ducts also have heating wires that can be activated if the recovered heat is not sufficient.
I wonder if this is the right technology for us. Here are some disadvantages that come to mind without having experienced the air-to-air heat pump in winter:
1. Air is a poor heat carrier. It cools down too quickly and hardly stores any heat energy. Water is better in this regard.
2. I imagine the air being very dry in winter?
3. Because of the air movement, I imagine there could be increased dust buildup despite filters?
4. The system seems to rely on, or even require, that I do not ventilate myself but leave it to the system? However, occasional airing out (through shock ventilation) is a comfort factor for me (bathroom, bedroom, kitchen, etc.).
5. Electricity prices have only risen over the years (which makes no sense, since we have enough electricity). If electric vehicles become widespread and the government raises electricity taxes similar to fuel taxes, that could be the end of electric heating.
6. Thinking about people who relied on storage heaters in the 70s and now cannot sell their homes, I get uneasy about electric heating...
7. Retrofitting the heating system later, for example to gas or water-based heating, seems likely to be very expensive since everything would need to be gutted.
8. The air outlet vents somewhat spoil the walls for me. Especially with patterned tile wallpaper, I imagine this looks unattractive.
The clear advantage is the price! It seems to be excellent. No other heating technology is available so cheaply.
What else comes to your mind? Do you have any suggestions for me? Of course, I am also interested in experiences from owners of such heating systems.
Good luck

Does it make sense to combine a gas heating system with photovoltaic panels? Weberhaus offers a solution combining both.
1. Thicker exterior wall for improved insulation
2. Photovoltaic panels on the roof
3. A 3 kW (kilowatt) battery storage system in the utility room for self-consumption of the generated energy
This package costs €15,000 and turns the house into a KfW 40+ standard building, which is also subsidized with €15,000. This probably makes sense with a heat pump, but what about gas?

The choice of heating technology for the new house was also the most difficult decision for me. Many "sellers" highly recommended the Proxxon air-to-air heat pump. At first, I was very impressed by the concept behind it. Well, in the end, I went with an air-to-water heat pump from Buderus combined with photovoltaic panels. But it was a gut decision after weeks of research on the web beforehand...
With an air-to-water heat pump, I’m worried about the noise level. These units tend to hum quite loudly in winter, and throttling them doesn’t make sense because it causes icing. There have already been disputes about this in my wider neighborhood. The air-to-water heat pump seems to be one of the loudest types of heating systems. Ideally, I would prefer a gas condensing boiler, but then I wouldn’t be able to meet the KFW standard. Arghh! The dilemma of choice.
I have looked at several different models, both with and without a split unit. Yes, there were some noises (felt like in about one out of ten cases), but I didn’t find them particularly disturbing.
In this matter, I think we are treading on thin ice, as noise perception is obviously subjective. Check out some hi-fi forums: one person swears by Heco speakers, while another finds them overly bass-heavy...
If you want absolute silence and don’t want to take any risks, then you shouldn’t choose a heat pump. As for me, I made my decision very quickly. And thousands of households (just take a look at a nearby new development area, every other house around here has been built with a split system) did the same. Can so many be wrong? I can’t judge, but just ask the homeowners or neighbors of those who operate an air source heat pump...
