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

Your considerations are generally correct...
An air-to-air heat pump works great... in Spain.
If you recommend someone to heat their house with a ductless mini-split system, they would likely be considered crazy... an air-to-air heat pump is basically the same thing.
However, the ventilation comfort should not be underestimated... once you get used to it, you tend to ventilate less by opening windows briefly... although you can still do it if you want.
My recommendation is simply underfloor heating combined with gas or an air-to-water heat pump as the energy source.

But an air-to-water heat pump has the issue of noise again, right? I have read a lot here about disputes with neighbors because the air-to-water heat pump runs at full power in winter and has to do so, otherwise it freezes. Also, you have the unsightly fan unit in the garden...
A gas heating system is at least relatively quiet, so I think I would tend to go for that instead.
What can you say about pellet heating?

Pellets require storage space, as they need to be kept somewhere...
I also chose gas... however, with gas, a renewable component is essential... such as solar panels or a controlled ventilation system with possible additional insulation.
As you can see, there is no single "right" heating system.
