Air-to-air heat pump experiences?

Hello everyone,

since we would like to build with Weberhaus, we are currently interested in the different heating technologies. Weberhaus! offers all houses with an air/air heat pump from the factory. This is the standard technology there and is already included in the price. Weberhaus calls this the so-called "feel-good heating technology."

What bothers me about it is that it is basically an electric heating system. The heat pump heats the water electrically and also the rooms via air ducts. These air ducts also have heating wires that can be switched on if the recovered heat is not sufficient.

I wonder whether this is the right technology for us. Here are some disadvantages that come to mind without having experienced the air/air heat pump in winter:

1. Air is a poor heat energy carrier. It cools down too quickly and stores almost no heat energy. Water is better in this respect.

2. I imagine that I will have very dry air in winter?

3. Due to the air movement, I imagine there will be increased dust formation despite filters?

4. The system seems to be based on, even requires, that I do not ventilate myself but leave it to the system? However, occasional airing out is a comfort factor for me (bathroom, bedroom, kitchen, etc.)

5. Electricity prices have gone only one way for years, up (which is completely crazy since we have enough electricity). If electric cars eventually come and the government raises electricity taxes analogous to the gasoline tax, this might be the end for electric heating.

6. When I think of the people who relied on night storage heaters in the 70s and now can't sell their bunkers anymore, I get uneasy about electric heating...

7. A retroactive conversion of the heating system, e.g. to gas/water, seems likely to be very expensive since practically everything would have to be torn open.

8. The air outlet openings somewhat disfigure the walls for me. Especially with patterned wallpaper, I imagine this looks ugly.

The advantage is clearly the price! That seems to be great. No other heating technology is as cheap.

What else comes to mind? Do you have any suggestions for me? Of course, I am also interested in the experiences of owners of such heating systems.

Best regards

There you have highlighted the only advantage

Yes, I think so too. I haven't found any others either. Are my disadvantages roughly correct? What kind of heating technology do you recommend to me? Standard gas-water with underfloor heating?

your considerations are roughly correct...

An air-to-air heat pump is great......in Spain

If you recommend someone heat their house with a split air conditioning system, they would be considered crazy...an air-to-air heat pump is basically the same...

However, the ventilation comfort should not be underestimated...once you have gotten used to it, shock ventilation takes a back seat...nevertheless, you can still do it...

My recommendation is simply underfloor heating with gas or an air-to-water heat pump as the energy source

But an air-to-water heat pump has the problem of noise again, right? I read a lot here about neighborhood disputes because the air-to-water heat pump runs at full power in winter and has to run, otherwise it freezes. Besides, you have the ugly fan standing in the garden...

A gas heating system is at least relatively quiet, so I think I would tend to lean towards that.

What is to be said about the pellet heating system?

For pellets you need space, because they have to be stored somewhere...

I also chose gas... however, with gas you absolutely need a renewable component... like solar stuff or controlled residential ventilation with possibly extra insulation

You see, there is no "right" heating system
