Reversible Air-Water Heat Pump vs. Air Conditioner with Heating Function

Ok, great. Thanks again for the numerous information and your help with this. I will probably look into getting an air-to-air heat pump or an air conditioner together with underfloor heating (for the winter). I now feel confirmed and don't like that everyone always tries to "push" an air-to-water heat pump on me.

Thanks for the hint and I know what you mean. However, the last two summers we had 6 weeks straight between 30 and 40 degrees. Of course, a maximum of 6 weeks is no comparison to 6 months or so, but I simply find the air from an air-to-air heat pump more pleasant because I don't put it on frost mode, but if needed, I could at least set it this way compared to an air-to-water heat pump. Especially when I imagine that with room temperatures of 28-29 degrees like now, the food (sweets) in the cabinets is melting, I think I prefer an air-to-air heat pump after all.

How is the water for the underfloor heating supposed to be heated then? The air-to-air heat pump (Luft-Luft-Wärme-Pumpe) cannot do that, can it?

First, take a look at the prices called for your planned solution. I think after that, a wall bracket or ceiling cassette of an air conditioner won't bother you anymore.

: As I said, I am a complete beginner. That is why I am very grateful for your experience and what options I have for the heating. Let's assume I go with the air-to-air heat pump. Do I then automatically also need radiators or what can I best combine with it?

: I just found this information. Are the price ranges correct?:

[*]simple central exhaust air systems: 2,000 to 3,000 euros
[*]exhaust air systems in combination with a heat pump: up to 13,000 euros
[*]supply and exhaust air systems including heat recovery: 4,000 to 10,000 euros

Or what costs would I roughly have to expect for the purchase?

These are prices for a residential ventilation system, that is a controlled residential ventilation; you cannot use it for air conditioning.

If you want to heat and cool with a central air-to-air heat pump, as you have already recognized yourself, you need a system to distribute the warm air in the house.

You should best search for central air conditioning and duct system.

Then search for air conditioning and ceiling cassettes or wall outlet.

Also consider that you need suspended ceilings and more room height for this.

This gives you a first impression.

However, it is important that your house or the heating load of your house matches this.

An air-to-air heat pump only works effectively and cost-efficiently if the heating load is low.

Hello, I am reopening the topic and asking the creator how he finally solved it and whether he is satisfied with the solution after this time. I favor a similar solution but have some concerns that, for example, one might feel an unpleasant draft from the ceiling cassette units.
