Alternatives to outdoor installation of an air source heat pump

It looks something like this

Something like that... but it can also be a bit more compact :D

For example, if the outlets are planned directly around the corner of the house, you usually don't need any ducts like those in the picture.

I don't have another picture on hand with the built-in condition. You know the towers with the air intake/output from the manufacturers, but it's no use if you still don't know how it looks in the end.

But everything can also be a bit bigger :D depending on who you get.

Our "Tecalörchen," once inside, and once how it looks from the outside. For us, the supply air was routed over the carport because we didn't want a huge hole in the front wall of the house.

It's quite a beast. It wouldn't work for me. I need the separation of the units...

Yeah, and at the time the photo was taken, the ventilation system was not yet connected. There are still insulated pipes running along the ceiling (where you can see this hole).

So ours is the IDM ILM 2-7. It is somewhat larger than a large freezer. You don't see any ventilation ducts because the wall openings are directly at the wall. The water reservoir is just separate. But in 5.5 sqm, I don't think you can fit an indoor installation. I have to say, I do have some doubts that the "normal" technology fits in so easily. What else should go in there? Washing machine? Dryer? Connections? Power distributor? There are also distances that must be maintained...
