Alternatives to outdoor installation of an air source heat pump

So I would definitely not want the device on or even in front of the terrace. House wall, roof, everywhere else.

According to the architect, this is not possible.

Hmm, it is still done like this daily worldwide...

Is there a reason why all exhaust directions are to the left or right? Not away from the house?

He doesn't want it to blow onto his terrace...

And I had already asked: why not towards the street?

The building envelope is already maxed out there, if the zoning plan even allows it, he would have to push the whole thing back by about a meter (thickness of the heat pump + 30cm clearance).

Which heat pump was planned as standard?
I can hardly imagine that wall mounting should be excluded.

@ : If the exhaust direction were to be towards the garden, for example, the device would have to be turned. However, the device is 1.2m wide and would then stand in front of the window. Of course, one could move the door here, but then doors and windows would be asymmetrical. Why is option 1 not a good solution? It is not possible towards the street, as it is explicitly excluded in the development plan. All attempts to talk to the office were unsuccessful.

@ : I am not familiar with wall mounts. But since the clearance areas probably also have to be observed here, only a mount on the back wall would remain. However, this would mean the device hangs directly in front of the children's bedrooms. Presumably, this is also not optimal.

@ : A Nibe f2120-12 is to be installed as standard.

Why is option 1 not a good solution?

Because KfW55 houses generally cannot be heated economically with it. This type of heating should have its sweet spot somewhere between KfW40 and passive house.
That is speaking generally now. What this model can do specifically (e.g. with the optional supply air) I do not know exactly.

Ok, according to the installation manual, wall mounting is really not intended. Which doesn’t mean it’s not possible, but the manufacturer at least doesn’t provide it as an option. Pretty stupid. I would then go for geothermal energy, I think.

Which variant for the installation of the external fan would be the best? I am well aware that none of the three are perfect.
