Air-water heat pump behind carport

Hello, we are considering placing the air/water heat pump about 2 meters sideways behind the carport in our new semi-detached house (see view air heat pump blue box). The outlet side would then face the garden (see arrow) and thus not against the main wind direction. The minimum distance to the neighbor of 3 meters has not applied in NRW since the beginning of this year. It is still unclear whether a hedge or a wire fence will be placed to the right of the heat pump; possibly the heat pump could also be clad. Is our idea realistic in terms of implementation due to the noise development? Unfortunately, it is still an uncovered niche.

Don't put them anywhere you walk past dramatically. These things are so quiet now, you can hardly hear them, but cold air comes out of them, which is always annoying to get hit by.

Where do the others install their heat pump? The noise level is not so critical. Only the "cold air," as already mentioned, is not exactly beneficial for plants opposite it.

Unfortunately, we do not yet know where the neighbors will place their heat pump.

You are building a semi-detached house with apparently twin-like halves – with a joint general contractor or buying it from the developer?
I'm surprised that the question only arises for you here, or that the neighbor's solution is unknown...

Yes, we bought it turnkey. The developer originally planned to place the air-to-water heat pump in the garden because of the minimum distance of 3 meters to the neighboring semi-detached half. We informed the developer about the decree of the NRW Ministry of Construction dated 05/02/23, according to which the minimum distance of 3 meters is no longer mandatory. Now we are looking for an alternative location, see the illustration above. We do not yet have the neighbor’s contact details but they will surely become known soon.
