Hello,
We are currently building and during our last site visit, we made our first negative observation: Our neighbor has an outdoor heat pump installation with the exhaust facing directly onto our property, partially affecting our terrace.
The distance between the heat pump outlet and our house wall is about 4 meters (13 feet). It is a Viessmann V 200. Now we have a constant humming noise that can also be heard on our balcony, which is about 6 meters (20 feet) away in a straight line.
Why would someone do this—poor planning or cheaper than an indoor installation?
Seriously, my question is: Are there any products that can help with this? I am thinking of a soundproof barrier, for example a 2-meter (6.5 feet) high wall running along the entire boundary (about 7 meters (23 feet)). What recommendations or experiences do you have?

Regarding the noisy heat pump again. In my opinion, it is part of the main system, so the same regulations for setback distances apply as for the main building. Therefore, no construction within setback areas. Was this rule followed? Or is there an exemption in the development plan? Do you have a source for that? I don’t think that is the case.
Well, there is primary use, secondary use, and garage/carport/parking space.
The heating system is part of the primary use (residential) and is therefore not considered a secondary facility (e.g., swimming pool or prison – both not closely related to the primary use).
However, in my opinion, there are no court rulings on this yet, as it is a relatively new topic. So, everything I write here is about 50% uncertain…
I’m just saying, if the original poster wants to push the issue (which I do not recommend), they could also approach it from the perspective of setback requirements (building permit/planning permission), meaning it should first be reviewed by a specialist lawyer to determine if it’s a relevant topic.

This means that an air-source heat pump may not be placed too close to a neighboring property. The court decided that an air-source heat pump must stand 3 meters (10 feet) away from the property boundary (not just 0.5 meters / 1.6 feet) due to setback regulations defined by state building codes, as the heat pump is considered to have a building-like character.[/QUOTE]
If you search a bit more, you will find other opinions as well. It appears necessary to study the respective state building codes and development plans.

It seems necessary to study the relevant national building regulations and zoning plans.Moreover, your quote does not clarify whether it refers only to the outdoor unit of a split system or to a complete heat pump designed for outdoor installation.
