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?

AndreasPlü23 Apr 2017 21:08Of course, we will address this politely! So far, we have actually been getting along well. I just want to explore in advance which options we can discuss. Gabions? Wooden fence with infill? Does anyone have a sensible idea based on personal experience or professional qualification?
"4 m (13 feet), how can that be?" Well, it could also be 4.5 m (15 feet), but not more, since it’s a densely built-up area and the setback requirements are 2.5 m (8 feet) on both sides plus the distance to the house wall. Are there any legal minimum distances?

Hello,
Both, actually... The planner takes the easy way out and can offer a lower price. He doesn’t have to put up with the noise.
Without ruining the relationship with your neighbor, it will probably be nearly impossible—unless they are immediately willing to pay several thousand more for a proper system installed indoors. But then you’ll also lack the space, so that option is most likely off the table.
Noise measurements and protection regulations are complex, but here’s a very rough overview:
The system is only allowed to emit a certain noise level or create a certain noise exposure level at your property. The limits depend on whether you live in a purely residential or a mixed-use area and vary between day and night. This maximum level will probably be far exceeded by the system (like many others).
You could theoretically push your neighbor through noise reports and legal action to have the system relocated or replaced by a quiet heating system. However, this will take a long time and be expensive.
A gabion wall or simply using earplugs will probably be a better short-term solution.
Although building a gabion wall is not cheap either, and it’s questionable whether you’re even allowed to build one there.
Permanent peace will likely only be achieved through legal proceedings. But you probably won’t make any friends that way...
In extreme cases, it might make more sense to pay your neighbor to move the system. Better to spend €3,000–5,000 (or the equivalent) now than several times that amount in legal fees and create a lifelong enemy as a neighbor.
Best regards,
Andreas
