According to the district office, there is an issue with the building permit: the proposed location of the heat pump is not being accepted. The district office refers to a "guideline for improving protection against noise from stationary equipment."
Question: Has this guideline been legally established as binding in a law in Baden-Württemberg? In my opinion, the requirements are "can" rather than "must."
Specific details
Heat pump model: Weishaupt WWP L 12 AD
(According to my general contractor, Weishaupt does not offer a quieter heat pump.)
Heat pump location: See plan.
It should also be mentioned that this is a developed residential area, and the plot is a building gap. The buildings there were constructed in the 1980s/1990s. Accordingly, (oil) central heating systems are installed in the neighboring buildings, as there have been no new constructions. Therefore, there cannot be any heat pumps in the immediate vicinity.
Statement from the district office:
"If the heat pump were placed elsewhere, for example on the south side of the property, a greater distance to the neighbors would be possible. Due to the short distance to the house, reflections (within 3 m (10 feet) distance to a reflective surface) are to be expected. There may also be other noise sources in the vicinity."
"The planned location of the heat pump does not comply with the 'guideline for improving protection against noise from stationary equipment' in the following points:"
"According to the guideline, a maximum distance from and ideally a position facing away from the neighbors should be aimed for (see item 1 in the annex to the above-mentioned guideline).
"Given the tight building situation, internal or enclosed heat pumps, or heat pumps with significantly lower sound power levels, should be considered."
The unbelievable part:
The case officer at the district office even suggested to my general contractor that the whole house could basically be rotated so that the utility room (!) faces south, and then the heat pump location proposed by the district office on the south side would not result in long cables or pipes.
My reaction: "Seriously?"
Tomorrow I want to speak with the case officer myself.
Do you have any tips for how to proceed? Do you see good arguments I could raise?
Thank you for your input.

- Heat pumps must be installed according to the state of noise reduction technology in a way that additional noise emissions, for example due to reflections on walls, are avoided.

Do you have any tips for the next steps? Do you see any good arguments? If you somehow manage to install your heat pump at the planned location, this could open the door to future problems if it turns out to be too noisy. Therefore, my advice is to follow the recommendations from the local building authority and take measures to reduce the noise level:
- different heat pump
- alternative location
- enclosure
- gas condensing boiler
- ground-source heat pump
- ...
It will definitely be more expensive one way or another. But better to face a costly solution now than have endless problems later.
So, it’s a bit annoying when you hear a buzzing sound (like a refrigerator hum, but at a higher frequency) coming from a front yard several houses away during an evening walk through the neighborhood. Containing it sounds like a practical suggestion.

After that, a maximum distance from and ideally oriented away from the neighboring property should be aimed for (see point 1 of the appendix to the aforementioned guide). This should apply anyway for a good neighborly relationship.
Hello,
sorry, but the local building authority is right. With all due respect, the location you plan to place it in is really unfair to your northern neighbors.
You want to put the noisy device directly on the southwest side of their house, while for you it’s the hardly usable north side.
If I were your northern neighbor, I would already be consulting a lawyer.
If you really must have such a noisy machine, place it on the south side of your house facing the street. It will get more warmth and sunlight there and should operate more efficiently. So it’s a win-win situation.
Best regards,
Andreas
