Hello everyone,
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.

Caspar202015 Mar 2017 17:44@smartsurfer: Honestly? I’m completely on the side of the local building authority. It seems that, on one hand, you have placed the equipment very close to the house; and at the same time, there is very little distance to the neighboring property. It doesn’t matter at all how far the neighbor’s house is from the boundary.
If there is no space structurally, then there is no space structurally.

The trend of designing heating systems by placing a separate noise nuisance module in the front yard, in my opinion, is nonsense that distorts setback regulations. I am grateful for every local authority official who does not allow this.
Fifteen meters (50 feet) and densely built? – “I wish,” I would say: I would argue for fifty meters (160 feet) instead, toward a row of undeveloped plots sloping slightly downhill toward the pedestrian. From that distance, I thought a kind of "transformer hum about to fail" must be coming from one of the streetlights. Approaching a single-family house, the culprit revealed itself as a bulky unit the size of an air conditioner.

I was walking through a new housing development over the weekend, and there were heat pumps that I could still hear from 15 meters (50 feet) away. In such a densely built area, I would not install a device like that.

Which direction do you plan to position the heat pump? Our heat pump can only be heard from the direction it blows air. From all other directions, it is hardly audible. Therefore, it should not blow air towards the neighbor, and apart from the side where it needs air intake, I also think placing it in a courtyard is a good idea.
