ᐅ Sound barrier wall for neighbor’s heat pump

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?

However, there is a significant difference between being required to connect to a district heating system and certain house types (semi-detached houses) having to share a heating system.

District heating would be a good option. However, as far as I know, it is only available in Flensburg here. We do not live in Flensburg, so it is not an option for us.
Otherwise, I don’t share 11 ant.’s view on the heating. Factually, he is correct. But personally, I think everyone has their own preference. Karsten

No, from a socio-political perspective, we need to stop burning or wasting fossil fuels and resources so freely. Instead, we should use the existing resources more efficiently.

Nobody wants, for example, nuclear power, so it has to be renewables. But nobody wants power lines, biogas plants, or wind turbines near their own property.

@Nordlys also chose gas because it is the cheapest way for them to heat their home.

That’s fine for them, but from a socio-political standpoint, it is not the right approach to successfully implement the energy transition.

Similarly, I am critical of the urbanization of agricultural and green spaces. Sure, everyone wants a house with a garden. But soil sealing (land take) is significantly greater than if modern urban planning is implemented.

I couldn’t have said it better myself:

Who then owns the system? Who is responsible for maintenance and replacement? There are also people who want a semi-detached house but not a homeowners' association (HOA) ....

It belongs to the association of its operators and users. This can be set up as an association (not necessarily registered) or as a cooperative—just as examples. Shared ownership of the property at the installation site is not required for this.

This is more decentralized than connecting to a facility serving an entire neighborhood—not only administratively closer to the users but also because energy savings are linked to avoiding transmission losses. Therefore, it makes sense to choose the scale of aggregated consumers so that an optimal operating point is “just” reached—while for a neighborhood system, it is already exceeded and the overall efficiency is weakened by transmission losses. Additionally, you can opt for different energy carriers nearby: for example, the neighbor on the left with carrier X, the neighbor on the right with carrier Y. In this sense,

it makes a difference whether you take district heating from 2 km (1.2 miles) away or local heating from 20 m (65 feet) away on the left or right.

So: although the tone could be friendlier, thanks for your input and explanation.

Ok, to put it differently:
Why do two houses have to share one heating system just because they share a common wall (semi-detached house)?
And in contrast, two houses that are 6 meters (20 feet) apart (detached houses) don’t have to.

From a societal perspective, I agree with you, but the special treatment of one house type seems ridiculous.

a) because their close proximity makes this inevitable.

b) combined with the "special treatment of one house type" regarding the shared boundary distance, this is not unreasonable (?).

And: at some point, you have to start taking some practical steps if you want to achieve results.
