Air heat pump with fireplace, water-bearing stove, hot water heating

Just the fact that this technology forces a neighbor to take action disqualifies it.

I mean, everyone should do what they like, as long as there is space. But just look at the new housing developments. 400 sqm blocks, all squeezed together.
Now if just one person sets up their system incorrectly, or who knows, these things get louder over the years... server fans and air conditioners do too
And there you go, trouble.

There are people who live by a highway, and it doesn’t bother them, but there are also people who hear a faint humming. I, for example, hear something like that and go crazy.
We have just recently built a new house, and it’s so quiet there that you could hear a pin drop. Luckily, I have 800 sqm around me free from any kind of technology. I would probably also be disturbed if such a thing was running outside my window.

Although with modern buildings, you don’t open the window anyway

... I can only advise everyone against installing such a noise-producing energy guzzler, unless you hate your neighbors. Wombel

A completely wrong conclusion! Especially "energy guzzler" is absolutely nonsensical! It is undisputed that air heat pumps cause a certain noise level. With an appropriate background environment, this usually hardly matters. In an absolutely quiet location, however, it does! Here you can choose indoor units, although unfortunately they are not fully modulating. In the outdoor area, fully modulating split units only cause corresponding noise disturbance at very low ambient temperatures, if at all. Unregulated evaporators, however, can indeed become a problem. In an absolutely quiet location, especially at colder climate locations, one should also refrain from air heat pumps in favor of ground source heat pumps. Here we are again dealing with specific, individual, location-specific boundary conditions. No construction project is like another. What makes sense in A is barely acceptable in B and leads to a money pit in C!

Good evening, my neighbors built the cabins for their retirement (I think more like an investment)... for in 15 years! That means they are there max on weekends, but the air heat pumps run around the clock and I am even on friendly terms with the neighbor opposite me. He even adjusted his air heat pump so that the noise no longer directly blasts onto my house front, I still had to hear and feel the noise even with closed windows!! Nevertheless, especially at night, the noise situation is impossible, because otherwise here at most the eagle owl hoots. The TA noise was created for industrial areas and is only a guideline, 35 db were measured in front of my window, so within the "standard values", that may only be the noise level of refrigerators, but please try to imagine sleeping in a room with a constantly humming refrigerator... 24 hours a day, for the rest of your life. Believe me, you don’t get used to this noise, it drives you mad in the long run. Now the neighbor wants to put up concrete L-walls, whether that really helps? ...what an effort for such a stupid heating principle... and if that thing runs day and night, it also consumes significantly more electricity than makes sense, how is that supposed to keep up cost-wise with my basket of wood??? ...I will use about €600 in heating costs (without water) for the entire year, my neighbor definitely won’t manage that, although his bungalow is about 100 m2... our house 110 m2. AND... they have definitely taken a massive piece of quality of life and I am no longer willing to listen to when the neighbors heat... so unnecessary.
