Heat pump: better inside the house or in the garden?

There are now really almost inaudible devices. For example, the Wolf BWL1-a. How are your electricity costs (heating) with your pumps?

Honestly, I would be interested in that too.... costs and satisfaction

Hi,
even if Bauexperte will immediately call me too sensitive again:

If you absolutely want to have such a noisy device, please be nice to your neighbors and have it installed in the basement.

Your architect’s planning already says it all: “planned behind a retaining wall in the garden.” So you don’t hear the noise yourself, but it doesn’t matter if you annoy others with it.

Tip: Use the last cold nights and walk through a new housing development. Then you’ll hear what kind of noise the split units can make. And then think again about whether you really want to do this to the people you want to live house to house with for the next decades.

Best regards,

Andreas

Now I wonder, do you know the local circumstances, i.e., that you yourself don’t hear it, but it annoys others?
And you yourself write, “walk through a new housing development on a cold night…”
Who, please, sits on the terrace next door on a cold night and is disturbed by the device? With the window closed or in summer, however, you normally hardly or do not hear it at all.
You can also be kind yourself and build everything “for the neighbors” as quietly as possible, but then you yourself get “sonically bombarded” by two other neighbors.
Our neighbor has his outdoor unit on our side and we also have the bedroom on that side. With the window closed you hear nothing, likewise in summer when the window is open.

The planning of your architect already speaks volumes: "planned behind a retaining wall in the garden." So that you don't hear the noise yourself, it doesn't matter if you annoy others with it.

I was completely shocked when I heard the outdoor unit from inside the closed car a few weeks ago in our new housing development. Luckily not a direct neighbor! Incredible..

Hi,

Who on earth sits on the terrace next door on a cold night and gets disturbed by the device? With the window closed or in summer, you normally hardly hear it at all.

There are supposed to be people who like to sleep with the window open even in winter... And then these things are really annoying!

I always say.... This thing probably exceeds all limit values but what exactly can you do as a neighbor without starting major stress right away?
Our future neighbors have such an absolute prime example. It seems all the bearings are broken, the thing rattles like nothing else. Thank God it’s on the side facing away from us...

Best regards,

Our new neighbor has a split unit from Viessmann hanging on the outside wall. Even below 0°C, it was audible but not unpleasant, a quiet rustling noise at a distance of 3 meters. It always depends on the position. In our case, the technical rooms are usually on the side where the neighbor already has a carport or garage due to the connection situation.

Due to the current situation with me, I can only say that one should carefully consider bothering their neighbors with such a noise source. There are good systems, large distances, and suitable properties. Wherever I cannot approve these points, one should be alert. Such a pump also runs for several hours in the summer for hot water and then at full load to manage the flow. In winter, with subzero temperatures, freezing evaporators, and heating demand, it does not get any better. In the worst case, your neighbor may overwhelm you with injunction lawsuits due to emissions. Therefore, I share Uwe’s point: It depends on the location!
