ᐅ Is it better to install the heat pump inside the house or outdoors?

Nowadays, there are almost inaudible units available, for example the Wolf BWL1-a.
What are your electricity costs (heating) like with your pumps?

To be honest, I’m interested in that too… costs and satisfaction.

Hello,
even though Bauexperte will probably call me too sensitive again:

If you really want to have such a noisy device, please be considerate to your neighbors and install it in the basement.

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

Tip: Take advantage of the last cold nights and walk through a new housing development. Then you’ll hear how loud split air conditioning units can be. And then reconsider whether you really want to subject the people you will be living house-to-house with for the next decades to that noise.

Best regards,

Now I wonder, are you familiar with the local conditions, meaning whether you yourself cannot hear the noise but others are disturbed?
And you write yourself, “take a walk on a cold night through a new housing estate…”
Who exactly would be sitting on their terrace next door on a cold night and be bothered by the unit? With the windows closed or in summer, the noise is usually barely or not at all noticeable.
Also, you can be polite and build everything as quietly as possible “for the neighbors,” but then you might be exposed to noise from two other neighbors.
Our neighbor has their outdoor unit on the side facing us, and we also have our bedroom on that side. With the window closed, you don’t hear anything, and even in summer when the window is open, it’s quiet.

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

Hi,

Who on earth would sit on their terrace on a cold night next door and be bothered by the unit? With the window closed or in summer, you can usually hardly hear it at all.

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

I was completely shocked a few weeks ago when I heard the outdoor unit from inside our locked car in the new development area. Luckily, it’s not a direct neighbor! Unbelievable..

I always say... This thing probably exceeds all noise limits, but what can you really do as a neighbor without starting a major conflict?
Our future neighbors have one of these classic examples. It sounds like all the bearings are shot; it rattles like crazy. Thank goodness it’s on the side facing away from us...

Best regards,

Andreas

Our new neighbor has a split system from Viessmann mounted on the exterior wall. Even below 0°C (32°F), it was audible but not bothersome—a faint noise at a distance of 3m (10 feet). It always depends on the location. In our case, the utility rooms are usually on the side where the neighbor already has a carport or garage, due to the connection situation.

Due to recent events on my end, I can only say that one should carefully consider whether to trouble their neighbors with such a noise source. There are good systems, large distances, and suitable plots of land. Wherever these conditions cannot be met, one should be cautious.

Such a pump also runs for several hours in summer to provide hot water and then operates at full capacity to maintain the supply flow.

In winter, with subzero temperatures, freezing evaporators, and heating demands, the situation does not improve.

In the worst case, your neighbor may file injunction lawsuits against you due to emissions.

Therefore, I agree with Uwe’s point: It depends on the location!
