Is the heat pump outdoor unit installed correctly?

For us, it stands on several palisade stones. Once during the construction phase and then later installed.

I'll put it this way.... whether right or wrong, it applies to everyone: it just doesn't work nicely ;-)

Tell me, the "finished" picture has already been shown here before. However, it was about dirty paving stones then. That was quite a while ago and you have only been here for 4 days. How does that fit together?

quite simple, I registered here a few days ago. What you mean was written in another forum. So you also hang out "somewhere else". ;)
