Heat pump directly next to the bedroom window

I find 13m appropriate then. If there are problems, a sound insulation can possibly be added later.

Just not into the own bedroom ... For this reason, I didn't want any . The noises are annoying .... Our is now in the living room, inside it is tolerable, outside annoying, but in winter you don't hear it that much .... 13 m are great, the neighbor can't hear anything anymore.
