ᐅ Location of heat pump – ventilation duct closed window

Hello everyone,

The heat pump has been purchased (thanks for the great advice here!) and I have now received the details about the safety zone. I’m currently considering the installation location.

The ideal spot is near a ventilation grille with a basement window to the boiler room. If I remove the window handle, the installer would be willing to install it there. Ventilation shouldn’t be much of an issue (basements are rarely ventilated anyway, and if needed, ventilation can be done through the door to the garage).

However, I still have concerns about whether the refrigerant might still penetrate inside in case of a leak (the window is 22 years old, and possibly not very airtight). In front of the window, there is a drainage channel. If I cut it at a height so that the opening is below the window, then the gas should seep downwards in case of a leak and not enter the house, right?

Picture of my desired installation location:

Looking forward to your feedback.

Good luck

Sorry to bother you, but I wouldn’t place them in front of the shaft since there are plenty of other exterior walls where they could go...

Most likely, the pipes are intended to be as short as possible.

Yes, the ideal location for a heat pump is not an interior corner of the house. Both efficiency and noise emissions are better on a straight wall or even in an open area (although efficiency may decrease over time due to pipe length).
