The Zehnter is probably the quietest at the moment. But I think in the rooms it then depends heavily on grids, etc. I don't believe there is an extreme difference there. Except if the system always has to run at a high level because it is incorrectly designed or set.
We have installed the Zehnder Q350 and it is almost imperceptible. The installer was not familiar with the device and was very impressed by it. For me, it was mainly about the enthalpy exchanger as well as the possibility to integrate the device into KNX. I have nothing negative to report so far.
Anyone had good experience with moisture recovery?
I’m still uncertain
We have the Zehnder Q350 with an enthalpy heat exchanger. We are completely satisfied, the air quality is top. I would always prefer this over a regular heat exchanger!
If it should be quiet then Zehnder, tip: Air inlet in the floor exhaust valves in the ceiling Place the inlet and outlet on the outside on the east or north side. Not on the west side
