I am interested to know your opinions on the two ventilation systems, and whether anyone is currently using one of them.
Additionally, I would like to find out if investing in a decentralized ventilation system is a waste of money, and whether the heat exchanger provides significant energy savings that I can consider in my cost calculation. Thank you for your input.

Search for the thread about the Lunos e2. There was a pretty detailed discussion about decentralized ventilation. We have one now, and I would never install it in my own home. If you can’t hear it, it has hardly any effect; if it is supposed to actually ventilate the rooms, it is at least as loud as bathroom exhaust fans in windowless bathrooms, often even louder. That has been my experience with it.

That’s basically my experience with it. But you do realize that Lunos® offers different types of ventilation units and that landlords usually focus more on their returns than on the comfort of their tenants?

Lunos e2 is just Lunos e2 as far as I can see; these are complete systems, and that’s also what two of the general contractors we considered as finalists offered as their standard solution.
In our area, several people are building, and everyone who has dealt with the topic of controlled residential ventilation has opted for a central system. The pros and cons are all discussed in the thread. If you’re exploring this topic, you should evaluate the factors, for example by listening to a test installation, and then make your own decision. The choice between these two types of systems is not just an economic one. Whether the noise level bothers you and the open-window effect on acoustics are individual considerations.

By the way, it is a central system with heat recovery.
For us, only a central system was an option.
The ventilation unit is installed space-saving on the ceiling in the utility room.
