ᐅ Experience with Ventilation of Roller Shutter Boxes: Aereco Zuroh 100

Hello everyone,

In our house, ventilation units are to be installed in the roller shutter boxes in the four rooms in the attic—dressing room, bedroom, Child I and Child II—as well as in the kitchen and living room. Specifically, Aereco Zuroh 100 units. Does anyone have experience with these and can share their opinion? Are they worth it?

Our site manager says we don’t necessarily need them, but if we want them, they will be installed.

Why not just use window rebate ventilation then? It's at least discreet.

In my opinion, the vents in the roller shutter box are the better option.
Window frame vents have a smaller cross-section and are less effective.

No one has any experience?

We have had an Aereco roller shutter box ventilation Zuroh 100 installed in our condominium since May 2021. In winter, the humidity levels stayed between 23% and 27%, and I was only able to slightly increase it to around 35% by using damp cloths, which I had to replace constantly.
Low humidity is very unhealthy, and having wet cloths around the living area is not very appealing.
Now, I can’t get rid of the heat (25-26 degrees Celsius / 77-79 degrees Fahrenheit) inside the apartment, even though the outside temperature has dropped to only 17 degrees Celsius (63 degrees Fahrenheit).
Overall, I would never have something like this installed again. So far, I have always managed ventilation well on my own.

But this has nothing to do with the ventilation system.
