Hello, I’m Matthias,
I am currently in the final stages of planning (hopefully soon submitting the building permit).
I want to build to the KfW55 standard, which requires a controlled residential ventilation system. But primarily for comfort reasons!
At first, I quickly considered Helios, then Zehnder... shortly after that Komfovent. And so it went on from brand to brand. Since this is a major cost factor, I want to do everything right and take some more time to consider your experiences as well.
What is the best way to proceed? How do I decide on a manufacturer? Where should I start?
Which criteria should I consider besides the following?:
- Operating noise (I am very sensitive)
- KNX integration
- Intelligent, room- and demand-based control (VOC & humidity)
- Cooling/air dehumidification in summer (via earth tubes around the house/basement + heat exchanger in the supply air)
- Good accessibility for cleaning
//Key data\\
160m² (1722 ft²)
2.5 floors
3 bedrooms + 1 bathroom + 1 toilet
Open plan living-dining-kitchen area
Basement
Underfloor heating (gas)
That’s a lot of questions... I didn’t want to scatter this piece by piece. Any constructive advice is welcome.

Noise levels in rooms result from airflow speeds and how the vents are connected.
It’s like a fan: if it’s small and fast, it will be louder than if it’s large and slow.

The position of the valves in your setup is completely off; I would do it this way. There are planning tools available from, for example, Zehnder. Halmi, I would have liked to use Zehnder’s planning tool. Unfortunately, as a private individual, I don’t have access to it. It wouldn’t be a problem if I had an HVAC technician here who still had capacity. I’m stuck and time is running out.
