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.

"Exhaust air to the outside" is referred to as "exhaust air."
"Supply air from outside" is called "fresh air."

One more tip: the Zehnder q350 is a very good model. Take a look at it. I actually only know satisfied customers and have installed it myself.Fully agree!!

Be careful that too much air does not flow through a valve or a pipe.
A slower airflow is usually also a quieter airflow.

I am not convinced by Viessmann. Unjustified. Viessmann sources its ventilation systems from Renovent/Brink, and this company consistently delivers reliable products in the field of ventilation. Other manufacturers typically just put their own label on the units (to put it simply) and then sell them as their own, for example Wolf.
Both proposals for the valves are still less than ideal. It’s best to have a professional handle it—they do this daily, and usually the planning is free, as already mentioned. Not only with Zehnder.
