Hello everyone,
We are going to build a single-family house to KfW55 standard. It will have a basement, ground floor, and upper floor. The living area is approximately 170m² (1830 sq ft) and the usable area 108m² (1163 sq ft) including stairs and basement – that’s the basic information.
Now we are wondering which ventilation system to choose, since new builds are very airtight due to the windows and insulation.
We were recommended a decentralized system, as it would be fully sufficient and requires less frequent maintenance and cleaning. Additionally, cleaning is easier and less problematic compared to a central ventilation system.
Could you share your views or experiences on which ventilation system would be most suitable?
Thank you very much.

The main difference: the Paul system included 5 exhaust and supply air ducts from the company (1x basement, 2x ground floor, 2x top floor), while Zehnder provided a complete ventilation plan with 12 exhaust and supply air ducts.
Of course, that makes a big difference in price.

That, of course, makes a big difference in price. For us, both (Heinemann/Vallox or Zehnder) had 15 ducts with a total of 11 outlets or inlets...
And both were priced gross below 10,000 euros (about 9 months ago) tendered through an architect.
Reading around here, some general contractors are already charging truly exorbitant prices.. Phew

The problem with two apartments is supposedly that, in theory, you can hear conversations from the other apartment through the duct system.
A no-go.If poorly planned...
It’s shocking to see the prices mentioned here (low); such prices are definitely not achievable in southern Germany. If "newcomers" read this, they could get the wrong impression.
The harsh reality usually hits much later, either when placing the order or, in the worst case, on the construction site in the form of additional costs.
Unfortunately, what is claimed in this thread is not credible when stating that a central system from a market leader like, for example, Zehnder, could still be installed today for under 10,000 euros for a single-family house with a basement (without any self-performed work!).
And I am not talking about general contractor prices but, of course, directly from the craftsmen. My friend recently paid around 15,000 euros and obtained several quotes. However, his house is also over 200 m² (2,150 sq ft) in size.

Bookstar,
very strange.
If it was installed today, then that is in the past and actually happened, not a bait offer.
So if the unit costs 3,000 euros and then the pipes and labor are added.
If you can end up at 10,000 euros (about 11,000 USD), that is not unrealistic to me.
