Hello everyone!
I have been reading and researching online and in this forum for a long time now, but unfortunately, I’m still not much wiser when it comes to mechanical ventilation with heat recovery.
My partner and I are planning a single-family house (160 m² (1,722 ft²)) with gas and solar energy, built to the KfW-70 standard. Now we are wondering whether we should install a ventilation system.
Friends of ours have a decentralized ventilation system in their new build and are very happy with it—they can’t imagine living without it anymore.
However, in various forums, people often say that for new builds, a centralized system is better. The whole ducting, with maintenance and the potential for germs, gives me a weird feeling... I would constantly wonder what’s actually in the air inside my home. Is that a misguided concern?
And is the decentralized ventilation really that much worse than the centralized system? You hear that a lot.
What kind of costs should we roughly expect for a ventilation system? Is it true that centralized and decentralized systems cost about the same?
Thank you very much for all your advice!

hi
Is that what you signed up for? We have been living in our house with a Zehnder ventilation system for 1.5 years (18 months). And are you satisfied with the system?
