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!

How is this done with internal insulation?
We have a timber-framed house that needs to be insulated on the inside. I can’t answer that, as I don’t have the necessary expertise. I would recommend discussing it first with a certified expert and an energy consultant, and then having an architect prepare the implementation plans.
Best regards, Bauexperte

We have a timber-framed house that is going to be insulated from the inside.Whether it’s internal or external insulation doesn’t really matter at that point. I drill a core hole, insert the tube, and pull my cables to the ventilator through it.
The advantage I see with internal insulation is that you can easily run the cables underneath the insulation.

can anyone share information about Zehnder ventilation systems?!Hello Payday,
This is a bit older, but maybe it will still be useful for someone. Unfortunately, I cannot provide any information about Zehnder ventilation systems.
However, I have had very positive experience with a decentralized residential ventilation system from getAir (SmartFan). We have been using it for about 3 months now and I am absolutely impressed. If you have any questions, feel free to contact me.

Is that why you signed up? We have been living in our house with a Zehnder ventilation system for 1.5 years already.
