Hello everyone,
we are currently planning our solid-built house without insulation. However, we are unsure whether to install a central ventilation system. The general opinion, for example in forums, is that such a system should definitely be included in a new build. Reasons given are comfort, continuous air circulation, and so on—well known points. It is also understood that it may not be energy-efficient.
BUT: I have already spoken to one or two architects who say: definitely build without it. Their reason is that everything works fine initially, but after 5 to 6 years hygienic problems can occur despite maintenance. Based on their experience, most installed systems are eventually turned off and no longer used. Some doctors also confirm this and would not install such systems themselves. Their argument is: for prefabricated houses, yes, because necessary. For solid-built houses without insulation, no.
I am torn. On one hand, I want to stay up to date with what makes sense; on the other hand, I don’t want to install something that will be switched off after a few years anyway.
I am completely unsure now whether to choose it or not and hope to get some opinions from you!
Thank you very much in advance!

I have the following idea. Please let me know if it makes sense or if it is just a bad idea. An explanation would be great.
We somehow can’t really warm up to the idea of a central ventilation system. However, the advantage/comfort we would like to have is ventilation in the bathroom to handle moisture and in the bedroom for pollen and fresh air at night, especially in winter when it’s too cold to keep a window tilted open. Manual ventilation in the other rooms would not be a problem.
Would it therefore be possible to simply install decentralized ventilation units in the bedroom and bathroom, possibly with heat recovery? Does this make sense, or would we be the first to do something like this in a new build?
Thank you very much!

Even though I do not fully agree with my partner’s view on central ventilation systems, I do see a clear advantage for our clients in being able to operate a decentralized system as they wish. For example, they can increase ventilation in one room or switch it off entirely without the entire system malfunctioning. Incidentally, in all aspects of life, I am against integrated systems: whether it is a washer-dryer combo or, as is often encountered, an air-to-water heat pump combined with a ventilation system in one device. If one part is out of order, the other stops working too...
We must also not forget the significant price differences between central and decentralized systems. By the way, this also applies when replacing components: if something breaks in a decentralized system, the bills can be surprisingly high. However, unlike with central systems, if something fails in a decentralized setup, the other fans continue to operate, and repair or replacement costs remain relatively manageable.
Ultimately, everyone has to decide for themselves whether a central or decentralized system is more suitable. THAT is a never-ending debate
Best regards, Bauexperte

However, we recommend heat recovery only in rooms where it actually makes sense, such as wet rooms and the kitchen. Of course, it also depends on the manufacturer used; we have had very good experience for years with a Berlin-based manufacturer – their customer service even comes out at Christmas and during heavy snow. For central systems, we cooperate with a dedicated division for private customers from a well-known supplier; here, too, I have not received any negative feedback or complaints about poor customer service.
thanks for your opinion. What do you think about decentralized systems then? You don’t have the "long ducts" with those.
