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!

Maybe there are also differences between basic ventilation systems and systems with heat recovery.

keinen nennenswerten...Unless you want to apply for funding. Depending on the federal state, only centralized systems with heat recovery are eligible for subsidies.
Häuslebau3r17 Feb 2015 07:45From what I have read in other threads, the central ventilation system is apparently only available with heat recovery, while the decentralized system can come with or without it depending on preferences. Is that correct? When receiving funding from KfW, for example for an FKW 55 house, you basically cannot avoid choosing the central system with heat recovery, based on what I have found out so far.
