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!

In our basement, a Tecalor 403 Sol is operating.
Tecalor is a subsidiary of Stiebel Eltron.

Is this a combined system where the ventilation unit also provides heating (similar to what Bien-Zenker offers in their prefab homes)? Or is the heating done via underfloor heating?From what I have seen, found, and been told so far, the system starts with an air-to-water heat pump or a ground heat exchanger in the circuit. Then the air is supplied to the ventilation units, and at some point, there is a central point where a ventilation device with heat recovery is installed. The supply air to the rooms is then heated using an electric supply air reheater. The exhaust air from the rooms passes through a plate heat exchanger—let’s call it cleaned—recovering the heat once again before the remaining air is exhausted outside. That’s how I have understood it up to now.
What I wonder is, does this only work in passive houses or also in something like a KfW 55 rating?

However, the Tecalor 403 combines everything in one unit: heating, hot water, and ventilation.

As mentioned earlier, ventilation systems are now installed in virtually all commercial buildings and are regularly inspected. If they were as dirty and problematic as often described in forums, many shopping centers, office buildings, and similar places would have been shut down long ago.
Regular maintenance is the key—those who neglect maintenance actually encourage contamination.
I also believe that shutting down these systems after a certain number of years, as mentioned at the beginning, is usually a result of insufficient maintenance.
However, much of the concern also stems from a lack of knowledge and fear of progress.
