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!

Which zigzag profile? My pipes are completely smooth on the inside, even if they appear "ribbed" on the outside. There is an additional inner layer. So apparently there are hygienic and non-hygienic systems, but you could say the same about refrigerators, yet everyone has one. So-called composite pipes have long been standard technology, regardless of well-known manufacturers like Fränkische, Hegler, Pipelife, Wavin, etc. Smooth inside/wavy outside pipes have long been used both in ventilation systems and in wastewater/rainwater, drainage pipes, and cable protection conduits...
A pipe ribbed or corrugated on both the inside and outside is like a single-layer standard drain pipe, for example according to DIN 1187 or DIN 4095... Is this profile still used by manufacturers in ventilation systems?

Holzwurm220 Dec 2014 16:03Hello Siko82, we have been living in a house with an air-to-air heat pump (Proxon – Weberhaus, sold by Proxon (Zimmermann ventilation)) for 6 months and have had only positive experiences so far.
Acquaintances have had the same system for about 10 years with no issues regarding "hygiene" or similar concerns. Of course, regular filter changes are important (if you look inside, you can see everything that’s in the air). Regarding running costs, I can only provide current electricity consumption measurements. From October to December, it is about 400–500 kWh per month; in summer, approximately 100 kWh per month. Overall, this adds up to an estimated 4000 kWh per year — which is a good value for a 160 m² (1720 sq ft) house (we have a KfW 55 standard home, energy certificate about 42 kWh/m² per year).
From my own experience, architects tend to be very inflexible and often hesitate to adopt new technologies.
Recommendation: install an air-to-air heat pump and save!

Holzwurm, could it be that you are referring to your heating system?
This discussion is about ventilation systems.In this case, it’s actually the same thing...
