ᐅ Manufacturers / Brands for Central Ventilation Systems? Selection Criteria?

Hello everyone,

I am currently planning my detached single-family house with a manufacturer of solid prefabricated houses.
Which suppliers/brands are available for central ventilation systems? What criteria should I use to choose one?

Do you have full freedom of choice with the prefab house supplier? They probably have their own preferred options.

Yes, he definitely has a supplier. I haven’t asked about the central ventilation system yet. Maybe it’s possible to negotiate a different model if the current one is too cheap or of poor quality and noisy. Otherwise, you might end up regretting ventilation noise for 15-20 years...

Basically, most of them are quite similar.

But among them are: Hellios, Vallox, Wolf, Brink, Renovent, Pluggit, Vaillant, Zehnder, Systemair, and so on.

Do you actually read the forum section where you post, or do you just ask questions without thinking? This question is similar to "which car is the best?"

Maybe that’s because we are relatively new to the forum and haven’t posted in the four-digit range yet?

Does that mean they are also similar in terms of quality and price? Who tests these systems regarding their quality? There isn’t really anything like Consumer Reports or similar, is there...?
