Hello everyone,
We are currently planning the construction of our single-family home and are considering whether to install a decentralized or centralized ventilation system. According to a preliminary quote from a general contractor, there is a cost difference of about 8,500 euros (cost for decentralized) versus about 13,000 euros (cost for centralized), which I had expected to be higher. We are currently living in an apartment with a decentralized ventilation system and are dissatisfied with it. Mainly, we are bothered by the noise of the fans themselves and the external noises that come through because of that.
Therefore, I wanted to ask you which option you chose. Are you satisfied with it? Would you choose the same again?

A central controlled residential ventilation system does not have individual room control, at least not for the price usually charged in single-family homes.That is incorrect. Airflow can and is indeed adjusted in the distribution system. What you are referring to relates to secondary adjustment via actuators. Please be a bit more precise when "ranting."
The ventilation ducts can definitely be cleaned with some effort if(!) it becomes necessary!
And if I have mold in the room: Yes, where does it go? Into the exhaust air, through the heat exchanger, and out.
I’ll take the liberty of quoting myself.
Or to justify their own wrong decisions afterwards. 😉

With a decentralized ventilation system, I can control each room individually if I want, or at least separate the upper floor and ground floor.Be honest, how many controllers do you have? One per floor or one per room? xMisterDx schrieb:
And I simply replace a broken fan. It costs 500 EUR including the heat exchanger. How much does the central fan of the controlled residential ventilation system cost? 😉Keep in mind that every single fan can break down eventually (we’re talking decades here). 6-8 times 500€ doesn’t seem that much cheaper anymore.One of my Lunos e2 units has now failed after 9 years. It’s making a rattling noise. I removed it and stuffed some Styrofoam into the hole. It’s just in the office, which I only ventilate occasionally by opening the window when I work in there anyway.
A central ventilation system should be cleaned regularly because mold in the ducts is no joke. Decentralized systems are easier to clean.

I have never seen it done exactly like that, but let’s ask Rottenmotor what they think?
Probably no concerns? 😀
