decentralized ventilation - various manufacturers

Still, I have to equip every room I want to ventilate with its own device. With a controlled residential ventilation system, I can plan two supply lines and two exhaust lines for 4 rooms. With decentralized ventilation, each room needs its own device.

Or alternatively with an inverter again, then it would work again, but especially in the bedrooms that wouldn’t be so ideal. Or there seems to be some kind of intermediate solution, a decentralized device to which several rooms are centrally connected.

I just find it hard to compare costs with the devices. What does a decentralized system cost if installed in all rooms, as with a controlled residential ventilation system? Isn’t the price difference to the controlled residential ventilation system then not that big? On Idealo it starts at 300€ and goes up to about 1,000€ per device. For 7 rooms, let's say 7*500€ = 3,500€. If a controlled residential ventilation system costs 7,900€ (current offer from a general contractor to me) you “save” half.

I just have to ask myself if it’s worth it.

If a controlled residential ventilation system costs €7,900 (current offer from a general contractor to me), you "save" half.

I assume that everything is included in the €7,900, including delivery and installation. With the price for the decentralized system, you probably have to add the installation costs. Depending on the building structure, a core drilling is then required for each device. My opinion: In new buildings, central controlled residential ventilation. In existing buildings, retrofitting, modernization: decentralized, if central becomes too complex.

I'll bump up the old thread.

We'll also install 6 devices in a 95 sqm apartment.

Currently considering the Ambientika wireless devices from Südwind.

Can anyone say something about the devices?

Hello, the devices from Südwind are the same as those from e.g. Vaillant. I had the devices about 3-4 years ago and was not satisfied. The manufacturer is the Italian company Oerre.

Hello Higil, which decentralized system would you currently recommend? Still Seventilation? Greetings

I would also be interested to know which systems are currently recommended. I am somehow overwhelmed by the offerings and cannot really assess which ones are good or rather worse.

Does anyone have experience with the devices Oxxify.smart 50 or RL50RWV? They seem to be okay in terms of technical parameters. Is control via WLAN practical, or should additional switches be installed for that?
