Which central ventilation system?

Hello,

we want to build a central ventilation system (controlled supply and exhaust ventilation with heat recovery) and are now interested in various manufacturers. The market is so confusing that I am interested in your experience with manufacturers.

I would find control via app interesting. It is not a must, but it would be nice. Ultimately, however, function, ease of cleaning, reliability, and power consumption should be the focus.

And do you have any tips on what we should definitely pay attention to in the execution?

Helios - not an app, but a web interface. Easy to clean, you can cheaply carve the filter yourself, power consumption is practically the same for all.

And they have good support. In our case (just bad luck) the circuit board was defective after about a year, it was quickly and easily replaced by a technician.

I have now also read many bad experiences about Helios. I just like the web interface. I mean, it's a gimmick... but a nice one

What did you pay and did you do things yourself? Because apart from changing the filter, we actually don't plan to...

Actually, it doesn't really matter what you buy and have installed, the devices are 90% identical...

What is important is that the installer knows the system and knows how to best install everything in the house.

So far, I have also read many bad experiences about Helios. I just like the web interface. I mean, it’s a gimmick... but a nice one

What did you pay and did you do things yourself? Because, apart from changing the filter, we actually don’t plan to..

We didn’t do anything ourselves. The system cost around €10,000 for about 300 sqm of floor area. Installed by our heating engineer.
