Hello,
I don’t believe such a system is absolutely necessary, or rather, I haven’t yet seen the significant benefits it offers. I prefer to simply open the window. What are the advantages of a ventilation and exhaust system, and what might be the drawbacks?

Installation only or including the device and piping?

That’s roughly correct. With installation and all appliances included, our general contractor charged just under 12,000.

The 10,000 euro mentioned to me included the unit and piping.

As Baumhaus has already confirmed, yes, 10K is absolutely common.

Exactly. For us, the ventilation system costs a total of €10,500 including the equipment, installation, and ductwork.

Since today, I’m supposed to ventilate the house by fully opening the windows three times a day to help the screed dry.

It took me 6 minutes to walk through the entire house once and open every window.

6 minutes opening, 6 minutes closing, twice a day, equals 24 minutes per day.
168 minutes per week, 730 minutes per month.

12 hours and 10 minutes per month spent on ventilating.

I’m really looking forward to our ventilation system.

The costs are 13,500€ (euros). Assuming a lifespan of 20 years for the system:

Time saved per year: 730 minutes/month × 12 months = 146 hours
Time saved over 20 years: 2,920 hours

Cost per hour of saved time: 13,500€/2,920h = 4.62€/hour

You can interpret such a calculation however you want – without the ventilation system, I probably wouldn’t have to open EVERY window – but it still makes you (at least me) realize how much time you spend on things that could be handled automatically.
I’ve made worse deals than paying 4.62€ for an hour of free time.

I wasn’t even aware that so much time goes into ventilating.
