ᐅ Basement ventilation system without windows

Hello everyone,

Our ventilation system has finally been up and running since the weekend.

The air quality in all rooms is noticeably much better than before. So far, I’m really impressed!

Our ventilation installer mentioned that it’s possible to program the current setting from “1” to “2” during the day and then have it automatically switch back to setting “1” at night to keep the noise level low.

At the moment, I don’t find the air quality bad and don’t see a reason to increase the setting (but this shouldn’t cause any disadvantages, just stronger ventilation, right?). In my opinion, setting “2” is hardly audible either!

Do you usually ventilate bathrooms manually with windows after showering when you have a ventilation system, or can/should I generally avoid manual ventilation?

Our basement currently has a constant humidity level of 70%. We have no windows there since it’s purely a utility basement. The ventilation system is connected in this area as well.

A few weeks ago, we had serious mold problems because we stored a lot in the basement and the ventilation system wasn’t running yet.

Now my question:

Do I no longer need to worry about mold as long as the system is operating? Can mold develop even with continuous ventilation? I probably won’t be able to lower the 70% humidity quickly since we have a waterproof (WU) basement and it’s a new build that needs time to properly dry out.

Is drying laundry an issue at this stage? We have a separate laundry room in the basement that is also ventilated by the system.

Or:

Should I generally wait a few more months before using the basement as a storage space?

I look forward to your feedback 🙂

Common manufacturers don’t differ much in this respect. They all measure the necessary parameters at a central point and automatically regulate themselves in the corresponding operating mode, for example to ensure moisture protection. However, measurements are only taken centrally, which means that potentially too humid air from the basement is mixed with the exhaust air from other parts of the building.
