I had available thanks to a leaky pipe water in the basement and had the rooms quickly get dry. In addition, the basement in the summer was always moist. Both problems eliminated the device with flying colors. The wet basement was drained in three days, and on the day I was able to empty the water tank full 3x. The 25l indicated are just determined under optimum conditions, in the cool cellar things look different.
In the summer, I let the WDH run at low speed, then he turns every few hours time, and I can keep my desired humidity level without consuming too much energy. However, I need to an external hygrometer data sheets, because the device does not have an indication of the moisture determined.
So:
+ Good workmanship
+ Stable, nothing rattles
+ Excellent drying performance
+ Continuous operation with acceptable power consumption
- You can hear it clearly
- No display of current moisture
The minuses are not decisive for me, so I prefer not from Stern and give the full. 5
