Since there are already so many reviews, I keep my short as possible:
Positives:
- The unit is relatively quiet (by the closed cellar door grad still audible (when active at that moment))
- Works well (my cellar holds really dry; dries to about 20 m2 large basement room in less than 1 hour from 65% to 60% down)
- Desired humidity limit set (in steps of 5% - it will always be when it reaches the limit by 5% "herunterentfeuchtet")
- Fully automatic
- The roles are also very practical
- Display for tank level available
- Runs with me since now about 2 years in the permanent automatic mode without any problems / defects
Negatives:
- The machine clatters sometimes (but by vigorous shaking on the unit until the next time this is remediable)
- The tank is regularly fully after 2-3 days in my basement in summer. This I have to empty the tank frequently. That would not be so often when the tank would have a higher capacity (eg 10L). This I feel in my application to be very strong disadvantage, which is unnecessary. On vacation the example is a real problem. Therefore, / I will not give more than 3 stars in person. The tank holds effective only about 2L of water before is automatically switched off. The tank thus occupies much less than 1/5 of the total volume of the device. So there would a lot more without the device to make a total of too big.
My brother has but a dehumidifier with approximately the same external dimensions, the tank holds 5 liters of water - after all, but 10l would be better - or at least one hose connection on the tank, so you might direct the water down the sink or in a large container (some competitors offer this).
Power consumption:
In my application (an approximately 20m2 large basement room), the device consumes an average of about 200 kWh / year. So that makes at 0.25 / kWh -> 50 Power Consumption / year.
Conclusion:
Dear producers, this is overall a really successful device but please, please do the next model the tank significantly larger - at least 10 liters - or offer a way to attach a drain hose. Thanks!
