We have had a dehumidifier in the basement here for years (gips im Baumarkt > 100€),
the first one worked for 20 years.
The devices usually have a hygrostat switch integrated. We set it to 65%.
Only when the relative humidity rises above that does the device start and then consumes about 80W.
In summer, the collection container is sometimes half full after just one day.
In winter it never runs, only when it is humid and warm outside and
the air in the basement cools down, the relative humidity rises.
But typical misunderstandings about gips:
50% relative humidity is not "half-wet"!
If you dehumidify to <30%, construction wood already becomes cracked.
60% is okay for comfort!
Systems with compressors (work like refrigerators) make sense. There are also ones with the Peltier principle.
These are cheaper, but their efficiency is too poor (electricity costs!).
