In attic grows, it's practically indispensable. It keeps the temperatures in check even in summer and simultaneously supports dehumidification. I deducted points only for power consumption and noise, which are hardly avoidable due to the design.
This time I did not use the named DeLonghi dehumidifier but an ALDI Nord Quigg 20/d dehumidifier. And I did not use it a lot. Just at times, when had more than over 80% humidity.
