@privateblack @joepie91 I use a #deshumidifier, no choice. A little bit electricity consumption, and does not heat really.

Cellar is under me, it's not well isolated behind me and cellar.
But I have very serious psychrometers: one, japanese, plastic, the other french old Jules Richard with ventilation and two mercury thermometers who can read half degrees o_O

The electronic #hygrometer on the dehumidifier says 59% lol
