The warming is physically conditioned, it will not work completely without warming. Practically, the warming is not noticeable. Since the air contains less moisture, you feel the heat less.

Less efficient dehumidifiers usually generate even more heat. The heating is due to physics, but hardly noticeable. (If someone needs additional heat or the room is very cool, then the adsorption dryers Meaco DD8L or Meaco Zambezi with additional, stronger air heating are recommended).

All dehumidifiers work according to this principle. Otherwise you have to install an air conditioner (with exhaust air to the outside). These usually support a "dehumidify" option. Only dehumidifiers with "absorbent" granulate do not generate waste heat.
