What can I do if I cant use a dehumidifier when it's too cold in the room for the winter but the basement really needs it?

The basement is non insulated but it's really sticky and smelly down there

    Buy a more expensive unit that has defrost cycles. The only other option is to heat the basement or put an exhaust fan in a window with fresh air coming in a window on the other side of the basement. This will help control mold.  Also, get a humidistat and keep the level below 50%. For the short term solution, place an electric space heater behind the coils of the dehumidifier to prevent freezing up while running.

    What? A dehumidifier creates a significant amount of heat when it runs. I don't understand why or what is too cold for a dehumidifier. Colder air tends to contain less moisture in it anyways, so it's not like you need one when it's 35 degrees in a room.

    Buy a hygrometer or two so you know what the humidity levels are, not just guessing. Above 60 or so readings, turn on the dehumidifier. If you need the basement closer to 50 then set it for that.

    The dehumidifier won't make the room colder.  It may make the room FEEL a bit colder because drier air feels cooler than wetter air at the same temperature.  But running the dehumidifier, because it isn't 100% efficient, will actually make the space a tiny bit warmer.

    Sounds like you may need a dehumidifier in the basement. There is no reason why you couldn’t use one during the winter or if it cold in the basement.

    you dehumidifier should work as long as the temp is over freezing down there

    You CAN use a dehumidifier in a cold room. Actually, heating the room without adding humidity decreases the relative humidity.
