Bite the bullet and install a Co-Vac heater and set it at 50 degrees. Thats what I did and my stuff never sweats. The heating bill hasn't gone up much. It puts out radiant heat and feels like the sun when standing out in front of it. I also hate winter but will be stuck in Illinios for at least 7 more years until I retire. Then we hope to move on to a warmer climate.
