At night when going to bed, I close the hallways doors and run a ceramic space heater in the bathroom/bedroom area. I don't have any windows in this area cracked open and I don't get any condensation.
But the living room does since it's not being heated at night. So when I get up, I'll turn on the furnace and then crack the living windows and they dry up quickly.
The small windows below the larger ones, also have condensation and I wipe those with a towel.
Good Luck and thanks for the infor- John
p.s. cold to us down here is 40 degrees
