Most of our windows are only about 2 ft tall, just the long, short ones up near the ceiling. Our only two normal windows are in the living room. We still need to put up the plastic lining, but we have invested in the eclipse curtains (and put up blinds this summer) to help block out some of the cold.
Since we have one space heater and spend a lot of time in the living room, we decided to put up heavy curtains across our living room doorway. It has helped to keep a lot of the heat in, and on really cold nights we sleep on the pull-out couch bed as opposed to relying on each other for warmth in bed
Our electric bill hasn't been too bad - last month was $140 - but I still am thinking that we should unplug stuff when it's not in use.. I just need to work around the plug in's for the aquarium, and the Christmas tree.. Because I like it on 24/7 when I am in the living room. It might also help I suppose if my laptop didn't stay turned on and plugged in 24/7.. LOL
Thank you for this thread!
