Every year, Bill and I like to see how long we can go without turning the furnace on 'downstate'. This year, we have made it to November 1st...so far...and counting. I think the end is near though.
It has been below freezing on a couple of nights, but we never touched that thermostat! Good thing that we have a warm down comforter...and a little space heater named Cleo.
Up north at the cabin, it's different. Bill lit the pilot light on our old propane furnace this weekend. We have to heat our utility room because our well head is located in there. It's no longer legal to have a well head inside of your home, but ours is the original well.
We also use a heatilator as our primary heat in the cabin. The heat from a heatilator is very dry. I have to run a humidifier constantly and that doesn't keep up with the humidity. Sometimes I heat water on the stove and let it steam.
