I'm in NYS. One time my furnace broke, and I was a couple days without, as I found a source for parts. It was maybe 30 or so degrees out. I left a hair dryer running in the hall, and used a space heater in bedroom. When I was in the living room, run a couple burners on the stove. Even with that, I still froze.
