I'm in Maine, too, in the Bangor area. We keep the thermostat set at about 57*F in the winter. Yup, that's brisk! My 115 year old house has lousy insulation, so after a certain temp we can turn the thermostat up and up and it makes no difference; it doesn't get any warmer in here, and we burn through oil. DH used to joke that if the thermostat is set about 60, we're just heating the front yard! This winter is better as we finally finished replacing the windows, and we'd already put down additional insulation in the attic. We have a space heater we use in the family room when it's really cold in the evening, but mostly we just each have our own throw blanket. DD's room has a space heater; she'd turn it on about 45 minutes before going to bed, but shut it off once she was tucked in. THere's an electric blanket on my side of the bed, but I don't really use it. I'll turn it on for about 15 minutes when I'm getting ready for bed and first snuggled down, but then I shut it off. Plenty of blankets are available, and we are comfortable- can't decide if I'm a hardy New Englander or just frugal (aka, cheap)!
