Oil-filled elect heater in the bedroom at night set on low with thermo at 63 (doesn't come on much). High-eff gas furnace comes on most mornings for a quick warm-up. I turn it off, start a fire & go to work. House is toasty by the time the time the wife & babe get up. Gas for hot water & cooking too. Still, gas & electric combined is much less than half of the cellular bill About time to start burning some better wood. So far have only burned Basswood & Silver Maple. Elm is on deck. 2+ year Red Oak & Mulberry are in the bull-pen.
