Got the final read on December's electrical usage...
522 KwHr. Not bad at all!
Of course, I was gone for a week of that over Christmas, during which time I shut off the water heater, so that was a pretty significant reduction. Also no lights, dishwasher, dryer, stove, or computer.
I'm sure that the heat pump came on a bit while I was gone because the temperature when I got home was 60 deg., which is where I have the thermostat set. Don't care much about that, though.
