For December, I am using 23.6 kwh per day for residential electric plus
39.09 kwh per day for the electricity for the hyrdro heat (heat pump) heating system. I typically also burn one tank (500 gallons) of propane per year when the secondary heat kicks in (and stove, fireplace, generator).
I have a whole bunch of PCs / server / wallwarts / TabletPCs / Ipaq / etc plugged in 24x7.
The house is built very energy efficient and air tight which helps offset the high ceiling height (37 ft across most of the 1st floor), 38 argon filled windows 2 doorwalls and skylight, and 6500 sq ft.
Hydroheating w/ propane secondary controlled by RCS TR40 and MainLobby Elk Plugin
Foam form basement 9" walls (including all sides of theater room for sound proofing) with 2 inch foam below slab in basement and garage
Cellulose insulation in all 2x6 exteriour walls, foam filled in all 2x4 walls (around window banks).
All blocking and headers foam filled.
Windows foam sealed (mistake - doesn't allow for shrinkage which traps windows
Tyvek wrapped
100% filled ceiling joists with cellulose (12 inch thick) w/ wood tongue and groove ceiling.
Garage is on propane furnace - 2x6 walls w/ fiberglass insulation plus 2 inch thick foam under slab. foam filled overhead doors. Fiberglass insulation above garage ceiling.
If I didn't build so energy efficient for Michigan winters, I would be broke!
