This year total usage here at the house is 3,808 kWh. Of that, 1,037 kWh went into the Fujitsu heat pump; 861 kWh went to the refrigerator and chest freezer; 598 kWh were used for water heating in the heat pump water heater; 176 kWh used in the range, and 164 kWh by the well pump (dry summer, lots of drip irrigation); lights and plug loads totaled 315 kWh. November and December were just a bit colder than the 5 year average, after a very warm winter last year.
The PV system generated 6,309 kWh, for a net export of 2,501 kWh. We really should be driving an electric car!
This winter I'm re-doing experiments I did last winter, with (I hope) better set-ups. I'm measuring the effectiveness of the Zehnder ComfoAir 200 ERV at recovering heat from the exhaust air and putting it into the supply air. And I'm logging pressure difference between the basement and outdoors, as well as outdoor temperature, and attempting to find correlation with radon levels.
