We just passed our first year using the Fujitsu 12RLS for heating, with the exception of a 7-1/2 day period in early February when I switched back to the oil boiler to get some data, which was equal to about 5% of the HDD65s in this one year period. The heat pump energy consumption at the meter was 1,366 kWh - adding the missing 5% brings the consumption up to about 1,441 kWh/year. I don't know if that is the full number, as we have learned that the electromechanical meters don't always pick up the low wattage periods of consumption. The HP was off at the breaker for close to 6 months, May - October.
This works out to about 0.28 kWh/HDD65. We keep the first floor bedroom and bath closed off and they only are heated by conduction through the walls. The remaining gsf of the house is about 1,300. So heating is about 0.73 BTU/sf/HDD65 in terms of input energy. If the Fujitsu is operating at an overall COP of 3, then heating demand is about 2.2 BTU/sf/HDD65, which is believable - a little lower than I'd expect, but we don't keep it at 70F unless we're there and awake (70F under those conditions, 66F otherwise).
I've got Hobos set-up now logging temps on the main floor where the HP is, the bedroom upstairs, the basement, and outdoors, so I'll have a better idea of performance as we move through the winter. Overall, we're very pleased with this gizmo. I think we've paid about 1/4 the cost of what we would have if we'd used the oil boiler instead!
