1327.35 lbs. coal fed into the Kaa-4 in March. 781 HDD's. I estimate 3 lbs. per day for DHW and the rest for home heating.

(1327.35-93)/781= 1.580 lbs. per HDD for home heating only.

HL - 220°
LL -165°
Dump - 225°
Timer - 52 sec every 10 min
Thermostat - 72.5°
Air & Feed at 7.26 lbs/hr

1940's cape cod with decent windows (at just under 1,900 ft elevation). No insulation in brick/plaster walls, attic insulated with 12" fiberglass
