1853.28 lbs. coal fed into the Kaa-4 in January. 1070 HDD's. I estimate 3 lbs. per day for DHW and the rest for home heating.

(1853.28-93)/1070= 1.645 lbs. per HDD for home heating only.

HL - 220°
LL -165°
Dump - 225°
Timer - 52 sec every 10 min
Thermostat - 72.5°

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
