2202.59 lbs. coal fed into the Kaa-4 in January. 1292 HDD's. I estimate 3 lbs. per day for DHW and the rest for home heating.
(2202.59-93)/1292 = 1.63 lbs. per HDD for home heating only.
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.

Thanks Larry... It's not sipping coal like yours and Don's, but it kept the house right at 71 during the latest cold spell. we had 65.3 HDD's yesterday... A little insulation in the walls would really help but I'm not sure it's feasible.
