Kaa-4 - January Tale of the tape

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.

I have very similar numbers for my KA-6, about 2,500# for January heating an old drafty uninsulated farmhouse.

Similar results here.
KA4 on Lehigh rice
(1760-93)/1071=1.55#/HDD.

1960s ranch. 3,000sf heated to 68-72*. Attic R28, walls ? Maybe r8-10.

Sounding like the Keystoker's made it through the brutal cold!
