...I've been monitoring my coal usage pretty religiously and have it down to about 12# per day or a half pound per hour.
I am averaging 13 1/2 pounds per day for hot water and "pilot fire" I do not know if it can be cut back any more than that or not. I am burning buckwheat coal, I could also burn rice or a mixture of both. I don't know if using rice or a mixture would affect coal usage or not.

My sides are insulated, the top is not. I may try adding insulation on the top. Right now boiler temps are at 150 most of the time, aquastat set for 140, basement temps not too warm either but adding some insulation to the top of the boiler can't hurt.
