It takes X amount of btu to heat an area, if it's not going up the chimney it's going in the house.
Agreed! I've never operated a coal stove with a hopper. I don't understand how a hopper fed stove holding "X" BTU in coal is burns any longer than a batch stove with the same "X" BTU of coal in it's gullet. Coal heat output is controlled by the air fed to the combustion zone - that's the throttle. Efficiency is a matter of air feed, stove surface area and flame path. I've gotten up to 28 hrs on hi-idle with a lot of fire left to start the new load of coal in a reasonable time. Again - I'm not familiar with hopper control burn charistics. Like Coalfire stated: X in , X out or the coal isn't burning.
