Abstract: A stove with a continuously open draft provides a fire chamber peripherally configured to cause circular motion of burning gases therein to provide substantially complete combustion of fuel. A continuously open elongate draft vent is positioned above and immediately inwardly of a door window to aid cleaning of that structure and to reinforce the circular motion of combustion gases. Baffles and exhaust dampers also are configured to aid the circular motion of combustion gases in the fire chamber. Heated surfaces defining the upper fire chamber walls catalyze the combustion reaction and rearward surfaces reflect radiant energy back into the combusting fuel to further aid combustion.
