ABSTRACT:
The present invention provides a stove having the following features: a firebox for initiating the combustion of fuel, the firebox including a lower portion with a draft inlet therein; a first conduit disposed under the firebox for conveying combustion air to a draft inlet and for insulating the underside of the firebox; a secondary combustion chamber for receiving hot gases of combustion from the firebox and continuing the combustion; a second conduit which receives air from the first conduit adjacent the draft inlet and which conveys all the air which has not passed through the draft inlet along the periphery of the firebox and into the secondary combustion chamber, thereby increasing the flow of air through the secondary combustion chamber during periods of low combustion and for continuing the insulation of the firebox; and a third conduit for conveying the gases of combustion from the secondary combustion chamber to a flue.
