A wood burning stove is formed with double front and rear side walls of heat conductive metal interconnected by heat conductive spacer fins and providing air passageways by which room air is heated by conduction from the walls which are heated by the burning of wood deposited on a firebox grate made up of spaced bricks supported by metal holders secured in heat conducting relation to said inner side walls. The rear side air passageway is divided into central and outer vertical sections the central one of which is closed at the bottom end and communicates with the atmosphere through an opening in the outer wall intermediate its vertical ends and with the stove interior above the firebox and below the grate through openings in the inner wall intermediate its vertical ends and adjacent its bottom end, respectively. A vertical baffle between these inner and outer walls separates said intermediate openings from each other, and a thermostatically controlled damper associated with the opening in the outer wall controls the amount of room air delivered either under the firebox grate or above it. The front side air passageway is divided into upper and lower sections separated by a viewing box closed at its outer end by a glass window and removably closed at its inner end by a pair of hinged doors.
