A stove for burning solid fuel such as wood, coal or briquets in a more efficient manner utilizes preheated outside air for primary and secondary combustion and has tempered glass windows for observation. The combustion air flow is directed so as to minimize obscuring of the glass by deposits of unburned volatiles. A fire chamber is provided with self-feeding grate, and the stove also has a secondary grate, a high proportion of radiating and convective surfaces, a heat exchanger, a cooking surface, an automatic linkage between a fuel loading door and an opening-reducing damper to limit back drafts and thermostatic control to ensure complete combustion and efficient heat exchange. The self-feeding grate has a thermostatic grate shaker to promote unattended complete combustion, and can be replaced to match the fuel used.

In a stove comprising a housing defining a combustion chamber, said housing being provided with a window through which said combustion chamber is visible from the exterior of said stove, means defining an inlet for admitting an inflow of air into said combustion chamber, means for supporting fuel for combustion in said combustion chamber and means for directing a portion of said air inflow upwardly past a surface of said window facing inwardly of said combustion chamber, the improvement comprising means for deflecting said air inflow portion from said inlet opening under and in contact with said fuel support means for preheating said air inflow portion prior to arrival thereof at said window surface. A stove, comprising: means defining a combustion chamber; grate means in said combustion chamber for supporting fuel to be combusted; said combustion chamber defining means comprising a vertical window in the front of said stove through which the combustion chamber is visible from the exterior of said stove; a horizontal inlet opening located under said grate means at the bottom of said combustion chamber for the inflow of air into said combustion chamber through said grate means; a horizontal outlet opening at the top of said combustion chamber for the outflow of gases from said combustion chamber; said inlet and outlet openings, said grate means, said combustion chamber and said window being elongate in the direction of the width of said stove; an air inlet communicating with said inlet opening for supplying the air thereto; means for controlling air flow through said inlet; and means in said combustion chamber for deflecting portion of the air upwardly past the face of said window directed inwardly of said combustion chamber.
