Abstract: A fireplace stove comprising a generally rectangular metallic housing adapted to extend into a fireplace opening, with penetration being limited by a flange around the housing which engages and seals against the face of the fireplace. A metallic inner fire shell is closely spaced within the inner surfaces of the housing to provide airflow passages between them. An air inlet with a blower is located at the lower end of one side of the housing and a narrow, hot air outlet extends across the top. Air is directed to flow almost completely around the fire shell for maximum heating. An air inlet with a blower is located at the lower end of one side of the housing and a narrow, hot air outlet extends across the top. Air is directed to flow almost completely around the fire shell for maximum heating. An access door is held in sealed engagement by a spring latch and a combustion air duct in the door extends into the interior so that the air entering thereto is preheated before actual contact with the fire.
