Abstract
A free standing ceramic fireplace having a refractory base member including a hearth extension adapted to rest on a floor of a mobile home or other type residence. The fireplace has a refractory ceramic outer shell supported on the base and extending upwardly therefrom, and has a refractory ceramic, generally spherical, combustion chamber supported within the shell and closed thereto. There is a combustion air inlet to the combustion chamber extending from below the floor and a combustion gas outlet in the combustion chamber. A flue is fitted in the gas outlet and extends upwardly through the ceiling of the room. There are aligned openings in the shell and combustion chamber for inserting solid fuel into the combustion chamber. A room air passage extends in the shell in a space outwardly of the combustion chamber and the passage has an upper opening through the shell to the room. It extends downwardly in the shell around the combustion chamber, terminating in the shell below the last chamber where a heated air storage chamber is formed. There is a continuation of the passage adjacent the base from the heated air chamber to the room. There is a glass door for closing the opening in the shell and the opening in the combustion chamber. A thermostat actuated motor-driven fan is positioned between the heated air chamber and the passage therefrom to drive heated air into the room adjacent the base. When the fan is not operating, hot air will flow upwardly through the room air passage out of the top of the shell.
