Heating device

A heating device adapted to burn a combustionable fuel in a room, which comprises:

• an outer shell having a top, a bottom, and depending sides therebetween;
• an inner shell having a top and depending sides, said inner shell adapted to be installed within said outer shell in spaced relation to provide an exhaust chamber therebetween extending across the top and at least partially down a side between said inner and outer shells;
• an access aperture through a side of the heating device of a size sufficient to allow placement of a combustionable fuel within said inner shell;
• a grate with a plurality of apertures therethrough adapted to substantially extend in spaced relation above the bottom of said outer shell to receive said fuel thereon, forming a combustion chamber between said grate and said inner shell, a portion of the top of said combustion chamber adapted to be in fluid communication with said exhaust chamber;
• an exhaust port adapted to exhaust combustion gasses from the exhaust chamber through the exhaust port beyond the heating device into a suitable fluid duct to atmosphere;
• a baffle in said exhaust chamber between the inner and outer shells, said baffle adapted to extend partially down a side in spaced relation between said inner and outer shells;
• a damper positioned within the exhaust chamber and adapted to be adjustably positioned to provide through passage of combustion gasses from the combustion chamber through the exhaust chamber to the exhaust port;
• said damper adapted to be adjustably positioned to substantially divert combustion gasses in the exhaust chamber downwardly along said baffle within the exhaust chamber to extend the distance travelled by the combustion gasses prior to exiting from the exhaust chamber through the exhaust port.
