Abstract: According to embodiments of the present invention, a pellet stove includes a firepot assembly with a bottom plate slideable along rails to move between a closed position during combustion in the firepot and an open position during ash removal. According to other embodiments, a firebox or combustion enclosure includes a plurality of airfoils formed on the inner and outer surfaces of the enclosure to facilitate heat exchange between exhaust gases flowing across the inner surface of the enclosure and air blown across the outer surface of the enclosure. According to some embodiments, the airfoils and enclosure are of integral unibody construction. According to yet other embodiments, a user sets parameters via a wall control unit, and a stove control unit receives the parameters and automatically controls fuel feed rate, ignition, convection blower, combustion blower, and/or firepot cleaning based on the one or more parameters.
