High efficiency wood pellet stove

A wood pellet stove for efficiently burning wood pellets, the stove comprising:

• a stove housing having a top, a bottom, a first side panel, a second side panel, a front portion with a fire box access door for providing access into the front portion of said housing and a rear portion;
• a fire box with fire box floor disposed in the front portion of said housing, said fire box having fire box walls angled outwardly toward opposite sides of said fire box access door;
• an annular shaped burn pot disposed on said fire box floor and centered thereon, said burn pot having a burn grate and pit for burning wood pellets therein, said pit sufficient in size for holding enough pellets to provide maximum heat output of the stove yet small enough to maintain a low burn efficiency, said burn grate received on top of said burn pot;
• a wood pellet hopper disposed in the rear portion of said housing for holding wood pellets therein and having means for feeding wood pellets into said burn pot;
• and
• a hollow low burn core extending upwardly from a center of said pit, the burn core have spaced apart holes therein for providing combustion air to the center of said pit and thereby providing more efficient burning of the wood pellets at low levels.

• a control panel mounted on said housing and having a microprocessor;
• an air and exhaust gas fan mounted in the rear portion of said housing, said microprocessor electrically connected to said combustion air and exhaust gas fan for regulating the amount of combustion air circulated through said housing;
• an air flow sensor mounted in an air inlet tube received in said housing for sensing the amount of combustion air introduced into said housing, said microprocessor electrically connected to said air flow sensor for monitoring the amount of combustion air received through said air inlet tube;
• and
• a exhaust gas temperature sensing means connected to said convection air fan and connected to said microprocessor for sensing exhaust gas temperature exiting said housing and controlling the operation of said convection air fan.
