1. A stove for converting fuel to heat, comprising:

  • a housing,a thermal partition means comprising first and second parallel, spaced-apart vertical walls defining a thermal barrier therebetween, said thermal partition means arranged within said housing and dividing said housing into a hot side for receiving and burning said fuel therein to produce heat, and a cold side insulated from said heat, said second of said walls including an outlet therein for communication between said thermal barrier and said cold side, said cold side including a fuel hopper for holding fuel,a chute extending downwardly from said fuel hopper into said hot side through said thermal barrier, said chute having a portion positioned within and communicating with said thermal barrier and extending into said hot side through said outlet,fuel feeding means mounted in said fuel hopper at an upper end of said chute, said fuel feeding means adapted to feed fuel from said fuel hopper down said chute and into said hot side for combustion,an air blower for supplying fresh air from outside of said stove into said cold side,said thermal partition means dividing all of said air supplied from outside of said stove into said cold side into two portions, a first portion and a second portion, said two portions constituting all of said air supplied from outside said stove,said thermal partition means being arranged to conduct all of said first portion of said air through said thermal partition means into said hot side for enhancing combustion in said hot side,said thermal partition means conducting said second portion of said air into said thermal barrier, said thermal barrier being arranged to force all of said second portion into said chute and through said outlet into said hot side, such that all of said second portion of said air is conducted directly from said thermal barrier into said chute and then into said hot side,whereby when said fuel is fed by said fuel feeding means into said hot side and ignited to produce heat, said thermal barrier is cooled by said second portion of fresh air supplied by said air blower, whereafter all of said second portion of said air will be conducted into said hot side, so that said second portion of said air cools said thermal barrier to prevent heat from said hot side from reaching said cold side and all of said air supplied from outside of said stove is ultimately used to enhance combustion in said hot side.
