A woodburning stove adapted to be inserted into a fireplace having inner walls operatively forming a fire chamber and outer walls spaced from the inner walls to form air heating chambers through which air to be heated is forced by a fan disposed beneath the fire chamber adjacent to the front face of the stove. The inner walls are arranged to channel air beneath, behind, on top of and to the sides of the fire chamber in successive order before discharge out the front of the stove. A special fire chamber and flue means cause the hot exhaust gases of the fire chamber to flow along the rear and top walls of the fire chamber and through a damper in the front of the stove and into a flue chamber before flowing into the fireplace flue. The temperature of a heating surface disposed on top of the flue chamber above the damper is controlled by damper control means at the front wall of the stove.

A stove for insertion as a unit into an existing fireplace, said stove having a fan positioned in an air space therein for forcing air in heat exchange relationship with said stove and wherein said fan is located in said air space to prevent fan burn-out, said stove comprising: a fire chamber adapted for combusting fuel, said chamber having a pair of sidewalls, top and bottom walls, an end wall and a door opposite said end wall, said door being in a frontal portion of said stove and said walls forming heat exchange surfaces, said bottom wall of said fire chamber sloping downwardly from the frontal portion of said stove to said end wall; a frame positioned about said fire chamber and being spaced from said side, end, top and bottom walls of said fire chamber, said frame and fire chamber defining an air space therebetween; an air inlet formed in said frame at the frontal portion of said stove for passing air from the exterior of said stove to said air space; a fan disposed in said air space in front of and below said fire chamber for forcing air through said air space in a heat exchange path along the bottom, end and top walls of said fire chamber, said air being thereby heated, said fan being positioned in a relatively cool portion of said air space and wherein convection air flow in said air space causes cool air from said inlet to flow about said fan, along said end wall and over said top wall to thereby prevent fan burn-out due to heat from said fire chamber; and an air outlet positioned in a frontal portion of said stove for passing said heated air from said air space to the exterior of said stove.
