Abstract

A woodburning stove having an inner housing and an outer housing spaced therefrom providing air passages therebetween. A blower circulates air through the air passages for absorbing heat from the walls of the housing and exhausting the heated air into the room where the stove is located. A substantially horizontal plate is spaced below the top wall of the inner housing defining an afterburner space. A duct extends between the passages extending between the two housings and the afterburner space. The duct is provided with a valve so that fresh air can be controllably applied to the afterburner space for causing combustion of gasses flowing through the afterburner space. A fresh air duct extends along the side of the stove and connects with the blower for supplying fresh air from the front of the stove to the blower.
