  • Patent number: 4373506
    Abstract: The present invention relates to a stove of the type having a firebox and a second outer wall that defines an air passageway around the fire-box. Provided with the stove is a fan for forcing air around the defined air passageway for collecting heat from a burning fire within the firebox. A flue is communicatively connected with the firebox and extends therefrom through the defined air passageway and on through the outer wall structure of the stove. Co-axially disposed around the flue and communicatively connected with the air passageway is a vent for directing heated air from the stove. The co-axial relationship of the vent and flue assures that the flue gases must pass within the heated air passing in the vent or vice versa, and this gives rise to a very efficient stove inasmuch as a substantial portion of the heat associated with the flue gases being exhausted is transferred to the vented air.
