Heater stove apparatus

Claim 1

Heating stove apparatus comprising: an enclosed stove housing; a fire chamber within said housing in which a suitable fuel is burned for heating; a draft door carried by said housing providing access to the interior of said fire chamber; a heat collector manifold receiving the heat and combustion products from said fire chamber; a plurality of elongated heat delivery pipes extending between said fire chamber and said heat manifold for delivery of heat and combustion products thereto, said heat pipes having open opposing ends communicating with the respective interiors of said fire chamber and heat manifold; horizontal air flow path means extending generally vertically the height of said elongated heat pipes and extending generally horizontally along one of the dimensions of said stove housing, said air path means being defined in part by a bottom surface of said heat manifold and an upper surface of said fire chamber; said heat pipes being arranged and aligned linearly in rows across said air path means with the heat pipes of next adjacent rows being offset in their relative lateral spacing; said heat pipes of next adjacent rows being spaced approximately mid-ways between the lateral spacing of heat pipes in said next adjacent row whereby said heat pipes contact said air flow head on and present an enlarged heat transfer surface transverse to the flow of horizontal air while affording sufficient space between said pipes to facilitate said air flow; circulation means providing circulation of air generally horizontally through said stove housing along said air flow path means; and a water reservoir adjacent said fire chamber carried within said stove housing being open at the top for release of water vapor into said air path means.
