  • Patent number: 4217094
    Abstract: A combination safety and heat conservation panel is disclosed for use with coal or wood heaters or the like. Where the stove flue passes through a wall, the panel is placed between the wall and stove. The panel is hollow, permitting heat radiating from the stove to pass through the panel wall to the panel interior. From the panel interior, the hot air is directed by appropriate means, including fans, baffle and fins, out an end of the panel where it may more freely circulate within the room itself, or whereby, with appropriate connecting pipes, the heat may be directed to other rooms of the house.By thus absorbing and transferring heat which would otherwise tend to collect in hot spots between the heater and the wall, enhanced safety against fire and heat damage is provided. A further benefit derives from providing better circulation of heat in the room by removing the heat from the unneeded area proximate the heater and the wall and transferring it or allowing it to flow naturally to other parts of the room.
