Husa, M V

An apparatus for improving the heating characteristics of a fireplace for an enclosed area is disclosed. A heat exchange conduit extends concentrically through the chimney for a distance and then connects at one end to a ducting system having at least one outlet within the enclosed area. The other end of the conduit is connected with a plurality of bent arms which are positioned in the firebox and they, in turn, connect with a manifold pipe. The manifold pipe is a horizontal member having heat sensitive valves in the ends thereof, and orifices along the length thereof directed toward the firebox. A fan is positioned within the ducting to pull air primarily from the enclosed area and force it through the conduit.
