ABSTRACT:
A combined fireplace hood and heating unit which is adapted to be mounted as an assembled unit to the lintel of a pre-existing fireplace. The unit includes a fireplace hood formed as an elongated housing, and a pair of U-shaped heat exchanging ducts each having a rectangular cross section and each extending in cantilever fashion from the rear of the housing. Brackets are provided at the front-to-back center of gravity of the unit for suspending the unit from a fireplace lintel such that the housing is carried externally of the fireplace and the heat exchanging ducts extend rearwardly into the fireplace over the fire or hearth area. The housing itself is the only connecting duct between the blowers and the intake vent, so that cool air entering through the intake vent tends to circulate throughout the housing and cool all components therein before being forced through the heat exchangers.
