ABSTRACT:
A combination fireplace enclosure and heat-exchanger unit of the retro-fit variety, for providing supplemental heat to room areas external to a fireplace, comprising an enclosure frame having closure doors, and a series of elongate heat-transfer members carried by the frame and constituted of relatively high thermally conductive material such as aluminum, disposed side by side, and having portions extending rearwardly from the frame in a position directly above the fire so as to absorb heat therefrom. Other portions of the members extend forwardly through an aperture in the frame and terminate as a series of spaced-apart radiating fins of relatively large expanse and disposed at the front of the frame. Air from the room is thus heated by these fins, through conduction and radiation. A ventilating hood is provided, to partially conceal the fins and shield them from inadvertent contact with personnel in the room. A baffle carried by the frame directs hot gases from the fire toward and past the absorption portions of the members, to maximize heat-transfer thereto. The closure doors carried by the frame minimize heat loss from the room, due to air therefrom being drawn up the chimney. As a result, there is realized higher heating efficiency than was possible with other heat-extracting units of the type intended to be used with fireplaces.
