ABSTRACT:
A fireplace heating system is provided which may be arranged to heat with unique efficiency the room in which the fireplace is situated and/or any desired number of additional rooms within the capacity of the system. The system is characterized by the fact that air is collected from the top of the room or rooms being heated where, though still warm, it has, because of its location, lost its capability of serving the occupants. The air so collected is transmitted downward through a heat exchanger in which the hot products of combustion from the fireplace are traveling upward. The air thus reheated is distributed to the involved rooms either at floor level, or from beneath the floor. It is a significant feature that the recycled, breathable air, while being driven downward through the heat exchanger, is kept separated from the products of combustion. It is nevertheless maintained in intimate heat exchanging relation with such products by causing such products to travel upward in the heat exchanger, through several heat conductive tubes of relatively small cross-section and therefore of relatively large surface area in relation to flow capacity. A remotely controlled, variable speed fan is desirably employed for driving the collected air downward through the heat exchanger. The air is returned in large volume but at moderate velocity and at a temperature which is comfortable to the human body.
