ABSTRACT:
A fireplace heating and cooling system is disclosed which heats air in a forced air heating system and heats water for a circulating hot water heating system or for hot tap water when combustion occurs in the fireplace and alternately will cool the air in a central, forced air system by circulating water cooled by a heat sink, through heat exchangers. A water reservoir is mounted on top of a fireplace firebox, having a central passage formed therethrough communicating with the throat of the firebox for absorbing heat from the combustion gases to heat water stored in the reservoir. A valve means selectively connects the water reservoir to a pressurized water supply, with an outlet to a circulating hot water heating system or to hot water taps. An air plenum is formed around the reservoir for circulating air from the ambient, across the reservoir to transfer heat between the water and the air. A heat exchanging element is connected to a heat sink such as subterranean soil, through which water is circulated by means of a pump and is selectively connected by the valve means to the water reservoir. After combustion has occurred in the fireplace, air can be warmed in the plenum for space heating and the water in the reservoir can be warmed for circulating hot water heating or for hot tap water when the valve means connects the pressurized water supply to the reservoir. Alternately, air can be cooled by circulating it through the plenum when the valve means connects the reservoir to the water circulating through the heat sink. In this manner, the system which is used as a heater in conjunction with the fireplace in the winter time, may also be used as an air conditioning cooler in the summertime.
