ABSTRACT:
An auxiliary heating system for providing energy to a furnace and a domestic hot water heater. A heat transfer fluid is contained within a storage tank and is automatically routed between a heat exchanger located in an auxiliary heater, such as a fireplace or a wood burning stove, and a furnace as typically employed in a home or the like. The furnace may be a forced air system or a hydronic boiler system. In response to the sensed condition of the fire within the auxiliary heater and the demands of the furnace control thermostat, the heat transfer fluid is automatically circulated through one of a plurality of flow circuits so that the available energy contained in the fluid is used in the most efficient manner. A preheat coil is immersed in the storage tank through which domestic water is passed prior to its being delivered into the water heater.
