ABSTRACT:
A heat transfer device for transferring excessive waste heat from the upper portion of a fireplace to the room comprising a high temperature heat exchanger positioned above the fire grate between the fire and the flue of the fireplace. A mass transfer tube communicates between the heat exchanger and the low temperature heat exchanger positioned above the lintel on the fireplace. A heat transfer fluid is secured within the hollow high temperature heat exchanger such as trichloromonofluoromethane such that as the fluid boils, the heat of the fire the liquid turns to a gas and moves through the mass transfer tube to low temperature exchanger. The fluid cools and gives up its heat to the low temperature exchanger which in turn gives up the heat to ambient air. As the fluid cools, it becomes a liquid again and flows back down the transfer tube from which it came to the high temperature exchanger. If desired, a blower may be provided to force air across the low temperature exchanger to provide a more efficient exchange of heat.
