A heat transfer system for use with a conventional fireplace for radiating heat at a remote location from the fireplace. The heat transfer system includes a network of interconnecting conduit sections charged with an internal fluid medium and consists of a plurality of coils located within the fireplace so that the fluid medium is subjected to heat generated within the fireplace. The conduit network further includes a radiant convection device for convecting the heat generated within the fluid medium to the surrounding area and an expansion tank located on a cool side of the convection device for storing a volume of the medium for subsequent redelivery to the fireplace coils. A series of first, second and third valves are located along the conduit network and separate the fireplace coils and radiant convection device, the convection device and the expansion tank, and the expansion tank and the fireplace coils, respectively. A steam inversion tube is also arrayed in communicating fashion between the inlet and outlet of the fireplace coils and functions in a first step to entrap superheated steam generated within the coils by the fluid medium and in a second step to both pre-heat return cool water from the expansion tank and to saturate the steam back to the fluid medium.
