ABSTRACT:
A combination fireplace enclosure and heat-exchanger unit for providing supplemental heat to areas external to the fireplace. The unit includes an enclosure frame having double-paned glass closure doors, and a steam-heating system disposed at the upper portion of the frame. The heating system comprises a boiler device mounted at the rear of the frame and above the fire, and a heat-exchanger device disposed at the front of the frame. The heat-exchanger device has a steam passage which is connected by a steam line to the boiler. The passage is sloped with respect to the horizontal, such that condensate from the exchanger device can flow by gravity back to the boiler device to be converted into steam. The entire system is vented to the atmosphere whereby there is no danger of pressure build-up; accordingly the need for relief valves is obviated. Means providing an inlet to the system enable measured quantities of water to be added periodically, as required. The enclosure and heat-exchanger unit are completely self-contained, and accordingly can be readily installed with a minimum of tools, and with no external plumbing connections being required.
