Abstract

Abstract An improved heating system is disclosed including a heat-generating means and plenum, a conventional ducting system interconnecting the heat-generating means to one or more air discharge registers, particularly characterized in the utilization of a heat exchanger adjacent the heat-generating source and a heat exchanger adjacent the air discharge register, with said heat exchangers being interconnected by a heat-conducting tube carrying a quantity of thermally conductive liquid so as to utilize the improved conductivity of the liquid to minimize heat loss between the heat-generating source to the register. The invention discloses utilization of the heat-conducting tube either externally or internally of a conventional ducting system. Further, the tube is disclosed in a modification as being comprised of a plurality of segments interconnected by a slip-joint or sleeve which controls the transfer of heat between adjacent segments of the tubing. Another form of the invention is also disclosed wherein the first heat exchanger is in the heat-generating source, the conventional ducting is disposed with, and the register is connected directly to the heat-generating source by the heat-conducting tube. In this form of the invention blower means are provided adjacent the air discharge outlet.
