Abstract
Abstract The present invention includes a heating system for use with a primary source of heat, such as a gas hot air furnace, or the like. A first conduit formed with perforations therethrough conveys hot exhaust gases generated by the furnace to a flue. A second conduit carrying a fluid is coiled about the first conduit in close proximity thereto so as to permit a transfer of heat to said fluid from exhaust gases escaping from said perforations and contacting said second conduit. A third conduit houses the first and second conduits and conveys exhaust gases that have escaped through said perforations to the flue. Sleeve means intermediate the first and second conduits control the rate of said heat transfer.

A method of utilizing primary heat generating apparatus to provide supplemental heat to a preselected area, comprising the steps of: conveying a predetermined quantity of an exhaust medium discharged by said apparatus along a first path in a first conduit means; conveying a fluid in a second conduit means along a second substantially closed-loop path, a portion of which is substantially proximate said first conduit means; pre-heating said fluid; causing predetermined first escaping exhaust quantities of said exhaust medium to escape from said first conduit means at first predetermined spaced locations along its length and to come into contact with said second conduit means, thereby causing a transfer of heat from said exhaust medium to quantities of said fluid; causing predetermined second quantities of said exhaust medium to escape from said first conduit means at second predetermined locations along its length intermediate said first predetermined locations and to come into contact with sleeve means which cover portions of said first conduit means; conveying heat received by said sleeve means from said second escaping quantities of the exhaust medium from said sleeve means to said second conduit by means of conduction and convection and radiation; conveying said heated fluid quantities to an area substantially remote from said apparatus; permitting heat acquired by said heated fluid quantities to be transferred to said preselected area; and returning said fluid which has lost said heat to the preselected area to said position of proximity with respect to the first conduit means influencing the flow of escaping exhaust medium so as to control the rate of the transfer of heat from said exhaust medium to said fluid, said step of influencing including imparting a non-linear motion to quantities of said escaping exhaust medium, said step of imparting a non-linear motion including doing so by means of a plurality of vane members of substantially uniform height and curved configuration.
