Abstract
Abstract Apparatus for providing more efficient use of heating and/or cooling sources as used within a building structure, particularly residential type buildings. In essence, this system utilizes a wood-burning fireplace in coactive conjunction with a standard form of building heater system, gas, oil or the like, and it functions to provide an integrated system having greater efficiency, and therefore greater fuel conservation. The fireplace includes a plurality of heat exchange chambers through which ambient air is pulled by the central system blower for subsequent recirculation through the heat register or release vents and, as temperature controls will dictate, central system heat may or may not be additive therewith. More efficient cooling is effected in like manner by coaction of a cooling system with the fireplace plenum chambers to provide a continual source of cooled air for contributive use with the central cooling system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
198 words
An auxiliary fuel burning temperature control apparatus for use in a building enclosure in combination with a central furnace and blower system, comprising: first chamber means having a front opening and defining a fireplace with a continuous volume of chamber around the rear and both sides, said chamber having air intake vents proximate the bottom of each side and an air exhaust vent proximate the top of the rear; means for enclosing said first chamber means front opening to close said fireplace; second chamber means of generally cubical form for secure affixure on top of said first chamber means, said second chamber means including a plurality of rows of flue pipes extending vertically therethrough and into communication with said fireplace, said second chamber means including lower lateral air intake vents and upper exhaust vent; manifold and chimney means securely affixed over the top of said second chamber means; means for introducing air into said first chamber means fireplace from external to said building enclosure; and duct means for conveying conditioned air from said upper exhaust vents of each of the first and second chamber means to said central furnace and blower system for distribution within said building enclosure.
