Open the CIPO recordAbstract From the Canadian patent
The present invention relates to flue-mounted power heat recuperators designed to transfer heat from flue gas through metal to air. In this invention a heat reflecting flexible sleeve encloses a metal flue of low emissivity forming a "tube-within-a-tube" heat exchanger and heat is reclaimed directly from the outside surface of the said flue by means of counterflow or parallel-flow forced air convection. The above arrangement provides air of higher temperature and when combined with a central home-heating forced air furnace it increases temperature of supply air and enhances efficiency of the whole central home-heating system.
