ABSTRACT:
A supplemental heating system for incorporation into the flue of a conventional home furnace includes an inner pipe section and a sleeve concentric with that pipe section, which sleeve has a diameter appreciably larger than that of the pipe section so as to form an annular space between the pipe section and the sleeve. Plates are provided between the pipe section and the sleeve to close off the ends of that space and a blower is arranged to discharge air through an opening in the sleeve wall into that space. Additional openings through the sleeve at locations away from the blower opening are provided to make connections to ducts leading to one or more hot air registers. The blower is arranged to operate with the furnace so that it is only turned on when the pipe section is heated whereby air discharged by the blower into the annular space is heated and conveyed through the registers to living spaces.
