Abstract
An attachment or, accessory water heater being installed in any furnace flue, or pipe giving off an exhaust heat. When installed in a flue or pipe and connected in conjunction to any type self-sufficient water heater tank. It is the purpose of this invention, to use the heat which escapes up the flue from the furnace during operation. Thus eliminating in most cases, and drastically reducing in others, the need for additional energy, which is normally used to heat water. The accessory heater is essentially a condensed unit, which divides water into multiple and smaller parts, comprising a conduit of two sizes, being formed and shaped into condensed spiral coils, and connected to rings or headers, and circulating water through the unit and back to the tank, by means of convection or pump.
