Raymond Hunter - Chattanooga TN

International Classification:

F24H 300

US Classification:

165 47

Abstract:

A heat exchanger disposed in the piping of the drain line of a shower bath closet for conducting heat from the spent shower bath water to the water entering the cold water inlet of the shower bath. The heat exchanger has at least two concentric helical coils through which the incoming water flows and over which the spent bath water flows. A central core baffle directs the spent water between the helical coils for good transfer of heat. The spent water preheats the incoming cold water thereby reducing the amount of hot water required from the water heater.
