Abstract:
The object of the SMITH WATER SAVER is to save and use the water in the hot water line, between the hot water heater and the faucet. When the user opens the hot water faucet, unheated water in the line begins to circulate back to the water heater in a return line. Ahead of the faucet is a throttle or thermocouple which while closed allows the unheated water to recirculate until it reaches a desired temperature (displayed by an indicator), at which time the throttle is opened, or a thermocouple opens automatically, and hot water flows out of the spigot.
