ABSTRACT:
An on demand, remotely activated, electronically and electro-mechanically controlled, energy saving, water conservation, hot, water recovery system, which may be installed in residential and commercial structures having a pressurized water supply (11). The system is comprised of a dual chamber, dual hot water outlet, water heating reservoir (23), and a flow control and recovery apparatus (10), in fluid communication with a cold water supply (11) and hot water outlets (93-97). The system installs in new or existing structures, without alteration of the plumbing lines or electrical wiring. The flow control (84) is preprogrammed to, upon command, drain standing water from the hot water outlets (93-97), and refill the outlets with hot water from the small chamber (23b) of the water heating reservoir (23), making hot water available at the instant an outlet is opened. During hot water use, the system delivers hot water to the hot water outlets (93-97) from the large chamber (23a), of the water heating reservoir (23). Discontinuance of hot water use, for a time, causes the flow control (84) to configure the recovery apparatus (10) to return hot water in the hot water outlets, before it cools, to the small chamber (23b). The recovery apparatus (10) refills the empty hot water outlets with cold water, then resets to the ready condition. The system may be configured for use with any conventional water heater.
