In most homes today, when a person turns on a hot water faucet, he or she must wait for residual cold water to flow out of the hot water pipe as hot water travels from the water heater to the faucet. That residual cold water typically goes down the drain. In some buildings, recirculating hot water systems keep hot water flowing in a loop, thereby making hot water immediately available and eliminating the waste of residual hot water, but these systems waste energy from thermal radiation in the hot water pipes at times when no hot water is being utilized. The invention conserves both water and energy by controlling the recirculation of residual cold water by means of momentary activation of any hot water faucet, and also by programmed time-of-day intervals, whereupon the pump replaces the residual cold water with hot water and recirculates the residual cold water, and then turns off so as to avoid energy waste from running hot water through the loop at times it is not needed. The invention provides for fast installation of the pump, detector, and controller on the hot water outlet side of the water heater. It can be used in buildings that have separate hot water return pipes, and it can also be used in configurations where existing cold water pipes are used for the return of hot water.

The system is unique in that a structure's plumbing lines are effectively routed, to stop energy and water waste, while adding little to construction cost. Water pressure to hot water supply (50) is controlled through a selectable flow control valve (10). A hot water manifold (3) and check valves 42 and 43 produce a dual line connection, between hot water manifold (3) and the hot water use area. In the water saver mode, positioning selectable flow control valve (10) causes pump (4) to draw water from distribution conduit (6), through selectable flow control valve (10), through cold water manifold (12) and solenoid valve (37) to hot water supply (50). Pump (4) causes hot water to fill distribution conduit (6), to the hot water use area. This circulation delivers hot water to replace water standing in the line. Circulation period is determined by controller (22). When selectable flow control valve (10) is positioned to the use mode, supply pressure at cold water conduit (28) is applied through selectable flow control valve (10), then via cold water manifold (12), to hot water supply (50). Positioning selectable flow control valve (10) to the energy saver mode causes, cold water pressure to be interrupted to hot water supply (50) and directed through feedback conduit (72) and conduit (71), to a junction down stream from hot water manifold (3). Supply pressure forces hot water towards open hot water outlet (45), thus all hot water delivered from hot water manifold (3) is utilized.
