Abstract: A water saving device includes a housing having a hot water inlet chamber connectable to a hot water supply, a temperature sensing chamber having a cold water outlet connectable to a water storage system, and a hot water outlet chamber having a hot water outlet. The inlet and outlet chambers are interconnected by a first port. The inlet and temperature sensing chambers are interconnected by a second port. The temperature sensing and hot water outlet chambers are interconnected by a third port. The device includes a water-pressure actuated piston that is displaceable upon a drop in water pressure in the hot water outlet chamber. The temperature sensing chamber has a temperature-sensitive valve assembly that closes the third port when the temperature of water is below a predetermined level and opens the third port and closes the cold water outlet when the temperature of water is above a predetermined temperature.

Abstract: A water saving device (1) for a hot water discharging means, said device comprising: a housing having a hot water inlet chamber (5) having a hot water inlet (2) connectable to a hot water supply, a temperature sensing chamber (6) having a cold water outlet (3) connectable to a water storage system, and a hot water outlet chamber (7) having a hot water outlet (4) connectable to said hot water discharging means. The hot water inlet chamber (5) and said hot water outlet chamber (7) being interconnected by a first port (8), said hot water inlet chamber (5) and said temperature sensing chamber (6) being interconnected by a second port (9), and said temperature sensing chamber (6) and said hot water outlet chamber (4) being interconnected by a third port (10).
