Abstract

A domestic hot water system supplying a tap 12 is provided with a water saving device 14. When the hot tap is turned on, a valve 20 in the device closes so that cooled water in pipe 10 bypasses the tap and is recirculated through return pipe 16. When hot water reaches the device the valve 20 opens to supply the tap. The device comprises a pressure switch 22 which senses that the tap has been turned on and closes the valve 20 and starts a pump 24. A temperature sensor 26 in the pipe 10 opens the valve 20 and stops the pump when the water runs hot. The device may be used to supply a washing machine with hot water. <IMAGE>
