Abstract

PURPOSE: To improve the convenience of usage by providing n sets of hot water supply devices and n sets of water supply devices, mounting n-1 sets of back flow preventive devices with a hot water supply circuit in the same direction, reducing the minimum supply device number to the device number available to one set of hot water supply device, and increasing the maximum supply device number by n times.
CONSTITUTION: For example, it is assumed that a hot water supply device 1 is designed to supply hot water at a fixed temperature with a gas instantaneous heater whose type ranges from No.16 to No.2. A water supply pipe 3 is connected with gas instantaneous heaters 1 and 2, and hot water supply pipes 9 and 10 are supplied with them respectively. A connection pipe 11 is connected between the hot water supply pipes 9 and 10 and a back flow preventive device 12 is mounted so that hot water may flow from the hot water supply pipe 10 to the hot water supply pipe 9. This construction makes it possible to supply hot water to a washstand at the capacity of Model No.2 to No.16, if a faucet 13 is closed when a faucet 14 is opened. When the faucet 14 is closed, if the faucet 13 is opened, hot water can be supplied at the capacity of Model No.4 to No.32, but the gas instantaneous heater 2 first reaches a water quantity to put out fire due to the flow passage resistance of the back flow preventive device 12, thereby supplying hot water substantially at the capacity of Model No.2 to No.32.
