<p>PURPOSE:To enable not water having initial desired temperature to be got by a method wherein an end hot water feeder is arranged at the downstream side of a hot water source and each of the outlet part of the end hot water feeder and the water feeding pipe is connected to a mixing valve. CONSTITUTION:An inlet part 11 for hot water to be supplied from a water heating source 2 is arranged at the lower part of an end hot water feeder 9, and an outlet part 12 for hot water to be discharged from the end hot water feeder 9 is arranged at the upper part of the end hot water feeder. The inlet part 11 and the outlet part 12 are communicated to each other by a bypass pipe 13 and mixed at the primary mixing point 13a. A thermostate type automatic mixing valve 14 in which a flow rate mixing ratio is automatically adjusted to a desired temperature is arranged, a temperature sensor 14a is arranged downstream side of the final merging point 14b between the hot water and the water, and the hot water metering part 14c is arranged upstream side of the hot water inlet part 11 of the hot water feeder 9, and the water metering part 14d is communicated with the water feeding pipe 6 provided with the water feeding valve 7. A flow passage resistance passing in the end hot water feeder 9 arranged in parallel between the inlet part 11 and the outlet part 12 of the end hot water feeder 9 and the flow passage resistance passing through the bypass pipe 13 are made substantially the same to each other.</p> |
