Document Type and Number:
Japanese Patent JP2844328
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To keep hot water discharge temperature within 3 deg.C even when a discharge water flow rate is slightly increased, e.g. one shower is opened from a stopped state of hot water discharge, in discharging to a plurality of shower heads hot water heated by a water-to-water heat exchanger. SOLUTION: In this apparatus, boiler water heated in a boiler body 12 by a burner 11 is made to effect heat exchange with water supplied through a supply water inlet 21 within a heat exchanger 19 to feed hot water to a circulation pump 17 controlled by using a temperature adjusting device 29 and an inverter 30, which pump supplies the hot water to a plurality of shower heads from a hot water outlet 24. A water supply pipe 22 and a hot water supply pipe 22a are connected with each other by interposing a bypass pipe 31 opened and closed by a solenoid valve 32. Opening-and- closing of the solenoid valve 32 is controlled by the temperature adjusting device 29 and a board 34, which are connected to a hot water temperature sensor 26 and carry out proportional, integral and differential controls. If hot water discharge temperature detected by the hot water temperature sensor 26 exceeds a set temperature, the solenoid valve 32 is opened to add water through water supply pipe 22 to the hot water in the hot water supply pipe 22a to suppress a hot water temperature rise.
