Title:
WATER HEATER
Document Type and Number:
Japanese Patent JP2019095159
Kind Code:
A
Abstract:
To secure tapping capacity in a hot water supply circuit even when the hot water supply circuit and a circulation circuit are simultaneously used in a one-can and two-water channel type water heater.SOLUTION: Whether simultaneous use of a hot water supply circuit and a bath circuit is started or not is confirmed by determination in S1, and in a case of the simultaneous use, a controller executes reheating by changing setting of a rotating speed of a pump from 6000 rpm as a rotating speed for single use to 1000 rpm in S2. As a water passing amount ot a bath heat exchanger is reduced by lowering of the rotating speed, and a heat quantity obtained by a hot water supply heat exchanger is increased, tapping at a set temperature can be performed without largely lowering a tapping amount in tapping control in the hot water supply circuit. When OFF of a bath water flow switch is confirmed after the termination of the reheating in S3, the controller returns the setting of the rotating speed of the pump to 6000 rpm for single use in S4, and executes normal control in S5.SELECTED DRAWING: Figure 2
