Title:
WATER HEATER
Document Type and Number:
Japanese Patent JP2013238374
Kind Code:
A
Abstract:

To provide a water heater capable of resolving poor circulation of hot-water/water.

A water heater for supplying hot water to a bathtub 61, includes a pump 24 disposed in a pipe 27, a detecting means 21, and a control means. The pipe is applied to circulate hot-water/water in the bathtub through a heat exchanger 26 for heating. The pump circulates the hot-water/water. The detecting means detects whether a flow rate of the hot-water/water in the pipe is a certain rate or more, or not. The control means increases a rotational frequency of the pump when the certain flow rate or more is not detected by the detecting means regardless of an operation of the pump.
