Water heater

A water heater comprising: a hot water tank 3; a water supply pipe 12; an entering-water pipe 18; a heating device 10; and an outgoing-hot water pipe 19, wherein the entering-water pipe 18 or the water supply pipe 12 includes a main flow path 18a and an auxiliary flow path 18b which splits flow of t...

description A water heater comprising: a hot water tank 3; a water supply pipe 12; an entering-water pipe 18; a heating device 10; and an outgoing-hot water pipe 19, wherein the entering-water pipe 18 or the water supply pipe 12 includes a main flow path 18a and an auxiliary flow path 18b which splits flow of the main flow path 18a, the main flow path 18a includes a water quality adjusting portion 23, which reforms the inflow water into water having quality in which scale is less prone to be generated, and which flows the water out, a first closing valve 25a which closes a flow path and is arranged upstream of the water quality adjusting portion 23, and a second closing valve 25b which closes a flow path and is arranged downstream of the water quality adjusting portion 23. Therefore, it is possible to carry out maintenance of the water quality adjusting portion 23 which suppresses deposition of scale without stopping an operation of the water heater.
