摘要： A water heater includes a hot water tank 57, a hot water-supplying heat exchanger 52, a water-entering conduit 64, a hot water-issuing conduit 65, entering-water temperature detecting device 67, control device 83 and scale suppressing device 76. The scale suppressing device 76 includes an inlet connection port 77 and an outlet connection port 78 which can be attached to and detached from the water-entering conduit 64. The control device 83 changes an entering-water set temperature T1 at which a heating operation is completed depending upon whether or not the scale suppressing device 76 is mounted. Therefore, a lifetime of a scale inhibitor is increased, and it is possible to reduce maintenance and maintenance costs required when the scale inhibitor is replaced or replenished.
