[Solving Means] A hot water supply apparatus according to the present invention has water-softening means 30 including at least a pair of electrodes 32A and 32B, a pair of water-splitting ion exchangers 33 each having a positive ion exchanger 33A and a negative ion exchanger 33B, a flow path 34 which is in contact with the water-splitting ion exchangers 33, and an inlet 35 and an outlet 36 which are in communication with the flow path 34, and heated hot water is guided into the water-softening means 30. Maintenance of the apparatus is unnecessary, a configuration of the apparatus is simple, the apparatus can be reduced in size, and the apparatus can softens raw water having high hardness and restore with low power consumption. |
