摘要： PROBLEM TO BE SOLVED: To securely prevent water works from being contaminated by a latent heat storage material by providing heat storage units capable of detecting the degree of risk of damage to heat transfer tubes due to corrosion.
SOLUTION: This water heater 10 comprises heat source units 20 and 30 and the heat storage units 40 and 50. The heat transfer tubes 45 and 55 for heating and the heat transfer tubes 46 and 56 for hot water delivery are connected to the heat storage units 40 and 50. The material of the heat transfer tubes 45 and 55 for heating is copper which is the same as that of the heat transfer tubes 46 and 56 for hot water delivery, and their wall thicknesses are thinner than those of the heat transfer tubes 46 and 56 for hot water delivery. When the thin-walled heat transfer tubes 45 and 55 are damaged due to corrosion before the heat transfer tubes 46 and 56 for hot water delivery are damaged, a leakage detection part 81 detects refrigerant leakage from refrigerant circuits 21 and 31 and output detection signals. Then, a control part 82 receives the detection signals and closes a solenoid valve 83 to cut out a hot water supply circuit 60 from the water works before the heat transfer tubes 45 and 55 for heating are damaged.
