<p>PROBLEM TO BE SOLVED: To provide a technology capable of accurately informing a user of the necessity of heating by using a second heating source in a hot water supply system that includes a tank for storing hot water heated by a first heating source and the second heating source for heating the hot water to be sent from the tank to a hot water supply portion.SOLUTION: A hot water supply system includes: a first heating source for heating hot water; a tank for storing the hot water heated by the first heating source; hot water temperature acquisition means for acquiring a temperature of hot water that can be supplied from the tank; a second heating source for heating hot water to be supplied from the tank to a hot water supply portion; and a display device for displaying a system state including tank hot water storage amount. In the hot water supply system, when the temperature of the hot water that can be supplied from the tank is higher than a reference temperature on the basis of a hot water supply set temperature, the display device indicates the system state in a first display form, and when the temperature of hot water that can be supplied from the tank is lower than the reference temperature, the display device indicates the system state in a second display form.</p> |
