Provided is a technology to enable users to accurately grasp whether hot water was heated by a second heating source in a hot water supply system, wherein the hot water supply system includes: a tank which stores hot water heated by a first heating source; and the second heating source which heats the hot water to be sent to hot water supply points from the tank. According to the present invention, the hot water supply system comprises: the first heating source to heat water; the tank to store the hot water heated by the first heating source; a hot water temperature acquisition unit to acquire the temperature of hot water to be supplied from the tank; the second heating source to heat the hot water to be sent to hot water supply points from the tank; and a display device to display the condition of the system including the hot water storage amount of the tank. In the hot water supply system, the display device displays the condition of the system in a first display manner when the temperature of the hot water to be supplied from the tank is higher than a reference temperature based on a hot water set temperature; and in a second manner when the temperature of the hot water to be supplied from the tank is lower than the reference temperature. |
