The present invention relates to an apparatus to supply hot water. More specifically, an apparatus to supply hot water includes: a water purifier connected to a water supply line installed in an external hydrant to filter cold water supplied therefrom; a boiler having a lower end connected to a clean water supply line which guides clean water filtered by the water purifier to heat the clean water supplied from the water purifier; a hot water distributor connected to the water purifier with a clean water discharge line, and connected to an upper part of the boiler with a hot water discharge line; and a control unit configured to control the water purifier and the boiler, and to control the opening and closing of the clean water discharge line and the hot water discharge line wherein the boiler includes: a casing; a pressure container provided in the casing having a lower end connected to the clean water supply line, and having an upper end connected to the hot water discharge line; a heater provided in the pressure container to heat supplied clean water; a water level sensor provided on an upper surface of the pressure container to sense a water level of the supplied clean water; a temperature sensor provided on an upper surface of the pressure container to sense an internal pressure of the pressure container; a pressure solenoid valve configured to adjust the internal pressure of the pressure container; and a thermostat provided on an upper surface of the pressure container to automatically block the operation of the heater when an internal temperature of the pressure container becomes more than or equal to a predetermined temperature. Therefore, the risk of explosion of the boiler may be removed, and prevents the hot water from spattering or flying around when hot water is discharged. |
