PURPOSE: A heating system for hot water, a method for detecting existence of water in the hot water heating system, and a water purifier with the same are provided to detect the existence of water and prevent heating in case there is no water inside the heating system for hot water. CONSTITUTION: A heating system for hot water comprises a case(61), a cylindrical heater(62), a spiral flow path(63), a temperature sensor(64), a contact spring(65), and first and second electrode sensors(68,69). An inlet is formed on the side of the case and an outlet is formed on the top of the case. The cylindrical heater is arranged inside the case by passing through the outlet. The spiral flow path is connected to the inlet of the case and formed facing the lower part of the cylindrical heater. The temperature sensor is arranged in the inner lower part of the case. The contact spring is installed between the cylindrical heater and the temperature sensor. The first electrode sensor is installed near the inlet and the second electrode sensor is installed near the outlet. |
