PURPOSE: A fan heater system is provided to stably be operated regardless of the external temperature by installing an electric heat storage tub on the front of the heat pump system. CONSTITUTION: A fan heater system comprises a heat storage tub(17), a heat pump system(18), and a blowing system(19). The heat storage tub comprises the water tank(20), an electric heater(21), a temperature sensor(22), a low level sensor(23), a control system(24), a piping, and a circulation pump(26). The electric heater heats the water of the water tank. The temperature sensor measures the temperature of the warm water. The low level sensor measures a water level of the water tank. The circuit controlling the temperature of the warm water and water level and electricity is installed on the control system. The piping connects the water tank and the heat pump system. The circulation pump compulsively circulates the warm water. The heat pump system comprises a warm water-air heat exchanger(27), a compressor(27), an evaporator(29), an electronic expansion valve, and an electric circuit control system(30). The electric circuit control system controls temperature and pressure of refrigerant. The blowing system comprises a blower(31) and a control system(32). The control system controls the air volume. |
