A movable electric heater is provided to heat a wide space at a uniform temperature, reduce a product price by simplifying the heater structure, and reduce maintenance cost. A movable electric heater includes a casing(10), an electric heat generating body(20), a power supply(30), a temperature sensor, and a control unit(40). The casing has an air inlet part formed at a lower region, a heat discharge port formed at an upper region, and a roller disposed at the lower region. The electric heat generating body is installed in the casing between the inlet air port and the heat discharge port, and has a heater and a heat radiation part. The power supply supplies power to the heater. The temperature sensor is installed in the casing. The control unit compares a temperature detected by the temperature sensor with a predetermined temperature to control the heating operation of the electric heat generating part. |
