1. Double , overheating/fuse protection: The built-in temperature fuse reacts quickly and automatically cuts off the circuit when the temperature is too high. When the temperature fuse senses that the machine is not working properly and the output is overheated, it will immediately cut off the circuit to effectively prevent accidents. 2. Rapid temperature control, when the set temperature point is not reached, the resistivity is very low. Once the set temperature point is exceeded, the resistivity suddenly increases, causing the current to drop to a stable value, achieving the purpose of automatic temperature control and constant temperature. 3. Energy-saving and efficient This is a very energy-saving indoor space heater. Three seconds of rapid heating, more even heat distribution. The power level can be adjusted according to personal needs, saving energy costs. You don' have to waste a lot of money on central heating. 4.
