In 2014, China's energy consumption still ranked first in the world, accounting for 21.5% of the world's total energy consumption; at the same time, my country's energy is relatively short, and energy waste is very serious. At present, common equipment in the household heating market has problems such as low safety factor, large size, low electrothermal conversion efficiency, backward technology, poor user experience, and poor energy-saving and environmental protection performance.

PTC electric heaters can well solve the above problems due to the characteristics of PTC components, such as long natural life, automatic constant temperature, no open flame, high reliability, and remarkable energy-saving effect. Its automatic constant temperature function is manifested in: when the PTC heating element is energized, the temperature is low, at this time the resistance is small, the power is large, and it can be heated rapidly. When the temperature gradually rises to around the Curie temperature, the resistance increases sharply by 3 to 7 Order of magnitude (10 ³ to 10 ⁷ times). At this time, under the action of constant voltage, the current passing through the element decreases, and the temperature of the corresponding element is in a balanced state. When the temperature of the PTC heating element decreases for some reason, its resistance value decreases, which in turn leads to an increase in the current passing through the thermistor element. Large, the temperature of the component rises, so that the temperature reaches an equilibrium state again. By repeating the above process, the PTC heating element itself can automatically adjust the output power, so as to achieve the purpose of automatic temperature control.
