Its working principle is to make a mica heating body by gluing and pressing the heating resistor piece by layer by layer of mica material. After power on, it realizes heating by forming a triple method of hot air curtain, thermal convection and far-infrared heat radiation.

The volume of this heater is slimmer than that of an electric oil heater, and the heating method takes into account the characteristics of the above-mentioned heaters, and the appearance is also a more fashionable flat plate, which is more in line with the aesthetics of modern people.

It is different from fan heaters such as Little Sun. Because mica board heaters are surface heating, their biggest advantages are fast temperature rise, strong failure resistance, no electromagnetic pollution, and uniform heating. Compared with electric oil heaters, it has certain advantages in heating speed and energy conversion efficiency.
