Electric heating film is a semi transparent polyester film that can generate heat after being electrified. It is made by processing and hot pressing conductive special ink and metal current carrying strips between insulating polyester films. When working, electric heating film is used as the heating element to radiate heat into the space, making the human body and objects warm first. Its comprehensive effect is better than traditional convection heating method. The low-temperature radiation electric heating film system consists of a power supply, a temperature controller, connectors, an insulation layer, an electric heating film, and a decorative layer. The power supply is connected to the electric heating film through wires, converting electrical energy into thermal energy. Due to the pure resistance circuit of the electric heating film, its conversion efficiency is high. Except for a small loss (2%), the vast majority (98%) is converted into thermal energy.

The development potential of electric heating film is enormous, which is in line with the trend of low-carbon economic development. The electric heating film heating method does not consume water, does not occupy land, has independent switching, saves energy and materials, conforms to the policy orientation of emission reduction and low-carbon, and has broad development prospects. The promotion and application of electric heating film technology can not only improve energy efficiency, but also reduce environmental pollution caused by traditional heating methods. With the continuous advancement of technology and the reduction of costs, electric film heating systems will become more popular and bring users a more comfortable and convenient heating experience. With the increasing demand for quality of life, electric film heating, with its unique advantages, will become an important choice in the future heating market.
