The heating body of the electrothermal?film is taking the carbon?fiber as the conductor material. which is a kind of electrical, thermal and mechanical new materials with strength is larger than steel, density smaller than aluminum, better corrosion resistance than stainless steel, better high temperature resistance than heat resistant steel, and electric conductive like copper, And due to carbon fiber electrothermal?film products is roll-shaped, the larger the room, the less the contact proportional numbers compared with that of carbon crystal contacts under the same areas. Electrothermal?film only has 4-6 contacts in the same 40 square meters living room. Greatly improving the safety of the product.
The electrothermal?film efficiency will decrease with the usage rate year by year, so it is recommended that you should be better to use oil heater according to the size of your room. The service life of oil heater is longer than that of electrothermal?film and it is more practical than the electrothermal film. You can choose Xianfeng oil heater, which is cost-effective and professional.
