Oil heater and electrothermal?film are the pure resistance circuit, using resistance heating, its efficiency is not much difference. Oil heater is heated slowly, it can have a slow heat dissipation for a period of time after power off, the electrothermal?film is heated quickly, it can immediately cool off after the power off. But there is not much difference when the power is same. Thermal power and consumption are same. The size of electrothermal film is a little small, it do not occupy the room. I recommend the electrothermal?film
Electric heater is also called electric?heater with oil charge. The electric heater is filled with a new type of heat conducting oil, when the power supply is switched on, the heat conducting oil around the electric heating tube is heated, and then the heat is distributed along the heat pipe or the scattered piece. electrothermal?film electric heater uses all transparent high temperature electrothermal?film as the heating material, it is the advanced level in the process in the world.
