1. The heating wire is used in a closed space. When the heating wire is energized and heated, the surface of the heating wire is charged. The heating tube can be used in any electric heating environment, air or liquid;
2. The surface of the heating wire is conductive, and the surface of the heating tube is non-conductive, but the heating wire is easy to operate, and the operation of the heating tube is complicated;
3. The electric heating wire is closely related to the electric heating tube. The electric heating wire is the raw material of the electric heating tube. The cost of the electric heating wire is lower than that of the electric heating tube.
