How to increase the temperature of the electric heating tube?

The surface temperature of the electric heating tube depends on the surface load of the electric heating tube. What is the surface load for reference: What is the surface load of the electric heating tube?

The greater the surface load of the electric heating tube, the higher the surface temperature of the heating tube.

In order to increase the temperature of the electric heating tube, it is necessary to increase the surface load of the electric heating tube, increase the surface load, and increase the power of the electric heating tube.

For example, it was 5KW before. If you want to increase the temperature of the electric heating tube, you can customize it to 8KW.
