Electric heating elements are auxiliary components installed in solar water storage tanks to provide backup heating when solar energy is insufficient (e.g., during cloudy days or high-demand periods). These heating tubes ensure a consistent supply of hot water by supplementing the solar thermal system with electric power.

Tubular Heating Element Type:

Bend Tube Heating Element Type:

1. How to choose the size of the electric heating tube?
1) The diameter of the bottom outer hole is 55mm, please choose the 47mm electric heating tube inserted at the bottom.
2) The diameter of the bottom outer hole is 69mm, please choose the 58mm electric heating tube inserted at the bottom.
3) If the reserved hole is under the side of the water tank, please choose the side direct plug-in electric heating tube.
4) If there is the 8cm flange hole at the bottom of the water tank, please choose the flanged electric heating tube.
 
2. How to install the plug-in electric heating tube at the bottom?
1) Take out the old electric heating tube or the plug in the hole;
2) Apply detergent to lubricate the electric heating tube;
3) Turn the handle of the electric heating tube and gently push it into the hole;
4) The red wire is connected to the live wire, the blue wire is connected to the null wire, and the yellow/green wire is connected to the earth wire.

Application:

The electric heating element can not only be used as a heater for closed oil tanks, oil drums and hydraulic oil devices, but also as water tanks, boiler heaters, tank heaters, mold temperature machine heaters, etc., and are widely used in the heating of tanks equipment in electronics, plastics, chemical industry and environmental engineering.
