< p> There are standards for the selection of electric heating tubes, as they must be able to resist dry burning. If the quality is poor and the heating wire is exposed due to dry burning cracks, it will cause electrification in the water. At presenther, if you take a bath, it is easy to cause leakage and injury. If the problem occurs, you should generally choose Yinglai 800 electric heating tube, which can withstand dry heating for 72 hours without deformation. the price is much more expensive than ordinary electric heating;

Thawing refers to the electric heating belt (also called anti-freeze belt), the choice of this heating belt is also very critical if the connection of the heating belt is. not good, it will cause electricity to be connected and burn the pipe insulation. This has happened several times in the market. It is also necessary to choose hot melt adhesive sealing technology and conductive copper core. the material should not be less than 0.2mm. Any thickness less than this value does not comply with the standards.

Tubes 4 and 20 are inserted into the tube75.

The numbers on the heating rod are divided into two types: roof and interior. The roof will display De20, which is a temperature tube separated by 20 degrees. When indoors, it will display De20, which is a temperature tube separated by 20 degrees. display De75. This 75 refers to the 4 and 20 temperature tubes interspersed with the 75 degree tube.

After the solar water heater is filled with water, it generally takes a day to heat in winter and half a day in summer. Hot water is heated and stored in the water tank.
