How to install the electric heating of solar water heater
After being sure to install it when you buy it back, the first step is to turn on water and electricity after the water is turned on, so as to prevent dry burning in the new machine.
Usually, after using it, you should also pay attention to turn off the power supply and turn off the water. After a long time, you should pay attention to cleaning and cleaning the filter inside the purified water. Prevent blockage.
Replace magnesium rods. Nowadays, most electric water heaters are designed and installed with magnesium rods, which are used as sacrificial anodes in water heaters. Because the metal activity of magnesium is higher than that of iron, when the magnesium rod is exposed at the same time as the ordinary steel plate, the magnesium rod will first be corroded instead of the steel plate, so as to achieve the purpose of maintaining the inner tank.
Clean regularly. That is, after the thermal electric water heater has been used for a period of time, scale and dirt will be produced on the surface of the inner tank and heating tube, which will affect the effluent quality and greatly reduce the heat exchange efficiency. If it is not removed in time, not only electric energy will be wasted, but also the life of heating tube and inner tank will be shortened and even overheated due to poor heat conduction of heating tube. Therefore, the electric water heater should be bathed regularly.
Expansion materials:
When purchasing solar water heaters, please note:
1. See whether the number of vacuum tubes matches the water tank. The vacuum tube with a length of 1.8m can be heated by 8-10 liters. After all, the purpose of buying solar energy is to use how many liters of hot water, not the number of vacuum tubes. Nor is it that the more the number of vacuum tubes, the higher the water temperature. The number of the vacuum tube is large and the capacity of the water tank is very small, indicating that the heat collection capacity of the vacuum tube is very low.
2. Burn off the bracket with a lighter to see if the paint of the bracket is baked. The painted bracket will change color in two or three years. The bracket resembles a human skeleton.
3. 3% product, 7% installation. Installation is the key. The key to the ease of use of solar energy lies in the key. Installation should not leave room for heat preservation and anti-corrosion measures. Especially in the north, the electric tropics must be of high quality, otherwise it will cause fire and endless trouble.

How can this kind of solar energy be removed?
First drain the water, and then remove the connecting pipe to see if you want to move the solar energy or pack it! If you want to move, you can remove the water pipe and you can move it. If there is a big noise, you have to remove the vacuum tube, turn it slowly and then pull it out and pour out the water to wipe it clean and keep it clean. When it is all done, you will begin to disassemble the heat preservation bucket. Remove the clip from the bucket and slowly remove it to control the water inside, box and save it, so that the shelf does not have to be disassembled.
This is the end of the introduction of heat collector tube packing. Thank you for taking the time to read the contents of this site. Don’t forget to look for more information about container radiator and heat collector pipe packing in this site.
