1. Reason 1: There is no water in the water tank, solar energy
Vacuum tube
When the tube is exposed to air, the temperature inside the tube can reach about 2500C, and it is easy to explode the tube. In winter, the pipes are exposed to the outside. When the weather is very cold, the inside of the pipes freezes and the water cannot be filled. To solve this problem, simply wrap a thick layer of sponge over the water tank pipe. or solar pipe, which can effectively prevent water from not flowing and draining the pipe and bursting the pipe.
2. Reason 2: The temperature difference between day and night is large. During the day,
Solar water heaters
are more likely to explode when filling. The water. The temperature in the vacuum tube alternates between hot and cold, causing high local pressure, this can cause the pipe to burst.
InIn short, whether it is an electric heating tube for solar water heater or an electric heating tube for other liquids, it should not be separated from the liquid and burned dry, otherwise the internal temperature of the liquid will be changed. The electric heating tube will be too high and the electric heating tube will burn out, causing safety hazards.

Daily maintenance
1 When installing a heater -solar water, inside. the water line may smell like dust or oil. When you use it for the first time, you can open the faucet first to remove debris.
2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater must be testeduyed regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smooth the flow.
6. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically after the temperature rises. You can alsoUse a hair dryer to blow on the water line, or wrap a towel around the water line, then slowly pour it with warm water. Do not cook it on fire, hit the water pipe, or scald it with boiling water, because. this will cause the pipe to burst. Multiple freeze blockages can easily cause pipes to freeze and crack. Pipe insulation measures must therefore be reinforced.
