1. Reason 1: There is no water in the water tank. When the solar vacuum tube is exposed to the sun, the temperature inside the tube can reach about 2500°C, 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, the solar water heater is more likely to burst when filling water. The vacuum tube alternates between hot and cold, and there is significant local pressure. This can cause the pipe to burst.
In short, whether it is a heating tubet electric for a solar water heater or an electric heating tube for other liquids, it cannot be dried without being separated from the liquid. , the internal temperature of the electric heating tube will be too high and the electric heating tube will be damaged. The pipe is burned, posing a safety risk.

Routine maintenance
1. When installing the solar water heater, there may be a smell of dust or oil in the water pipe when using it. the first time, you can turn on the tap first. Get rid of the clutter.
2. The water stored in the solar water heater should be discharged regularly according to local water quality conditions. Drain time can be selected in the morning when the sensor temperature is high. lower.
3. TheSolar water heater surface should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Cleaning the water heater can achieve higher thermal 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 it on. cold water first then hot water to avoid burns.
5. There is usually a filter device at the outlet of the faucet. Scale and debris in the water line accumulate on this screen. It must be removed and cleaned regularly. Increase the amount of water flowing.
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 automatically freed afterwards. The temperature increases.You can also use a hair dryer to blow on the water line, or wrap a towel around the water line and then slowly pour warm water over it. 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.
Cannot be used.
Some roofs or bungalows do not have lightning protection devices, and solar energy is not equipped with lightning protection devices. When used during stormy weather, solar energy can act as a lightning rod. energy can threaten user safety and equipment safety.Complete.
Although you bring your own paratrooperlightning when installing solar power or whether you choose to install it within the effective range of the lightning protection device, there is still a certain degree of danger, so do not use it
