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. The temperature difference between day and night is significant. During the day, the solar water heater is most likely to explode. The temperature in the vacuum tube alternates between hot and cold, and there is a big difference. local pressure, which can cause pipes to burst.
In short, whether it is an electric heating tubeFor solar water heater or 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.

In order to make solar energy a continuous and stable energy source, and ultimately an alternative energy source capable of competing withconventional energy sources, the problem of energy storage must be well solved, that is, energy from solar radiation. in clear weather it should be stored as much as possible. It can be used at night or on rainy days, but energy storage is also one of the weakest links in solar energy use.

1 Reason 1: There is no water in the water tank and in the solar vacuum tube. is exposed to air. The temperature inside the tube can reach around 2500°C, and it is easy to burst the pipe. 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 a solar pipe,which can effectively prevent the 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 an electric heating tube for a solar water heater or an electric heating tube for other liquids, it cannot not 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.

Daily maintenance
1. When installing a heateron solar, there may be a smell of dust or oil in the water line. You can open it when using it for the first time. Remove the debris from the faucet first.
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. The surface of the solar water heater 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.
