That won't happen. Generally speaking, solar collector tubes can be exposed to over 240 degrees, and good ones will be even higher. Therefore, vacuum tubes generally do not explode. But you cannot add water to an empty collector between 10am and 5pm when the sun is shining. Adding water at this time would easily explode. This should be later in the summer.
Why did the solar vacuum tube explode?
Two situations can cause solar tubes to burst:
1. There is a lot of sunshine during the day, lack of water in the water tank, high temperature, sudden water supply and drastic problem. temperature changes, leading to tube bursting.
2. Without regular cleaning, there is too much scale in the solar collector tube, abundant sunlight, large heating capacity, poor water circulation inthe tube, resulting in excessive local pressure, leading to tube explosion.
Are the heat-collecting vacuum tubes of solar water heaters fragile? Are you afraid of hail or something?
1. Reason 1: There is no water in the water tank. When the solar vacuum tube is exposed to air, the temperature inside the tube can reach about 2500°C and it is easy to explode. . 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 exploder when water is supplied to the solar water heater. The tube alternates between hot and cold, and there is significant local pressure, which can cause the tube to burst.
In 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.
Detailed information:
1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe. When using it for the first time, you can first open the faucet to remove debris. .
2. The water stored in the solar water heater must 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 should be wiped 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 water.
6. In winterer, 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 also use an electric blower to roll up the hose or wrap it with a towel, then slowly pour warm water over it. Do not cook it on fire, hit the pipe, or scald it with boiling water, as 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.

There are two reasons for this. vacuum tube failure, explosion
External force
and improper water filling time. Byexample, if the vacuum tube is at high temperature, the water filling vacuum tube will burst at that time. time.
However, if it is fresh water, solar energy does not need to provide water every day. For example, Soller Sunshine Solar will not cause explosions.
