It should be called a collecting tube. There are two reasons why the tube bursts: ?
The sun is good during the day and the temperature of the collecting tube is high. fills suddenly, cools too quickly and the thermal stress generated is too high. The resistance of the collector tube glass can cause the tube to burst.
There is a lot of scale buildup in the collection tube and water circulation is blocked. When the sun shines, the heat collection effect is remarkable and it is easy to boil water. generated is hampered by scale accumulation and cannot be discharged smoothly, and the temperature If the increase continues, local high pressure will occur and pipe bursting will occur.
The water heater must be cleaned and descaled regularly.
Descaling requires soaking in descaler. You can inject it through the return pipe of the water tankwith a funnel. If you don't want to go on the roof, you can purchase a set of solar water heaters online. without removing the descaling device. You can use it indoors. Injecting a descaling agent into the water heater for cleaning is simple and convenient. Cleaning it regularly after use can prevent this problem from recurring.
Why did the solar vacuum tube explode?
There are two reasons for a pipe explosion:?
1.
The sun is good during the day, the temperature of the pipe collector is high, the water fills suddenly and the cooling is too rapid, resulting in thermal stress greater than the strength of the collector tube glass and the tube bursts.
2.
There is a lot of scale accumulation in the collector tube and the water circulation is blocked when the sun shines, the heat collection effect is remarkable. He iseasy to boil water. The steam generated is affected by scale deposits. If the block is blocked, it cannot be discharged smoothly, and if the temperature increase continues, local high pressure will occur and pipe bursting will occur.
The water heater must be cleaned and descaled regularly.
Descaling requires soaking in descaler. You can inject it through the return pipe of the water tank with a funnel. If you don't want to go on the roof, you can buy a set online.
Solar water heaters do not need to be removed.
Use it to inject descaling agent into the water heater inside to clean it.
It is simple and convenient to use.
Clean it regularly after using it.
To prevent this problem from recurring.
1. Reason 1: There is no water in the water tank, solar energy
Vacuum tube
When exposed to air, the temperature inside the tube can reach about 2500C, 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,
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.
In short, whether it is an electric heating tube for solar water heater or an electric heating tube forother 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 solar water heater, there may be a smell of dust or oil in the water pipe. When you use it for the first time, you can open the tap to. remove the debris first.
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 should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Guardr clean water heater surface 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 be frozen. If the pipe is found to have frozen but not yet cracked, it can usually be cleared automatically after the temperature rises. You can also use a hair dryer to blow on the water line, or wrap a towel around the lineof water, then slowly pour it with lukewarm 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.
