solar water heaters Drying may cause pipe bursts
Solar water heaters are both environmentally friendly and energy-saving, so they are favored by consumers. Although solar water heaters can bring a lot of convenience to our lives, its daily maintenance also requires us to pay special attention.
Empty exposure may cause tube burst
Usually the reason for the tube burst is that it is exposed to the sun because the solar energy often lacks water and causes overheating. He said that when there is no water in the vacuum tube, that is, in the dry state, the temperature in the vacuum tube can reach about 250 degrees Celsius. If there is no water for a long time, the vacuum tube will burst.
In addition to remembering to always water the solar energy, the time for watering is also particular. As mentioned before, the temperature in the vacuum tube can reach 250 degrees Celsius when the sun is at its maximum. If the water is flooded at this time, it is likely to cause the inside of the vacuum tube to burst. Therefore, if there is no water in the water tank of the solar water heater or for the first time watering, you must choose to water before sunrise or half an hour after the sun sets. This time is the best watering time for the solar water heater.
If the family is not at home for a long time, do not let the solar energy dry. You can fill up with water in advance or ask your neighbors to put hot water on top of cold water. Under high temperature, you can also put paper shells or other things on the vacuum tube collector to cover it.
How to extend the life of solar water heaters
Generally, a good quality solar water heater can be used for many years. If you pay more attention to some common sense of maintenance during use, you can also extend its life.
In order to prolong the service life of the solar water heater, users should pay attention to it during use. After the water heater is installed and fixed, non-professionals should not easily move or unload it to avoid damage to key components. No debris should be placed around the water heater to eliminate the impact of the vacuum tube. Hidden dangers.
On average, solar water heaters need to be cleaned, inspected, and disinfected every two to three years. Users can also do some disinfection work by themselves. For example, they can buy some chlorine-containing disinfectants and pour them into the water inlet and let them soak for a period of time. , And then released, can play a certain disinfection and sterilization effect. Adding some descaling reagents can also prevent scale formation inside the vacuum tube from affecting the heat absorption effect.
In addition, the dust and dirt on the transparent cover of the solar collector should be removed regularly, and the cover should be kept clean to ensure a high light transmittance. Regularly check whether the water tank is leaking, whether the parts are aging, whether the collector is damaged, whether the bracket is rusted, etc.
