When there is no water in the solar water heater, the vacuum tube will dry Even in winter, when the sun is good, the high-efficiency vacuum tube drying temperature can reach over 100 degrees. . So it will be hot. If this happens for a long time, it will damage the solar water heater. It is recommended to use it continuously and avoid drying it out.
Under normal use with sunlight, the water in the solar water heater is several degrees higher than room temperature or room temperature. According to the evaporation of water and the law of conservation of energy. Water vapor is always present, provided you carefully observe the position of the vent. You will notice that water vapor is still projected.
Detailed information:
When the solar water heater isAt 99 degrees, the water inside has boiled and the water vapor will be sprayed through the overflow opening. It is normal to have some noise, but most will not be heard indoors. Go to the roof to see if your home's solar is installed in a location that might resonate with the house.
Solar water heaters use sunlight to heat water, then use the principle that hot water floats and cold water sinks to create microcirculation in the water and transform cold water into hot water required. Today's solar water heaters have a wide range of applications. Solar water heaters currently on the market are technologically advanced, economical and durable.
If the solar water heater is not filled with water, will it be damaged by the sun in summer?
Solar water heater Long-term water in the air will generally not cause any harm.mmages caused by the sun but will cause damage. First of all, if stainless steel liner is used, it will deform the liner and reduce its volume. This may even cause sensors, overflow pipes, electric heaters and other components installed inside the liner to move due to deformation of the liner. lining, making solar energy unusable. If it is a brand name sunscreen, prolonged air drying will damage the collector tubes and rubber sealing rings.
This will have an impact.
1. It is not good to dry solar vacuum tubes in the air, because the temperature of the inner wall of the vacuum tube can reach 400 degrees. In this way, bad vacuum tubes will explode directly in the air. The sun. Good vacuum tubes like Linuo will reduce their lifespan, for example. They can be used for twenty years, but air drying will cause co-effects.llect of heat and changes in the molecular structure of the film, thus reducing the lifespan.
2. If you do not use it at the moment, it is recommended to cover the vacuum tube with felt, carpet or quilt to avoid sunlight, so that there will be no problems. Air drying the other parts will not pose a problem.
3. Evacuated tube solar water heaters are very efficient on sunny summer days, the water temperature can reach boiling point in less than two days if the water is not used for a long time . When traveling or traveling, the water tank will stay at high temperature for a long time. Under high pressure, it will promote the aging of the seal ring, accelerate the aging and shrinkage of polyurethane, and sometimes the exhaust is not too smooth. high pressure will cause the water tank to swell and scale, thereby shortening the hardlife of the water tank.
4. Therefore, if you are not at home for a long time, you should ask someone else to visit you regularly. Pour hot water into cold water or place a lid on it. the vacuum tube collector to block the sun, then take it off when you get home. If it is not used for a long time in winter, you should cancel the electric heating setting to avoid wasting electricity.
Detailed information
Maintenance methods of solar water heater:
1. Pay attention to the water supply time.
2. Depending on the weather conditions, determine the amount of water to ensure the appropriate water temperature during bathing.
3. Check regularly to see if the pipes, vents and other components of the water heater are working properly.
4. Rinse the ace pipes regularlypiracy in dry areas with heavy air pollution or strong sandstorms.
5. Once the water heater is installed. Non-professionals should not easily move, load or disassemble the machine to avoid damage to key components.
