First, pay attention to the water time, don't go to the water at noon. Due to the strong summer light, the vacuum tube is exposed to the sun, and the temperature in the tube is as high as 270 ° C ~ 400 ° C. At this time, the water is likely to cause the vacuum tube to burst. Therefore, when going to the water, you must choose to do it in the morning or at night. Second, according to the weather conditions, the amount of water should be determined to ensure the proper water temperature during bathing. Look at the sky water: according to the weather forecast to determine the amount of water, you can get a satisfactory water temperature. If it is sunny tomorrow, you can fill the water; if it is cloudy or cloudy, it will be in the upper half of the box; there will be rain all day, and the original water will not be cold. Third, it is necessary to regularly check whether the water heater pipe, vent hole and other components are working properly. Regularly check the vent hole to ensure smooth flow, so as not to swell or pump the water tank; when cleaning the vacuum tube, be careful not to damage the tip end of the vacuum tube; the solar water heater with auxiliary electric heating device should pay special attention to the water supply to prevent dry burning. In summer, there are many users who replace the upper and lower water pipes of solar water heaters. Experts remind users to check whether the solar water heater insulation layer is aging or cracking. If the upper and lower water pipes are exposed, under the sun's exposure, it will become hard and brittle, cracking and leaking. Users should install insulation layer and UV protection tape in advance to protect the water pipe.
