In order to ensure the safety of solar vacuum tubes, it is best to fill the water in the morning before sunrise or 2 hours after sunset.
It is strictly prohibited to fill the solar panels with water at midday to avoid sudden changes in water temperature in the vacuum tubes that could cause an explosion.
Reason: When the solar vacuum tube dries without water (that is, it dries in the air), the temperature can quickly reach240°C or even more. When water is added, the temperature can quickly reach
240°C or even higher. the temperature difference is too large, which can easily break the vacuum tube, although the water temperature in the tube is not too high during normal use (generally between 50-90°C), to extend the life of the vacuum cleaner. tube, it is best to refill the water at night or early morning the next day.

It is strictly forbidden to fill the solar tube with water at noon to avoid rapid changes in water temperature in the vacuum tube causing the tube to explode.

When the solar water heater lacks water, water can be supplied at night in winter.
When the temperature is not lower than 5-7℃, after using water that night, if there is still hot water in the water tank , the solar water heater should be filled with water to reduce the water temperature. in the water tank and loss of heat that night. If the temperature is low, it is advisable to turn on the water the next morning to prevent the pipe at the outlet of the water heater from freezing.
Solar water heaters convert solar energy into thermal energy and heat water from low temperature to high temperature to meet people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainlyt used, representing 95% of the domestic market share.

Precautions for using solar water heaters:< p >The best time to get in the water is at night or in the morning. On a sunny day, when the water is filled for the first time or the water tank is empty for more than 15 minutes, the water cannot be refilled during the day, otherwise the water will be dried out. 'open air without water.If a high temperature of 270 degrees occurs, the vacuum glass tube will suddenly burst when exposed to cold or the vacuum tube will become scaled.
Regularly check whether the pipes, vents and other components of the water heater are functioning properly.
When not in use, the hot water nozzle and water supply valve are closed. While bathing, simply open the water valve, close the water supply valve et adjust the hot and cold water nozzles. When only water is supplied, simply turn on the water supply tap.
