If electric heating is not used, it is a good thing that the temperature of solar energy is always high. It's an effect that many people dream of. However, since it's solar power, that means you have to have some. the capacity of the sun. If your local sun is always high, Very good, it is normal that the solar energy temperature is always very high. If there is no solar energy and the solar energy temperature is still very high, it means. that your solar energy uses electric auxiliary heating, because cold water does not heat up without reason. Check Have you started the electric heating?
I hope you will adopt it. Thank you
< h3>Why is the temperature in the solar water heater so high in summer?The solar water heater has not discharged high temperature hot water since a long time. There will be no damage. However, if the solar water heater is not pas cleaned for a long time, there will indeed be some water pollution problems and some damage to the skin. It is recommended to drain the water if not used for a long time.
The solar water heater itself changes the temperature of the water as it heats. Now that the temperature is high, the water in the water tank is still heated. It is natural for the temperature to be high when there is no cold water supply. Solar water heaters have an exhaust pipe that vents steam and reduces the temperature of the water tank. If the exhaust pipe is not blocked, there will usually be no problem. The best water heaters will have similar overheat protection devices to prevent overheating. water tank from exploding.
If the solar water heater is not cleaned in time and used for a long time, it is harmful to people, because theThe water quality has deteriorated and bacteria has grown, which will cause some damage to the skin. Therefore, the water contained in solar energy must be used frequently. When buying you should be careful. The larger the capacity, the better. You should choose the solar energy volume according to your own situation and the number of people. to ensure that solar water is used in one day.
Precautions for use
1. Drain the water if you do not use it for a long time. Evacuated tube solar water heaters have high heat absorption efficiency. On sunny summer days, the water temperature in the water heater can reach boiling point in less than two days. If there is no water for a long time, the water tank will remain in a state of high temperature and pressure, which will promote the aging of the seal ringand will accelerate the aging and shrinkage of the insulating material - polyurethane. Sometimes the exhaust does not flow properly. Too high pressure will cause the water tank to swell and scale, shortening its lifespan.
If the original tap water quality is poor, the water heater is stopped for a long time, and the water in the water tank is not drained, the Affected pipes connected to the water tank will rust easily. The switch may not be closed tightly and the water tank may not be closed tightly. Therefore, when a family is away from home for a long time, they need to arrange for other people to frequently drain the water from the water heater or drain the water from the water heater before going out, or place a cover on the vacuum tube collector to block the sun then remove it after returning home.
2. Reasonably understande time of water supply. Although an unoccupied solar water heater will not be damaged by the sun, if water is added to a water heater exposed to the sun, the vacuum tube will still burst. Therefore, the timing of filling the solar water heater should be reasonable.
Firstly, when the solar water heater is filled with water for the first time or the water tank is out of water for more than 15 When you get into the water in a few minutes, be careful not to get in the water during the day. The best time to get in the water is before sunrise in the morning or around 10 p.m. in the evening. Since the vacuum tube can reach 270 to 400 degrees Celsius without water, if cold water is suddenly added, the vacuum tube will burst due to the sudden drop in local temperature.
Second, do not be careless when filling the solar water heater when it is not empty. In summer, it isIt's best not to fill the solar panel with water after 9 am. In winter, you should try not to replenish solar energy at night to avoid freezing and solar energy damage due to low temperatures. Additionally, the amount of water should be determined based on weather conditions to ensure appropriate water temperature during bathing. If the weather is nice the next day, fill it with water; if it is cloudy or cloudy, fill it with half a tank of water; if it rains all day, keep the original amount of water without adding cold water.
Will the water temperature in the solar water heater be too high to burn the machine?
Due to the high temperature in summer, the solar collector vacuum tube absorbs too much sunlight, causing the water temperature to be too high. It can reach boiling point. At this point you should not add water or add lwater to the solar water heater. If you fill the water at this time, it will easily damage the machine and the solar water. pipe.
During use, the water temperature is too high in summer. Be sure not to let children use the water from the solar water heater alone, because without staff supervision, the water temperature is too high and the user can easily be burned. Even adults need to pay attention to this.
Actually, it is normal for home solar water heaters to reach 99 degrees in summer, because the sun's ultraviolet rays are strongest in summer, the light energy absorbed by solar collectors is the highest value of the year, and the high temperature resistance of vacuum tubes can reach When the temperature is about 250 degrees or more, as long as the water is not replenished here, it will have no impact on the solar water heater, so don't worry. Use it simnormally.
The highest water temperature in a solar water heater is 100°C. From the first stages of the design of the solar water heater, the problem of combustion and aging of the components was taken into account. water heaters will not burn out.
However, it is recommended not to maintain high temperatures permanently. If the temperature remains high for too long, it will accelerate the aging of the water tank coating and various accessories. Therefore, it is recommended that when the solar water heater is not used for a long time, the automatic water supply function should be turned off or the water in the solar water heater can be drained.
