Many families are using solar water heaters. Solar water heaters are not only environmentally friendly, but also more energy-saving. What are the precautions when using solar water heaters in summer? You can check the following points:
1. Precautions for the use of solar water heaters in summer: protection of hoses
Due to the high temperature in summer, the water temperature in the water heater may also reach 70 or 80 degrees. This temperature will soften the hose and rupture. Therefore, the water heater should not be overfilled in summer, and one-third of the space should be reserved. Add cold water before the water, which can cool the water well, so as to prevent the water temperature from being too high and damaging the hose.
2. Precautions for the use of solar water heaters in summer: water heater water supply time
When the weather is extremely hot and the water temperature is extremely high, it is strictly forbidden to add water immediately after the water is used up. Because of the strong sunlight in summer, the solar energy pipes will be exposed to the sun, and the air temperature can reach 270-400 degrees. At this time, the water can easily cause the pipe to burst. It is best to water the water before sunrise in the morning or two hours when the sun sets in the evening, so as to ensure the service life of the solar water heater.
3. Precautions for the use of solar water heaters in summer: determine the water supply according to the weather conditions
According to the weather forecast to determine the water supply, a more satisfactory water temperature can be obtained. If it is sunny tomorrow, you can fill the water; if it is cloudy or cloudy, the upper half tank of water; there will be rain all day, keep the original water without cold water.
4. Precautions for the use of solar water heaters in summer: cold and hot water adjustment
The water temperature adjustment steps of solar water heaters: first open the cold water valve, adjust the flow of cold water appropriately, and then open the hot water valve to adjust until the desired bath temperature is obtained. When taking a bath, if the water in the solar water heater has been used up, and the person has not rinsed it out, you can use cold water for a few minutes, using the principle of sinking cold water and rising hot water to push out the hot water in the pipe, and you can continue After taking a shower; if there is still a little hot water in the solar water heater after taking a shower, use cold water for a few minutes to wash one more person; in addition, be careful not to face the body when the water temperature is adjusted to avoid scalding. .
5. Precautions for the use of solar water heaters in summer: sun protection
If the water heater is not used for a long time, it will cause the water in the water tank to stay for a long time, and if the water tank is at a high temperature for a long time, the aging speed of the thermal insulation layer will be accelerated. Therefore, the vacuum collector tube should be properly shielded and removed when it is used again.
The final step is to check regularly. Regularly check the vent holes to ensure unobstructed, so as not to damage or sample the water tank; solar water heaters with auxiliary electric heating devices should pay special attention to the water supply to prevent dry burning without water. In summer, there are many users who replace solar water pipes. Check whether the solar water pipe insulation layer is aging or cracked. If the water pipes are exposed, they will become hard and brittle under the sun, cracking and leaking. It is best for users to install an insulation layer and anti-ultraviolet tape in advance to fully protect the water pipe.
