1. When the water in the water tank is full and heated, the cold water flows and the hot water floats, forming convection. During convection, the water surface will sometimes be higher than the upper end of the overflow pipe, and the overflow pipe will drip. In addition, water droplets formed after condensation of water vapor will drip from the overflow pipe, so there is no need to suspect that the water heater is faulty. ?
2. Check the water tank and temperature. The water tank includes a heated vacuum glass tube part and a water tank body. If the temperature is always at 100°, the water will overflow quickly and slowly. Check in 2 aspects:
1. Do not fill with water. 3/4 is enough, then check if there is any water flowing.
2. When the temperature in the water tank does not exceed 80°. Look again. There is a cooling process in the tuyto the overflow, from the water tank to the end. The temperature you tested was cold water. Depending on the water droplets, sometimes fast and sometimes slow, it must be due to overflow.
3. When the water in the water tank is full and heated, the cold water flows and the hot water floats, forming convection. During convection, the water surface will sometimes be higher than the upper end of the overflow pipe, and the overflow pipe will drip. In addition, water droplets formed after condensation of water vapor will drip from the overflow pipe, so there is no need to suspect that the water heater is faulty. ?
4. If you are filling the water manually, check to see if your water supply valve is not properly closed. If the water supply valve is leaking slightly, the water tank will likely be too full and overflow.
5. When the overflow pipe is filledof water, the water will flow. The float switch will disconnect the water supply circuit and the flow will stop after a period of time. If water flows continuously, the solenoid valve is not working.
1. When the overflow pipe is full of water, it will leak when adding water. Additionally, on sunny days, water will leak due to condensation produced after the water boils.
2. After the solar water tank is filled with water, when the solar tube meets sunlight, the temperature rises and heats the water, the volume expands and overflows through the overflow pipe. You can put some water in and that will usually solve the problem.
3. The valve may be broken because you cannot visually check whether the water supply valve is good or bad. You can fill the solar power with water first, then put it in a little and wait. so that the overflow pipe stops flowing. Afters a day, if the overflow pipe drips again, indicating that the valve is broken.
Detailed information:
2. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market. share.
3. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. Conversion of solar energy into thermal energy repomainly on vacuum heat collecting tubes, which use hot water. to float and cold water to sink. According to the principle, the water will produce microcirculation to obtain the required hot water.

Causes and solutions:
1. Because the tap water pressure is too high when supplying water. process Water will splash, causing water from the tank to flow out of the vent before it is full.
Solution: Adjust the tap water pressure to standard water pressure.
2. The water return pipe is too long or not smooth, causing water to not flow out of the return pipe in time when the water is full. and if water continues to be supplied, it will flow out through other drainage holes.
Solution: This problem is a natural law and cannot be eliminated by using the return pipe. install itation of instruments can solve the problem.
3. The water supply valve or solenoid valve is not closed tightly, causing the water to fill slowly when the water is full, it will flow out of the exhaust hole.
Solution: Turn off the water supply valve or repair faulty parts.
