Analysis of the reasons why the solar water heater does not produce water:
1. The water in the water tank has been emptied. It must be filled with water and heated in the sun. Before use. The upper and lower water valves are leaking, the water supply valve is also leaking, and the water pipe has been dry for a long time, causing water to flow back. This situation requires repair.
2. Sewer pipes, valves or joints are leaking and sewer pipes need to be repaired: The pipes of solar water heaters are installed outdoors and are exposed to wind and rain for a long time. are easily weathered and corroded; or valves, there are signs of loosening at the joints, etc. These reasons will also prevent the home solar water heater from producing hot water;
3. The tap water pressure is high and hot water cannot flow. You need to reduce the flow rate of the eto the tap or install a booster pump. In winter, water pipes can freeze. It will melt on its own about 3 hours after sunrise. In cold areas, a drain valve can also be installed.
4. The sensor is not installed in a correct position and the solar water shows that it is full even though it is not. You can suck water from the solar water tank into a transparent plastic tube and see how far the water level is in the plastic tube from the overflow. If the difference is too big, there is a problem with the sensor. If this is not the problem, a person may be consuming too much water.
Are solar vent holes installed in your house on the side? It may happen that when installing solar power, the solar power is not placed smoothly, that is, the left and right are not at the same level (e.g.example, left is higher and right is lower). The exhaust hole in the water tank is lower than the overflow pipe, so water flows out of the exhaust hole instead of the overflow pipe. It goes through the overflow hole, right?
