The reasons why water is not hot in solar water heaters are:
1. There is an obstruction in front of the water heater and the sunlight duration is short;
p>2. The upper and lower water valves are not closed tightly;
3. The water quality is poor and there is scale in the vacuum tubes, reducing the efficiency of heat collection;
4. The local air pollution is serious, and there is dust on the surface of the vacuum tubes, which affects the heat collection;
5, all the hot water in the tank water is exhausted, that is, there is no basic water temperature, the capacity of the water tank is small, and the water consumption is large;
6.
The solutions are as follows:
1. Remove obstructions or relocate solar energy
2. Replace the water supply ball valve;
p>3, cleanez the vacuum tube;
4. Rub the surface of the vacuum tube and the focusing grid;
5. Replace the large capacity water heater or install electric heating; system
6, Analyze the weather conditions and pay attention to the amount of water supplied to the water heater.
Note: If you encounter the above situation, do not disassemble it yourself. You should contact professional after-sales personnel.
First, check whether the circulation pipeline between the flat plate collector and the water tank is installed correctly. In a natural circulation system, the circulation pipeline should move gradually upward without reversing slopes up and down. circulation system. The height difference and distance between the water tank and the collector cannot be too large, otherwise the heat loss will be relatively large. Second, observe the duration oflighting. In winter, the lighting duration is short and the sun angle is low. If other obstacles are added, it will definitely affect the water temperature. Third, if the product quality of the flat sensor is acceptable, especially the thermal insulation performance, the ambient temperature is low in winter, and if the thermal insulation performance of the flat sensor is not up to standard, all the heat solar absorbed will be. will be lost and the water temperature will certainly not increase.
