Solar water heaters cannot be heated electrically. Working principle of solar water heater: In the hot water system, the fins inside the flat collector convert the absorbed solar radiation into thermal energy, causing the temperature of the working fluid in the tube to continuously increase. heat exchange of the collector. Advantage of the low density of hydrothermal liquid, the cold liquid has the characteristics of high density;
Through the circulation pipeline, a natural circulation of cold water up and down and hot water from bottom to top is formed between the collector and the water tank. Thanks to this cycle, the water in the water tank gradually heats up. Since the working fluid in the flat collector is a low temperature resistant liquid, it can be maintained at minus 40 degrees without freezing. So even in alpine and cold areas it can work normally all year round.
The solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet the use of hot water by people in life and production. 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.

Precautions for using solar water heaters:
1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe. When using it for the first time, you can first open the faucet to remove debris.
2. The water stored in the solar water heater should be drained regularly depending on the local conditions.ales of water quality. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smooth the flow.
