1. Different structures
Fully automatic solar water heaters insert vacuum glass tubes directly into the water tank and use the circulation of heated water to increase the water temperature in the tank of water. This is the most common practice on the market. The solar water heater does not require additional switches. The semi-automatic solar water heater separates the collector from the water tank, which can greatly increase the capacity of the solar water heater. It does not use the waterfall operation method, which expands the scope of use, but requires water supply. switch to turn on.
2. The water tank is pressurized in different ways

3. The surface of the solar water heater should be wiped regularly depending on the quanity 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 water.
