Structural classification of solar water heater:
1) Compact solar water heater: Insert the vacuum glass tube directly into the water tank, and use the circulation of heating water to increase the temperature of the water in the water tank. This is the most conventional solar water heater in the market.
2) Split-type water heater: Split-type water heater separates the collector from the water tank, which can greatly increase the capacity of the solar water heater, and does not adopt the falling water working method, which expands the scope of use.
