SolAqua thermosiphon solar hot water system operates on the principle of thermal siphon, and the system is simple, efficient, safe, and reliable:

1. The flat plate collector absorbs solar radiation energy and heats the antifreeze/heat transfer fluid. The fluid density decreases when the temperature increases and goes up naturally.
2. The heat transfer fluid goes through the copper tube inner circulation into the jacket layer of the water tank, then transfers heat to the domestic water in the tank.
3. After heat transfer, the fluid’s temperature density decreases, returning to the flat plate collector.
4. The heat transfer fluid will be heated again, rises into the jacket layer of the water tank, and transfers the heat to the domestic water again until the water is heated to the set temperature.

As the system is worked according to the thermal siphon, there’s no need to install any additional circulation pump. Only to make sure the pipeline from the solar water storage tank to the solar collector drops more than 10° continuously to ensure the regular operation of the system.

Depending on the different operating environments of the system, the user can choose a direct circulation system or an indirect circulation system. When the water quality meets the system’s requirements and the annual ambient temperature is not less than 0 ° C, a direct circulation system can be installed.
