SolAqua thermosiphon hot water system, which will be installed on the roof-top of the building, operates on the principle of thermal siphon, when the heat transfer liquid is heated, the heated part will rise naturally and the cold part will sink, creating a state of natural circulation. This system is simple, efficient, safe, and reliable:

1. The flat plate collector absorbs solar radiation energy and heats the antifreeze/heat transfer fluid. The density of the fluid 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 transfer heat to the domestic water in the tank
3. After heat transfer, the temperature and density of the fluid decrease, and it returns to the flat plate collector.
4. The heat transfer fluid will be heated again and rises into the jacket layer of the water tank, and transfers the heat to the domestic water again. By doing so, the solar radiation energy is transferred to the domestic water until the water in the tank is heated to the set temperature

As the system works according to the thermal siphon, there’s no need to install any additional circulation pump, and only to make sure the pipeline from the solar water storage tank to the solar collector drops more than 10° continuously to ensure the normal 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 requirements of the system and the annual ambient temperature is not less than 0 ° C, a direct circulation system can be installed. Please contact sales consulting to select a suitable system.
