Product Description

Non pressure solar water heater with assistant tank (8 liters), two pipes inlet/outlet system:
The non-pressure solar water heaters rely on the natural circulation of water between the collector and the tank. As water in the evacuated tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the evacuated tubes, causing circulation throughout the system. So once and once again, all the cold water will be heated gradually and become hot water. At the same time, assistant tank can replenish water automatically.

*. Cheap solution, high reliability, simple structure, easy installation.
*.   High efficiency with daily average efficiency higher than 60%.
*.   Auxiliary electric heater (1500W) and controller are optional.
