Working principle
The non-pressurized system is based on the natural circulation-thermosiphon phenomenon. It's the most cost-effectiveness and environmentally friendly way to harness solar energy for hot water applications, which is unsurpassed by any other solar thermal products, for its most high efficiency, low cost, easy installation.
