Free Maintenance

No glycol, simple structure. No annual and periodical check-ups or maintenance is necessary. Blind sleeve design, no pollution, no-leaking heat pipe, easy installation. No water in vacuum tubes, one broken tube will not affect the function of the whole system.


High Performance

With the cutting-edge vacuum-tube collecting technology, over 92% of sunshine energy is converted to thermal energy for heating and no circulation loss. Thicker insulation layer, functioning well in winter, even in minus-30-degree environment.


High Reliability

System is simply working with the city net water, without pumps. Inner tank made by stainless steel SUS316-1.2mm. Working with high pressure, directly connected to running water, automatically functioning. With T/P valve and exhaust valve, it protects the tank from shrinking.


Year-round Operation
