Closed circuit
Solahart is the only brand in the world to have developed the closed-circuit system for its water heaters. The “Hartgard” fluid circulates in a jacket around the storage cylinder: nothing can clog or corrode the inside of the panels, and the fluid protects the system from both freezing and overheating.
