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.

  • Hartgard anti-freeze, anti-corrosion fluid
  • Nothing clogs or corrodes the inside of the panels
  • HarSat overheat protection as standard
  • Suited to regions with variable temperatures
