Open loop solar water heaters: (Direct system without heat exchanger). Developed for warm countries with no freezing risk. The sun’s heat is transferred directly to the potable water circulating through the collector and into the storage tank.
Closed loop solar water heaters: (Indirect system with heat exchanger). There is an external heat exchanger in the tank. Heat is transferred to the potable water through the heat exchanger in the lower portion of the storage tank. Inside the heat exchanger is a glycol formula that prevents freezing of the potable water. Click here for diagram.
