EPL Pressurized Solar Hot Water System
EPL Non-pressurized Solar Hot Water System
  Non-Pressurized Solar Water Heating System
  The simplest systems are the non-pressurized or passive solar water heaters. They are most commonly used in Asia and Africa regions which do not experience extensive periods of below freezing temperatures. The water in these solar collectors circulates without the aid of pumps or controls.

When the sun shines on the collector panels, heat is absorbed by the water in the collector. As the water heats up, it starts to rise up the pipes, in the same way that hot air rises. When it gets to the top of the collector panel, it flows out of the panel and back into the storage tank. Colder water from the bottom of the tank then flows down to the bottom of the collector panels. Water continues to cycle through the system, and on sunny days can easily exceed the temperature required for home hot water.
