simple technology at its best!
1. Collectors are available in three sizes: 26, 32, and 40 sq. ft.
2. Maximized by the glazed surface, the amount of sunlight that enters the collector and is trapped as heat.
3. Cool air from the building is pulled into the collector then heated and returned to the interior.
4. The temperature difference is monitored by the differential controller which is located between the panel and building. When the interior reaches your desired temperature check valves to keep unwanted hot air from coming into your home.
