Active Space Heating
Solar energy collectors generate active space heating in two separate forms – solar air heating and solar water heating. Both types of active space heating systems are very reliable and can supplement forced air systems, solar water heating can supplement heat for in-floor radiant.
However, solar air heating is easier and requires a lower amount of investment to install; and is more often recommended.
A solar forced air system simply draws the air from the home - or any type building - into the collector, the sun heats the air, then a blower draws that heated air back into the structure. Home Power Magazine Article
The collectors that GreenSky promotes and installs have some special adaptations: one are dividers that force the air to serpentine through the system for 2 benefits - it will "scrub the corners", utilizing the entire collector heating surface, and plus, the air will stay longer in the collector obtaining a higher temperature. Another is a special absorber coating called TINOX. It is titanium based and comes from Germany. This coating is the highest efficient material available on the market - 97 percent efficient.
Also, this specialized solar air heater is equipped with a copper absorber plate located directly behind the 6000 pounds per square inch tensile strength solar glass. The space between this 4' x 8' copper sheet and corresponding solar glass is sealed.
Your air actually circulates behind the copper absorber plate for 2 benefits - condensation on the inner glass, often associated with cooler air being warmed, is not in contact with the air from your space. Also, copper is anti-bacterial, insuring you peace of mind.
