Solar Heat kits/Energy saving Product

To estimate the size of a FreeHeat Solar Collector array that would work for you, divide the number of square feet you want to heat by 10.  For example, a well-insulated 1200 square foot house would need 120 square feet of collector surface

The thermosiphon collector consists of clear, corrugated polycarbonate panels fastened to 2-by-6-inch studs. The clear panels admit sunlight, and an absorber suspended inside the collector captures the suns heat energy. The air around the absorber warms, expands and rises, creating a convection current. Vents at the top and bottom of the collector allow air to circulate through it. Cool air enters the lower vents from the interior, is heated by the absorber, rises to the upper vents and returns to the    interior. Air circulation continues as long as the sun shines on the collector.

At night, airflow reverses as air in the collector cools to outside temperatures. Simple flapper valves on the top vents stop this reverse circulation and keep the heat inside.

HOW IT WORKS

The picture above spares nothing for effeciency, but you can dress it up as much as you would like. Flat panels are avaible. Oak and Maple framing or metal frames are also available. You buy these yourself and are available everywhere.You won't change the effectiveness, but you can make it look more high tech.

Low-tech solar space heaters use sunlight as fuel during clear winter days.
FreeHeat solar space heaters pay for themselves quickly. Compared with using gas, electricity, or oil heaters, they will produce substantial savings year after year when properly installed on a southerly facing wall that gets unobstructed sunlight. 

These heaters are intended only for use as supplemental space heaters. While the sun shines, they produce lots of heat and will warm insulated spaces.  To place an order, obtain support, or get more
