RECYCLED!

Solar Hot Water/Heating Thermal Energy Capture Tubes...gently

used by Uncle Sam!

These are the evacuated vacuum thermal Solar collector tubes. 46

inches long, by 2.0 inches diameter. Water flows in thecentral tube and collector space surrounded by two outer tubeswith a vacuum between them. The water gets so hot that it will boil, so water must be kept moving by a circulation pump. Maximum

temperature is about 250 degrees F. Hot enough to heat your homewith a hydronic radiator system, or heat your domestic hot water.

Each tube captures approximately 80-150 watts or

300-450 BTU/HR.

Works even in the coldest climates!
