Why Solar?

Solar Evacuated Tube Design


As the price of fuel rises, the coast advantage of solar becomes obvious. Solar thermal energy is free and therefore one of the most cost effective technologies on the market. With solar thermal, you can reduce your water heating bills by 50 to 75% and can supplement space heating as well!

Solar thermal collectors are up to 80% efficient in converting the sun’s energy into usable heat vs. solar electric or P.V. panels which are only approaching 20% efficient in converting the sun’s energy into usable electricity.

Along with the environmental and energy savings that come with purchasing our solar tube collectors, incentives and rebates are also available! The federal government currently offers a 30% tax credit to homes and businesses that install a solar hot water system including the installing cost. Several state and local incentives are also available throughout the U.S.

The Versatility of the Evacuated Tube Collectors

The collectors are suitable for residential and commercial applications. They can be used with the following:

• Domestic Hot Water
• Radiant Floor/Space Heating
• Solar Pool
• Spa and Hot Tub heating
• Industrial SHW Systems
• Municipal SHW Systems
• Agricultural SHW Systems

High Quality

In the event of a tube breaking, it can be removed and the entire system will continue to function, ensuring a heating source the will not fail.

Where flat plate solar collectors may be damaged, or less production in colder northern climates through the United States and around the world, Evacuated Tube Collectors shine because of their incredible freeze protection and unique 360 degree collector design.
