The most cost-effective way to use renewable technologies in your home is by incorporating solar hot water. According to the Environmental and Energy Study Institute (EESI), there are 1.5 million solar water heaters already in use in U.S. homes and businesses.
Since Solar water heater systems can work effectively in just about any climate, it’s estimated that 40 percent of all U.S. homes have sufficient access to sunlight to make it cost effective for them to install solar water heaters right now.
Domestic hot water heating can be achieved by using solar hot water evacuated hot water tube collectors. The evacuated tube collectors produce heat energy from the sun's kng wave radiation (infrared) which is able to penetrate through even the thickest cloud cover. The tubes have a collector located inside in a vacuum which is unaffected by ambient temperatures, and the medium (antifreeze/water) passes through the insulated manifold only. They can produce high temperatures for heating water - even in the middle of winter.
