Solar Domestic Hot Water Systems
Solar Energy – A Popular Energy Source
For most Americans, solar energy is a preferred energy source. Clean and
renewable, solar energy reduces worldwide dependence on fossil fuels and
their inherent environmental and political problems. Plus, the cost of
harnessing the sun’s energy is independent from rising energy prices.

Solar Thermal for Your Home - Generating and Using Heat Locally
With a solar thermal system, the energy for your hot water and heating
is generated locally from your roof. Your hot water needs determine what
your optimal size system would be. Larger systems simply use more
collectors and larger water storage tanks.

Solar Energy for the
Future
Solar
energy is clean, reliable, reduces energy costs,
and is promoted by attractive subsidies. Thus, solar offers an
attractive alternative to coal, gas, nuclear, and oil as sources of
energy.
Solar Thermal - Heat from Solar
Energy
The basic principles of solar thermal are easy to grasp: Unroll a
garden hose and lay it out in the sun. After a while the water in the
hose will get hot.
Thermal collectors work on the same principle, only much more
efficiently. A special fluid is heated within a closed circuit to a
temperature of up to 430 degrees Fahrenheit and pumped into a heat
exchanger to transfer the heat without mixing fluids. This heat is then
"stored" in a domestic hot water tank. Some solar thermal systems are
used to merely heat a home's domestic hot water, while others are used
for heating or even to heat swimming pool water.
Heat Even When It Is Cloudy
Heat will still be generated even when the sun is obscured by clouds.
Even on cloudy days, thermal systems work with a large percentage of
their capacity through the diffuse light they receive.
