Heating your home's hot water is one of the most energy consuming demands for your home.
The cost of heating water in your home is likely
to be 25 - 30% of your total energy costs, but
can be even higher if you have more than
four people in your home. Almost half of your
electric bill, or more than 40% of your gas or oil
bill, may go towards your domestic hot water
costs. Solar water heating is the easiest way to
utilize the sun's energy to conserve fossil fuel
and save money. A residential solar hot water
system will reduce the energy you require to heat your hot water anywhere from 50 to 80%!
How Your System Works Heating your home's hot water is one of the most energy consuming demands for your home
Evacuated Tube Collectors
Pumping and Control Stations Solar Hot Water Storage Tanks
In conventional water heating, cold water is fed
from the city supply or your well into the gas or
electric water heating where it is heated to a design
temperature of 120 degrees Fahrenheit. With your
solar hot water system, cold water is fed into the
solar storage tank. The pump circulates a non-freeze
fluid through the solar collectors where it is heated
by the sun. The heated fluid is pumped into the
heat exchanger in the storage tank where the heat
is then transferred to the water. The Regusol 130
EL continually monitors the temperature of the fluid
in the collectors and the temperature in the tank. If
the fluid in the collectors is warmer than the water
in the tank, the pump circulates the fluid through
the collectors. The Regusol 130 EL switches off
automatically when there is insufficient sunlight
and the collectors are no longer able to raise the
temperature in the storage tank. This happens when
the sun is at a very low angle, when there is a thick
cloud cover, and at night. The pump automatically
starts again when enough sunlight is available.
Temperatures in your solar storage tank can be as
high as 120°F in winter to 150°F in the summer
months. When you turn on a hot water faucet in your
home, solar-heated water requires very little or no
heating to reach your desired temperatures.
Your solar hot water system is used in conjunction
with your existing water heating system, to provide
the additional heat required to bring your solar heated
water up to your desired temperature. The
existing system also sustains hot water demand
during winter and prolonged cloudy weather or when
you have visitors in your home.
