| A
major source of energy is right under your feet.
Your own backyard has the potential to be your
source of heating and cooling comfort. Now you can get safe,
reliable, energy efficient heating and cooling from one piece
of equipment. Geothermal energy represents the leading edge
of heating and cooling technology. It moves heat energy to
and from the earth to heat and cool your indoor environment.
And compared to ordinary systems, geothermal technology can
save you 30% to 60% on your monthly energy
bills. Geothermal is the safest, cleanest, most reliable space
conditioning system you can buy.
Geothermal energy is an unlimited resource . The lot surrounding
a home contains a vast reservoir of low temperature thermal
energy, typically 10 times that required over an entire heating
season. This resource is constantly resupplied by the sun,
the surrounding earth, and heat rejected while cooling during
the summer. The universal definition of geothermal is "...pertaining
to the heat of the earth." By using the earth to provide
up to 50% of a building's total heating and cooling needs,
these systems are truly geothermal energy made practical.
Four
Basic Types of geothermal energy resources
Four
times the efficiency:
A geothermal system uses the Earth's thermal
properties in conjunction with electricity to provide
unprecedented
efficiency. For every unit of electricity the system uses,
it provides four units of heating energy, giving a geothermal
system a 400% efficiency rating on average. These numbers
translate into real savings on your utility bills year-round. |

Pond
(lake) loops are very economical to install when a body
of water is available, because excavation costs are
virtually eliminated. Coils of pipe are simply placed
on the bottom of the pond or lake. 
Open
loop systems are the fourth type and utilize ground
water as a direct energy source. In ideal conditions,
an open loop application can be the most economical
type of geothermal system
