GEOTHERMAL ENERGY BASICS
Geothermal energy is renewable heat energy from the Earth.
It's clean and sustainable
Geothermal Energy is the heat (thermal) derived from the
earth (geo). It is the thermal energy contained in the
rock and fluid (that fills the fractures and pores within
the rock) in the earth's crust.
The use of geothermal energy is not limited to heating,
but can also be used for cooling, humidity control and
even water heating. When heating, the earth acts as a
heat source, when cooling it acts as a heat sink.
Applications of geothermal energy:
To create electricity or to provide direct services, such
as hot water heating or warming of green houses.
Using the thermal mass of soil or ground water to drive
a heat pump, which can be used for either heating or cooling
applications?
These are known as geothermal ground source heat pump
applications.
Ground -source heat pumps use the earth
or groundwater as a heat source in winter and a heat sink
in summer. [ Using resource temperatures of 4°C (40°F)
to 38°C (100°F).].
Geothermal heat pumps tap the resources of the earth's
crust to heat and cool buildings.
What is a Geothermal Heat Pump?
Geothermal heat pumps are self-contained electrically
powered systems that take advantage of the earth's relatively
constant, moderate ground temperature to provide heating,
cooling, and domestic hot water at a substantial savings
in the monthly energy
bills.
A geothermal heat pump system consists of a heat pump,
an air delivery system (ductwork), and a heat exchanger—a
system of pipes buried in the shallow ground near the
building. In the winter, the heat pump removes heat from
the heat exchanger and pumps it into the indoor air delivery
system. In the summer, the process is reversed, and the
heat pump moves heat from the indoor air into the heat
exchanger. The heat removed from the indoor air during
the summer can also be used to provide a free source of
hot water.
With buried pipes in the ground to move heat either in
or out of the home. The system provides you with space
heating and air conditioning, thus giving you ear-round
comfort to any climate condition.
How much does a Geothermal system use electricity?
Geothermal systems use electricity, in a way that benefits
the customers.
