What is Geothermal?
What is a Geothermal Heat Pump?
GEOTHERMAL HEATING & COOLING – the
GREEN way to heating & cooling your home or
business!
Geothermal heating, also referred to as geoexchange,
geothermal heat pumps (GHPs), ground-source heat
pumps (GSHPs), and water source heat pumps is one of
the most efficient ways to heat and cool a home. More
and more homeowners are discovering the benefits of
these systems, which tap the relatively constant
temperature of the Earth.
Simply put, in winter, warmth is drawn from the earth
through a series of pipes, called a loop, installed
beneath the ground. A water solution circulates through
the loop and carries the earth’s natural warmth (in North
Carolina the earth stays at a relatively constant
temperature of approximately 62 degrees) to a heat
pump inside the home. Geothermal vertical loop diagram.
The heat pump concentrates the earth’s thermal energy
and transfers it to air circulated through interior ductwork
or to radiant heat in flooring.

In the summer, the process is reversed; heat is extracted
from air inside the home and transferred to the biggest
“heat sink” of all- Earth – by way of geothermal loops.

Also, as an added bonus you can utilize the waste heat
removed from the home’s interior during the cooling
season to provide virtually free hot water. This can result
in a total savings in hot water costs of about 30%
annually, and further lower your home’s total emissions.
Geothermal can also be used in conjunction with solar,
radiant floor systems, as well as used to preheat
domestic hot water.
Who Can Use Geothermal?
Geothermal systems can be found in all types of structures from residential
housing to commercial buildings. From new construction to existing
structures, luxury homes and middle-class homes to townhomes and condos,
geothermal systems are becoming a valuable option.
More builders are
seeking geothermal technology to increase energy efficiency and
reduce their ‘carbon footprint’. Benefits that conventional heating
and cooling systems just can’t match.
Geothermal systems are a cost effective, energy efficient and
environmentally friendly way of heating and cooling buildings.

Geothermal systems have numerous benefits. Geothermal will:
  • Save energy
  • Save money by lowering utility bills
  • Cut greenhouse gas emissions
  • Reduce noise

SOME GEOTHERMAL HISTORY!
Geothermal Heat Pumps have been in use since the
1940s. Their popularity has gone up along with
upwardly spiraling utility prices, including electricity,
heating oil, and natural gas. Geothermal Home Heating
