Geothermal systems have many benefits as compared
to "conventional" systems - furnaces or boilers with air cooled condensing
units and refrigeration piping circuits for cooling.
Lower Operating Cost
A geothermal system operates
more efficiently than ordinary heating and air conditioning systems because
it can deliver an astounding five units of energy for every one unit of
electrical energy used. One unit of energy put into the heat pump
(electricity) plus 4 units of energy pulled from the earth (geothermal
energy) yields 5 units of energy output for heating and cooling! This,
by the way, is a 500% efficient system, or in heat pump terms, a 5 COP -
coefficient of performance. By combining stored earth energy with safe
electric power, many geothermal system owners realize savings up to 70% for
heating, cooling and hot water.
Enhanced Comfort
Geothermal systems provide precise distribution of comfortable air all year
long, eliminating hot spots and cold spots. During heating, you'll
experience warm air without the hot blasts associated with ordinary gas
furnaces, or the cooler air of an air source heat pump. Additionally, when
cooling, our geothermal units deliver cool, dehumidified air.
Reliable
Unlike air conditioners and heat pumps, geothermal units are installed
indoors (like a refrigerator), so they are not subject to wear and tear
caused by rain, snow, ice, debris, extreme temperatures or vandalism.
Geothermal units have proven to be very reliable and require less
maintenance.
Quiet
Unlike ordinary air conditioners or heat pumps, there is no noisy outdoor
unit to disturb the outdoor environment or the neighbors. Geothermal heat
pump units are designed and constructed for "whisper quiet" operation,
similar to a refrigerator.
Environmentally Friendly
According to the Department of Energy and the EPA, geothermal systems are
the most environmentally friendly way to heat and cool a house. Our systems
emit no carbon dioxide, carbon monoxide or other greenhouse gases which are
considered to be major contributors to environmental air pollution. In
addition, there is minimal ozone layer destruction due to the use of factory
sealed refrigeration systems.
