Geothermal
Energy is heat (thermal) derived from the earth (geo). It is the
thermal energy from the earths core, which is stored in
the rock in the earths crust. Ground-source heat pumps use
this diffuse low temperature resource which is available everywhere.
The
heat pump, a device that moves heat from one place to another,
transfers heat from the soil to the building in winter and from
the building to the soil in the summer.
All
geothermal heat pumps operate without the need for flames or combustible
gas and are therefore a safe choice, requiring minimal inspection
and maintenance.
Using
a small amount of electricity to move stored heat from the ground,
or in reverse, to move excess heat from your home back into the
ground during the cooling season, geothermal heat pumps are on
average 3.75 to 5.8 times more cost effective than the high efficiency
gas or electric furnaces on the market today.
Geothermal
systems provide numerous benefits not available with traditional
heating and cooling systems:
Eliminates natural gas heating costs, as geothermal systems
require only a minimal amount of electricity to operate the
heat pump all year round.
Virtually eliminates hot spots in the winter
and cold spots during the summer, through consistent,
comfortable, and reliable heat AND cooling distribution.
Safest system available. No combustible fuels with the
potential for household fires, no carbon monoxide concerns,
and no green- house gas emissions.
Minimal
maintenance costs. Geo-energy systems only require periodic
air filter cleaning or changing and will typically outlast
traditional furnaces.
No unsightly and noisy outdoor air-conditioning systems.
Ground-source
heat pumps require very little maintenance or attention, compared
to the normal furnace/air conditioning systems. Not being exposed
to the elements, dirt, leaves or vandalism, and with less moving
parts, makes them highly dependable. The underground components,
when properly installed, are virtually worry free.
A
properly installed system offers the highest indoor air quality
available today. A study by the EPA found that high efficiency
ground-source systems are on average 48% more efficient than the
best gas furnace, and more than 75% more efficient than an oil
furnace.
The best system will outperform the best gas heat pumps by an
average of 36% in the heating mode, and 43% in the cooling mode.
Geothermal
units can be used in conjunction with existing cooling towers
in warmer climates.
