High Energy Savings with a Low Initial Investment
Use Earth’s energy to heat and cool your home.
Geothermal heat pump systems are an incredibly quiet and
efficient way to heat and cool your home. Because you are using
the natural energy from the Earth, you can reduce your monthly
utility bills by as much as 70 percent. Best of all, geothermal
systems can be installed in any sized home in almost any location.
Save energy. Save money.
Typical central cooling systems work by exchanging heat with the
air. Because ambient air temperatures can vary greatly, how hard
the system has to work varies as well. When temperatures outside
are very hot, for instance, it is harder to disperse heat into already
hot air.
A geothermal heat pump, on the other hand, exchanges heat with
the ground. While the air outside will vary in temperature, the
ground stays a fairly consistent 55°-70°F year-round. That means
a geothermal system doesn’t have to work nearly as hard to
disperse heat as a traditional split-system air conditioner or heat
pump, which is how it operates so efficiently.
In the winter, geothermal heat pumps simply move the heat from
the ground to your home. Unlike a gas furnace, geothermal heat
pumps don’t burn a fuel source to create heat.
