How Geothermal Works
A major source of energy is right under your feet
Your own backyard has the potential to be your source of heating and cooling comfort. Now you can get safe, reliable, energy efficient heating and cooling from one piece of equipment. Geothermal energy represents the leading edge of heating and cooling technology. It moves heat energy to and from the earth to heat and cool your indoor environment. And compared to ordinary systems, geothermal technology can save you 30% to 60% on your monthly energy bills. Geothermal is the safest, cleanest, most reliable space conditioning system you can buy.
Geothermal energy is an unlimited resource. The lot surrounding a suburban home or other building contains a vast reservoir of low-temperature thermal energy, typically 10 times that required over an entire heating season. This resource is constantly resupplied by the sun, the surrounding earth, and heat rejected while cooling during the summer. The universal definition of geothermal is “…pertaining to the heat of the earth.” By using the earth to provide up to 50% of a building’s total heating and cooling needs, GHP systems are truly geothermal energy made practical.
Geothermal Vertical Loop
A vertical loop is an ideal choice for a geothermal heat pump when the available land surface is limited. Well drilling equipment is used to bore small-diameter holes from 100 to 400 feet deep.
Geothermal Horizontal Loop
Horizontal loops are typically used when adequate land surface is available. Depending on the geothermal system needs and space available, pipes are placed in trenches that range in length from 100 to 400 feet.
Open loops are also referred to as Well Water Loops, and in ideal conditions, an open loop installation can be the most economical type of geothermal system. An open loop configuration uses groundwater from a well as a direct energy source.
Geothermal Pond Loop
Also called a Lake Loop, this method is a very economical way to install when a large body of water is available for use near the geothermal heating and air conditioning system. Coils of pipe are placed on the bottom of the pond or lake to capture and exchange the geothermal energy.
Four Times The Efficiency: A geothermal system uses the Earth’s thermal properties in conjunction with electricity to provide unprecedented efficiency. For every unit of electricity the system uses, it provides four units of heating energy, giving a geothermal system a 400% efficiency rating on average. These numbers can translate into real savings on your utility bills year-round.
