Geothermal Heat Pump (GHP)

Proclaimed by some as the ultimate "green" way to provide heating and cooling for your home, this renewable energy source is definitely worth consideration. Ask your local geothermal contractor about current tax incentives, as the growing popularity will continue to make it a more affordable solution for not only lowering utility bills, but protecting the world we live in.
How Does A GHP Work?
A geothermal heat pump (GHP) is the equipment used for heating and cooling. Similar to an all electric or "air source" heat pump it is able to provide both heating and cooling for your home, however a geothermal heat pump is able to heat better than an all electric or "air source" version can.

To understand how it works, you need to understand that there is a large "loop" that makes up the heating and cooling system. Even with a traditional A/C installation this loops exists, but is referred to as an outdoor coil and indoor coil. With normal home air conditioning, the air conditioner or heat pump contains the outdoor coil, and a fan coil or air handler contains the indoor coil. Refrigerant is chilled by the air conditioner, and pumped inside to the indoor coil where warm air from your home is forced through to cool it.

With a GHP installation, the outdoor coil is now called an earth loop. It is made of durable, high-density polyethylene pipe and contains a water based fluid. In the cooling season, heat energy is dissipated into the ground from the earth loop. The now chilled fluid is pumped back inside to the indoor coil where warm air from your home is forced through. In the heating season, this process is reversed. Heat energy from the constant thermal temperature of the ground is used to heat the fluid. The heated fluid is pumped inside to the indoor coil where cool air from your home is forced through to provide heat.

Call us at (904) 819-0234 to have this explained in more detail, but there are four primary types of earth loop installation methods when installing a new GHP solution. If you click on an image below, you can view a larger version to better explain the concept.
Geothermal Horizontal Loop
Horizontal Loop
When you own enough land around your home, horizontal loops can be the ideal earth loop system to install. Depending on the exact system needs and space available around your home, pipes are placed in trenches that range in length from 100 to 400 feet.
Geothermal Horizontal Loop
Vertical Loop
When not much yard or land is available, a vertical earth loop can be the way to go for your geothermal heat pump installation. Small diameter holes are bored into the ground using well drilling equipment. The polyethylene piping is then installed into these holes that range from 100-400 feet deep!
Geothermal Horizontal Loop
Open (Well Water) Loop
In ideal conditions (a little rare), an open-loop can be the lowest cost type of geothermal installation for your home. Open loops use groundwater from a well as a direct energy source.
Geothermal Horizontal Loop
Pond/Lake Loop
Pond/Lake loops are extremely economical to install when a body of water is nearby. Coils of piping are placed on the bottom of the pond or lake to capture the geothermal energy and either dissipate or obtain heat energy.
