Geothermal Heat Pumps

Underneath your lawn there is a vast array of thermal energy that is the result of the sun hitting the Earth's surface. This thermal energy remains at a fairly constant temperature, whether we are in the middle of a chilly North Carolina winter, or a blazing hot summer.

To understand how a geothermal heat pump works, you must first understand one basic concept about heating and air conditioning: keeping your home cool or warm is about doing one thing, and that is moving heat energy. In the summer, your air conditioner doesn't blow cold air into your home. It pumps chilled refrigerant inside to an metal coil. Warm air from your home passes through the coil, and heat energy is removed, and absorbed into the refrigerant. The now heated refrigerant is sent back outside to the air conditioner, which dispenses the heat energy into the outside air.

A geothermal heat pump essentially does the same thing, but it uses large "earth loops" installed into the ground or adjacent water to perform the heat energy exchange. This is much more efficient than using the outside air, and thus greatly reduces utility bills!

Geothermal Pond Loop

Pond Loop

If you have an adjacent (and controlled) pond or lake next to your home, a pond loop can provide some of the highest geothermal efficiency available! Sealed piping is submerged under the surface.
Geothermal Well Water Loop

Well Water Loop

If you have plentiful ground water beneath your home, a well water setup can be directly used as opposed to the sealed piping loop.
Geothermal Horizontal Loop System

Horizontal Loop

If your Brevard property has adequate land area, a horizontal earth loop installation can be used. A trench typically 3-6 feet deep is dug, and the sealed piping is installed in the trench.
Geothermal Vertical Loop

Vertical Loop

If yard space is limited, and ground water and/or adjacent pond water is not available, a vertical loop is used. Small holes are dug up to 400 feet deep using a well-drilling rig. The sealed piping is installed into these holes.
