Everything You Ever Wanted To Know About Geothermal Heat Pump Systems


Geothermal heat pumps really are a great way to heat and cool your home.

The popularity of alternative energy solutions has given rise to the increase of homeowners searching for alternative energy sources in their homes. Geothermal heat pumps use alternative energy to provide comfort in your home. Interested in learning more? Here is a handy guide that will give you everything you could possibly need to know about the excellent benefits associated with geothermal heat pumps and how they work.

What Exactly Is Geothermal?

Geothermal energy is an alternative energy source that uses the earth’s surface to generate heat or, conversely, cold air. It is one of the best ways to get clean, renewable energy. Most geothermal systems use a series of pipes underground that help grabs the heat generated by the Earth’s core and use that energy to heat or cool your home.

Environmentally Friendly

Because geothermal heat pumps use the Earth’s core to heat and cool your home, they are considered a green energy source. With lower carbon dioxide emissions, geothermal systems contribute less pollution than traditional heating and cooling systems. With a smaller carbon footprint, geothermal heat pumps are a fantastic way to heat and cool your home when compared to conventional energy methods.

Types Of Geothermal Heat Pump Systems

There are four basic types of ground loop systems. Depending on the climate you live in, soil conditions, available land, and installation costs, different kinds of loop systems would be more beneficial than others.


  • Closed-Loop: Most closed-loop systems circulate an antifreeze solution through a closed loop. This loop is typically made of plastic tubing. The tubing is usually buried in the ground or submerged in water. A heat exchanger subsequently transfers heat from the refrigerant in the heat pump to the antifreeze solution in the closed loop.
  • Horizontal: With horizontal installation, it is typically the most affordable option for residential structures where sufficient land is available. In fact, these systems require trenches that are at least four feet deep. The most common layouts involve either using two pipes buried at different levels or two pipes buried side-by-side.
  • Vertical: Large commercial structures will typically require a vertical system. Vertical loops are also used in places where the soil is too shallow for trenching. With a vertical loop, holes are drilled about twenty feet (20 ft.) apart and one-hundred (100) to four-hundred (400) feet deep. Then, two pipes go into these holes connected by a u-bend which ultimately forms the loop.
  • Open-Loop: With an open-loop system, well or surface body water is used as the heat exchange fluid. Once this water has circulated through the ground loop system, the water then returns to the ground via the well. This option is practical only in places where there is a sufficient amount of relatively clean water and with local codes allowing a ground loop system to be installed.
