Understanding How a Geothermal Heat Pump Works

For an effective and eco-friendly way to heat your home, consider installing a geothermal heating system, which involves a heat pump that taps into the earth’s heat to keep your home comfortable during cooler months. Our geothermal solutions can save you substantial amounts of money on your utility bills.

Understanding Geothermal Heat Pump

Since geothermal energy is a renewable resource, this method of heating also goes a long way in conserving resources. Learn more about geothermal heat systems here.

What Is a Geothermal Heat Pump?

A ground source heat pump is a geothermal heating system that takes advantage of the naturally occurring difference between subsurface soil temperature and above-ground air temperature. A geoexchange or ground source system consists of a heat pump connected to a series of buried pipes. These pipes can be installed in vertical boreholes that go several hundred feet below ground or in horizontal trenches just below the ground surface.

A heat pump can move heat from the ground to the building if the ground temperature is warmer than the ambient air temperature. The system can also work in reverse and move heat from the ambient air into the ground, cooling your home. Even though ground source heat pumps require a small amount of energy to drive the process, there is still a net energy benefit. For every unit of electricity used to operate the heat pump, the system can deliver as much as five times the energy from the ground.

How Does a Geothermal Heat Pump Work?

The way a geothermal heat pump works is simple, though seemingly complex on paper. First, the above-ground heat pump circulates water or another fluid through a series of pipes in the ground. As the water moves through the ground loop, it will then absorb heat from the warmer rock, soil, or groundwater around it. The heated water returns to the building where it can be used for heating.

This heating system uses a heat exchanger to transfer heat into the building’s air handling, distribution, and ventilation system. Once the fluid transfers heat, it then returns to a lower temperature before restarting the whole process again.

What Are the Benefits of a Geothermal Heat Pump?

This geothermal heating system is relatively cost-effective. The biggest investment would be the underground installation of ground loops around the home. A ground source heat pump can support the space heating needs of any home in almost any part of the country. You can also use this system for domestic hot water applications. This system is also scalable by increasing the capacity of the piping loops.

For homes with a large amount of yard space, we recommend a horizontal loop installation. If there is limited space available, then we can use a drilling rig to dig 150 feet down and install a vertical loop system. If conditions call for it, then we can also install a well water loop. If the home is near a pond, then we can dig trenches from the home to the body of water. We will install coils beneath the water and use this to heat and cool your home.
