Geothermal
Geothermal systems harness the abundant heat stored within the earth, making them an efficient and sustainable choice for commercial properties. Whether you’re looking to heat or cool your building, geothermal technology offers a cost-effective solution. Let’s delve into the workings of commercial geothermal systems and explore the installation options available.

How Does Geothermal Work?
The Science Behind Geothermal Systems
Geothermal heat pumps (GHPs) take advantage of the Earth’s consistent underground temperature, around 50 degrees Fahrenheit, regardless of the season or local climate conditions. This remarkable heat source enables GHPs to efficiently regulate indoor temperatures throughout the year.
Understanding Geothermal Heat Transfer
To provide both heating and cooling, GHPs utilize a closed-loop system with underground heat exchanger pipes. The most common installation method for commercial properties involves horizontal loops buried at the appropriate depth using trenching. These high-density polyethylene (PE) pipes circulate an anti-freeze solution, which extracts heat from the ground during colder months and transfers it to the GHP unit inside the building. The warmth is then distributed via forced air throughout the entire commercial space.
Cooling Effect in Warm Weather
During warmer months, the geothermal system reverses its operation, acting as an air conditioner. The GHP unit extracts heat from the building’s interior and transfers it back into the Earth through the same loop system. This process provides efficient and eco-friendly cooling, ensuring a comfortable indoor environment for your commercial establishment.
Tailored Installation Options for Commercial Properties
Horizontal System: The most commonly used installation method, a horizontal system involves burying closed-loop PE pipes in a trench. This option is suitable for properties with ample space and provides excellent energy transfer capabilities.
Vertical System: When space is limited, a vertical closed-pipe system proves advantageous. By drilling holes to a depth of approximately 150-300 feet, the system maximizes the use of vertical space while effectively utilizing the Earth’s heat.

- Water-Based System: For commercial properties with access to a deep-water pond or lake, a water-based system offers an alternative installation approach. By utilizing a closed loop system that taps into the constant temperature of the water bed, this method eliminates the need for trenching or drilling, reducing installation costs.
Conclusion
Commercial geothermal systems provide a sustainable and energy-efficient solution for heating and cooling commercial properties. By leveraging the Earth’s natural heat, these systems contribute to cost savings and environmental sustainability.
