Geothermal Heat Pumps

What is a geothermal heat pump? Also known as a ground source heat pump (GSHP), this type of heating and cooling system uses the earth's constant temperature as a heat source and heat sink. It transfers heat to or from the ground, depending on whether the building needs heating or cooling.

Geothermal heat pumps operate similarly to air source heat pumps, with the key difference being that they use the ground to transfer heat, rather than relying on outside air. These systems circulate water or a water-glycol mixture through a ground loop (also called a ground heat exchanger). In the winter, the geothermal system absorbs heat from the earth and transfers it into the building to provide heated air. In the summer, the process reverses, transferring excess heat from the building into the ground to help cool the space.

Geothermal heat pump technology is highly efficient because the earth maintains a consistent temperature year-round, unlike fluctuating air temperatures above ground. This consistency makes ground source heat pumps ideal for reliable heating and cooling.

A geothermal heat pump system offers a dependable solution for providing heated or cooled air while delivering energy savings over time.

AAON geothermal heat pumps provide the ultimate in performance, optimization, and long-term value. With industry-leading quality, you can expect superior energy savings, accessible maintenance, and exceptional reliability. 

Key Features and Specifications: 

• Available in Indoor Self-Contained Units, Outdoor Rooftop Units, or Split Systems Designs. Rooftop Units are available in 2-70 tons, while Self-Contained Units are available in 3-70 tons.

• AAON heat pumps feature double wall rigid polyurethane foam panel construction, direct drive backward curved plenum fans, economizers, energy recovery, and options for electric, gas, steam, and hot water auxiliary heating.

• Many of the same options found in air cooled heat pumps are available, such as energy recovery, hot gas reheat, and auxiliary supplemental heat. These configuration options are also available in the SA, SB, and M2 products.

When selecting geothermal heat pumps or ground source heat pumps, several factors should be considered:

• Site Suitability: Geothermal heat pumps are ideal for large facilities that either have a centralized chiller/boiler system or have invested in a geothermal field. Typical institutions include schools, college campuses, large corporate campuses, or high-rise buildings (office or residential) where rooftop space is not proportional to the high occupant density.

• System Size: The heat pump and ground loop system must be properly sized to meet the building's heating and cooling demands. Oversizing or under-sizing can lead to decreased efficiency and increased costs.

• Available Incentives: In some regions, government incentives or rebates may be available for installing geothermal heat pump systems. Buyers should investigate these incentives and factor them into the overall cost analysis.

We don't just claim to be the best. We prove it to ourselves and the industry through thorough testing, robust quality control measures, and certifications.

• Tested to stand the test of time. With our very own state-of-the-art research and development lab, we can conduct research, product development, and rigorous testing of new and existing products. Our R&D facility allows us to test to AHRI standards and even under more extreme conditions than certification testing standards or what our competitors can perform.

• Committed to quality. Our dedication to our customers, compliance with regulatory requirements, and commitment to stakeholders are the greatest incentives for our quality goals. Every product undergoes thorough inspection, testing, and final review.

• Certified for excellence. Many of our products meet certification standards of the governing body for the HVAC industry, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).

AAON units are designed with features that make it easier to save time and money.

• Designed with access in mind. AAON units are designed with full length hinge doors instead of removable panels with sheet metal screws that can be easily lost or stripped over time.

• Proactive troubleshooting. Since troubleshooting wiring is often the first step in identifying issues, AAON provides full color, complete wiring diagrams laminated inside each unit. No more black and white diagrams that prevent ease of diagnosing the problem.

• We're about getting the job done. AAON provides every technician comprehensive support with a dedicated Service & Tech Support team. 

We’re here to help protect your investment. Get peace of mind with warranty programs that ensure your unit is built to last. 

• The Limited Warranty is effective for 12 months from the date of original installation, or 18 months from the date of original shipment from the factory, whichever occurs first.

• Compressors are covered for 12 months from the date of shipment from the factory.

• Optional 5-Year Extended Limited Warranties are available for purchase.
