Horizontal loops are suitable for properties with ample land, while vertical loops are ideal for smaller lots or when minimizing ground disturbance is a priority.
System Sizing: The heat pump and loop field are meticulously sized to match your home’s calculated energy load. Precise sizing ensures the system operates efficiently, avoiding the inefficiencies and higher operating costs associated with improperly sized units.
Integration Planning: The design considers how the geothermal system will seamlessly integrate with your home's existing air distribution system or, if necessary, outlines modifications or new ductwork installations for optimal airflow.
Hot Water Integration: Options for integrating a desuperheater to provide supplemental hot water, further enhancing energy savings, are also incorporated into the design.

Loop Installation Considerations: Beneath Your St. Matthews Property

The ground loop is the heart of any geothermal system, circulating a heat-exchange fluid to transfer thermal energy with the earth. The method of loop installation is critical and chosen based on your property’s characteristics and the system design:

Horizontal Loops: If your St. Matthews property has sufficient available land, horizontal loops involve excavating trenches typically 4 to 6 feet deep where multiple pipes are laid in parallel. This method can be cost-effective for larger lots.
Vertical Loops: For properties with limited yard space or when preserving the landscape is a priority, vertical loops are often preferred. This involves drilling several boreholes, usually 150 to 400 feet deep, into which U-shaped pipes are inserted. This method minimizes surface disruption.
Closed-Loop Systems: The most common and reliable method, closed-loop systems circulate a sealed, non-toxic antifreeze solution through the pipes, offering a maintenance-friendly and environmentally secure option.
Material Quality: High-density polyethylene (HDPE) piping is used for its durability, resistance to corrosion, and long lifespan, ensuring the integrity of the underground heat exchanger for decades.

Selecting the Right Geothermal Heat Pump

Choosing the appropriate geothermal heat pump is integral to the system’s overall performance and efficiency. These units are specifically designed to interact with the ground loop and distribute conditioned air throughout your home. Key considerations include:
