Closed-Loop Systems
There are three ways to install a closed-loop geothermal heat pump system. Closed-loop systems can be installed horizontally, vertically or in a body of water such as a pond or lake. Deciding what type of installation design to choose depends on a variety of factors including land area, climate, ground conditions and cost of installation. Third party specialists install horizontal and vertical closed loop geothermal systems.

The most cost effective way to install a horizontal loop system is using the Slinky™ method. This method allows for the use of more pipe in a limited amount of land area, which can decrease installation costs.

geothermal vertical loop installation diagram A vertical loop installation is used when land area for the geothermal heat pump is restricted or when the ground conditions do not allow for a horizontal loop installation. Typically, holes for this type of installation are drilled between 100 feet and 400 feet into the ground.

geothermal pond loop installation diagram Pond or lake loop installations occur when there is a body of water located near your home that would be useful for installing a geothermal heat pump system. This option is cost effective because the installation process is not as complex as a horizontal or vertical loop system. Installation for this type of closed-loop system consists of running a pipe from the home to the nearby body of water. The coils, which are assembled on dry
land, are then placed at the bottom of the pond or lake.

Open Loop System

Replacement vs. New Construction

Whether you are looking to replace an existing heating and air conditioning system in your home or you are in need of a new system for a home you are building, a geothermal heat pump is an energy-efficient option for you. Geothermal heat pumps can be installed using a closed-loop system, which consists of a horizontal, vertical, or pond/lake installation, or an open-loop system, which utilizes well-water as a source of energy. Deciding what type of installation design to choose depends on a variety of factors including land area, climate, ground conditions and cost of installation.

On a retrofit, a geothermal heat pump can replace virtually any system because fossil fuels are not required for operation. Geothermal heat pump systems are safe to operate and, according to a study completed by the EPA, "the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available today."

Building a new home? Installing a geothermal heat pump system during new home construction is a cost-effective solution to lowering your energy costs. Because your home has not been built, the system and install can be customized to your specifications and the cost can be included in your monthly mortgage payment.

Installation Experience

Below is an overview of what you can usually expect with a geothermal installation.

  • Pre-Install Review: Prior to starting the installation, the team lead will review the job details and answer any questions to ensure we are meeting all of your expectations.
  • Installation Preparation: The team will prepare the work area for a clean and safe installation, by laying drop cloths and removing any potential safety obstacles. In the case of asbestos or hazardous materials, preparations may be completed prior to the installation day.
  • Turn Off the Power: Before removing the old equipment, the geothermal specialists will turn the electrical breakers off to the system(s).
  • Refrigerant Removal: For central air conditioner replacements, the refrigerant in the system will be recovered accordingly to state and EPA guidelines for proper disposal.
  • Equipment Removal: Once all safety precautions are satisfied, the installers will disconnect and remove the existing equipment.
  • Site Preparation: After the old equipment is removed, the site will be cleaned and prepared for installation.
  • Equipment Installation: The equipment will be set in place, connected to existing ductwork and wired accordingly. Emergency disconnect boxes will be installed at each unit and electrical fuses upgraded to ensure load capacity.
  • Equipment Pressurization: The system will be pressurized and tested to ensure proper operation and confirm no leaks in the lines.
  • Refrigerant Charging: Based on your system selection and application, your new geothermal system may or may not require new refrigeration lines. If new lines are required, after confirming the system maintains the appropriate pressure, the geothermal unit will be charged with environmentally-friendly refrigerant.
  • Thermostat Installation: The thermostat is now mounted and calibrated to ensure proper operation.
  • Accessory Installation: Any accessories, such as a GeoTank™ or AlpinePure™, will be installed and tested.
  • System Startup: The system is then started to ensure proper operation. The geothermal specialist will run the system for a period of time, confirming the appropriate compressor amp draws, checking the charge of the refrigerant and validating overall operation.
  • Installation is Complete: A successful startup signifies the completion of the installation. The team will then clean up the work area, removing any remnants of the installation and leave your home looking neat.
  • Post-Install Review: The lead installer will walk you through the installation, demonstrate how to operate your new geothermal system, thermostat and accessories, and answer any questions.
  • Final Paperwork: Once you are comfortable with operating your new system and after answering any questions, the lead installer will review all paperwork, warranty information, and discuss the financing or collect the final payment.
  • Installation Inspection: Scheduled at your convenience, the team lead will request a date so that an inspection can be scheduled with your local jurisdiction. The inspectors will review the work and confirm that everything meets local and state codes.
  • 6 Month Loop Pressure Test: Six months after your geothermal installation is complete, our preferred geothermal specialists will come out and perform a system check to ensure your new geothermal unit is operating at peak efficiency.

Your Installation Day

The installation of your new geothermal heat pump system is an exciting experience, especially when you have a professional team taking care of everything for you. Below are a few ways you can prepare for your installation day.

  • Remove any obstructions around the furnace(s) or air conditioner(s)
  • Close all air vents throughout the home (on the day of the installation)
  • Ensure all areas of your home are accessible
