MRCOOL Open Loop Installation Kit 2-5 Ton GCIK-OL2-5-00

The MRCOOL Open Loop Installation Kit 2‑5 Ton (model GCIK‑OL2‑5‑00) is a complete accessory kit designed to support open loop geothermal HVAC systems ranging from 2 to 5 tons. This kit provides the essential components needed to connect a geothermal heat pump to a groundwater source — such as a well or lake — allowing your system to efficiently use natural water heat exchange for year‑round heating and cooling performance.

Engineered specifically for open loop geothermal installations, the kit is compatible with MRCOOL GeoCool Inverter Series geothermal heat pumps and helps streamline the setup process. It includes the necessary fittings and parts to facilitate a reliable water‑source connection, making it suitable for both new installations and retrofit projects that convert traditional HVAC systems to geothermal.

Built with durability in mind, the components are made from quality materials to resist corrosion and stand up to long‑term use with water‑based systems. This ensures that your geothermal system can operate consistently and dependably with minimal maintenance once properly installed.

Ideal for homeowners or professionals working on groundwater geothermal installations, the MRCOOL Open Loop Installation Kit 2‑5 Ton supports efficient heat pump performance and simplifies the process of establishing an open loop ground‑source circuit that enhances both heating and cooling efficiency throughout the year.

Frequently-Asked Questions

Is this kit compatible with other geothermal brands?
While it’s designed for MRCOOL systems, compatibility with other units depends on system specs—consult with your installer for confirmation.

What’s the difference between open and closed loop kits?
Open loop systems use groundwater directly, while closed loop systems circulate a refrigerant or antifreeze through buried pipes.

Can this be installed DIY?
Professional installation is recommended due to the complexity of geothermal systems and water source connections.
