Customized Geothermal Loop Configurations

Vertical Closed-Loop Systems

High-density vertical boreholes (80m to 150m deep) with U-bend HDPE piping. Ideal for commercial office buildings, hospitals, and urban sites where surface land footprint is limited.

Horizontal Closed-Loop Systems

Shallow horizontal trenches (1.5m to 2.5m deep) with coiled or straight pipe configurations. Extremely cost-effective for large campus sites, agricultural facilities, and suburban developments.

Open-Loop Groundwater Systems

Extracts water directly from an aquifer well, passes it through an isolation heat exchanger, and reinjects it into a discharge well. Offers high efficiency for sites with abundant water tables.

Surface Water (Pond/Lake) Loops

Submerged closed-loop piping modules placed at the bottom of a nearby lake, pond, or water reservoir. Delivers low installation costs and exceptional thermal heat rejection.

Geothermal Performance

Why Choose Geothermal Energy Systems?

Heating COP up to 9 and Cooling EER up to 7

Geothermal heat pumps deliver 4.5 to 5.5 units of thermal cooling/heating for every 1 unit of electricity, outperforming conventional air-cooled systems by up to 50%.

Most Suitable For NET ZERO energy Buildings

Eliminates noisy roof-top condensers, cooling tower chemical treatment, and evaporative water consumption, preserving roof real estate for solar PV panels.

Decarbonization & ESG Goals

Directly reduces building Scope 1 and Scope 2 carbon emissions, helping real estate portfolios achieve Net Zero Carbon and ESG compliance.

50+ Year Underground Lifespan

High-density polyethylene (HDPE) ground loops are warrantied for decades with virtually zero maintenance, providing generational infrastructure value.
