Geoexchange: the other ‘geothermal’, by Yale Carden - Eco-Business

Published June 03, 2026

Geoexchange: The Alternative Geothermal Solution

Geoexchange systems, often referred to as geothermal heat pumps, are increasingly recognized as a viable alternative to traditional geothermal energy sources. This technology utilizes the earth's stable underground temperature to provide heating and cooling for buildings, making it a sustainable and efficient energy solution. Unlike conventional geothermal energy, which taps into hot water or steam from deep underground, geoexchange systems rely on the relatively constant temperature of the ground just below the surface, typically ranging from 10 to 20 degrees Celsius.

The principle behind geoexchange systems is straightforward. A series of pipes, known as ground loops, are installed either horizontally or vertically in the ground. These loops circulate a fluid—usually a mixture of water and antifreeze—which absorbs heat from the ground during the winter and releases heat back into the ground during the summer. This process allows buildings to maintain a comfortable indoor temperature year-round with significantly lower energy costs compared to traditional heating and cooling systems.

Cost-Effectiveness and Energy Efficiency

One of the most compelling advantages of geoexchange systems is their cost-effectiveness.
