GeoExchange BC and this web site are dedicated to the education, promotion and responsible design and installation of low-temperature ground source (geoexchange) energy systems.

Geoexchange systems, also known as "geothermal", "geothermal heat pump" or "ground source" energy systems, are recognized as the most energy efficient means of heating and cooling a building and providing domestic hot water. 

We favour using the term geoexchange for low-temperature earth energy (commonly used for building heating and cooling with a heat pump), to distinguish it from medium and high-temperature geothermal technology (commonly intended for power generation or direct heating applications).
