What is GeoExchange?

GeoExchange is the industry's term used to describe an alternative to traditional oil- gas- or coal-fired heating, ventilation and air conditioning (HVAC) systems. Geoexchange systems have also been referred to as earth energy systems, or geothermal heat pump systems.

The idea is to take advantage of the ground's heating and cooling properties (the same properties that make any basement cooler in the summer and warmer in the winter) to heat or cool entire buildings. This heat 'exchange' between the ground and the building is accomplished by using standard pump and compressor technology.

The advantages of geoexchange technology include:

  • Geoexchange technology can save the developer or consumer up to 70% on their current heating bills, because it transfers existing heat without combustion,
  • Geoexchange often pays for itself in less time than a traditional HVAC system, depending on current building heat/cool use, soil types, size of installation, and other factors.
  • Geoexchange qualifies as a renewable energy - a typical two bedroom house-sized installation is equivalent to taking two cars off the road or planting one acre of trees.
  • Geoexchange systems involve no combustion, so they are cleaner and safer to handle than either oil or gas.
  • Geoexchange takes up much less space than traditional HVAC systems, they are particularly suitable for situations where space is at a premium and/or aesthetics matter.
