By working with nature to utilise the stored RENEWABLE thermal energy provided we can offer solutions with the following benefits:

  • Reduced Overall Power Usage
  • Reduced Peak Power Usage
  • Integration with onsite Solar PV
  • Flexible Applications including Ducted heating and cooling, heated and chilled water and pool heating
  • Experience True Comfort
  • No need to burn fossil fuels onsite
  • Recover Waste Heat

Where can Geoexchange Systems be used?

 Geoexchange heat pumps are appropriate for new construction as well as retrofits of older buildings.  Their flexible design requirements make them a good choice for schools, high-rises, government buildings, apartments, and restaurants and almost any commercial property. Lower operating and maintenance costs, durability, and energy conservation make Geoexchange heat pumps the smart choice for commercial applications.

How Does A Commercial Geoexchange System Work?​

 A few meters beneath the surface, the earth’s temperature remains fairly constant. Geoexchange takes advantage of this constant temperature to provide extremely efficient heating and cooling.

In winter, a water solution circulating through pipes buried in the ground absorbs heat from the earth and carries it into the building. Inside the building a heat pump is utilised to concentrate the earth’s thermal energy and then to transfer it to the required application.

In the summer, the process is reversed. The heat that is extracted from the air inside or the water in the chilled system is transferred through the heat pump to the ground loop piping. The water solution in the ground loop then carries the excess heat back to the earth.

St Peter's College Adelaide Geoexchange System

In 2016, St Peter’s College in Adelaide became the first school in South Australia to use a Geoexchange system to heat their indoor pool and provide space conditioning to the pool enclosure. We are proud to have been involved in the project undertaking the installation of the plant and equipment on behalf of Geoexchange Australia.  

At the school ground temperatures of 18 Degrees Celsius are accessed through the installation of a Ground Heat Exchanger (GHX) beneath the adjacent sports oval. This consists of 45 boreholes drilled to a depth of 70 metres each. The water circulated through the polyethylene pipe within this GHX extract heat from the ground and deliver it to a series of Ground Source Heat Pumps (GSHPs) that are located in the main plant room. Two of the GSHPs transfer this heat from the GHX into the pool water while six GSHPs supply the pool hall with space heating and/or cooling.

Ducted Heating and Cooling

 With the choice of packaged water to air geoexchange heat pumps or chilled water fan coil units a Geoexchange solution is flexible to fit into any project. The added bonus of a geoexchange system is where conventional systems reject heat when cooling to the air a geoexchange system moves that heat to the ground for future use just like using a battery. Also with the option to have units on the same loop system in simultaneously heating and cooling you can move heat from one area to another eg. If you are cooling one space you can move the heat to a pool to heat it.

Pool and Spa Heating

 By using Water to Water Geoexchange heat pumps to heat your pool and spa you can can expect to see a reduction in the overall running cost of your centre. The pool heating systems can be integrated into the pool halls space conditioning to recover waste heat and also has the option of utilising heat from other areas that are being cooled.

Geoexchange for Developments

 Growing in popularity overseas is the use of Geoexchange in developments as a district style system. This allows for the sharing of thermal energy between properties and reduces the amount of energy input required. By sharing the thermal energy within the development it cuts down on the amount of ground loop required.

The required loop field can be installed into the green/park areas around the development.

Heated and chilled water for Manufacturing

Adelaide Geoexchange Pride ourselves in being the leaders in Commercial Geoexchange for heated and chilled water in South Australia. In our research we have found that a number of manufacturing facilities in rural and regional areas are still using LPG to heat water and outdated and old technology for chilling water. Did you know with geoexchange we can remove heat from a space or water and transfer that heat to another area of water?

Geoexchange For Farms

Adelaide Geoexchange Pride ourselves in being the leaders in Commercial Geoexchange solutions for Farms in South Australia. Is your farm a large user of LPG for processes or heating of pens or enclosures etc. We can design and provide a geoexchange system to help reduce or remove your reliance on LPG.

Geoexchange For Wineries

Adelaide Geoexchange Pride ourselves in being the leaders in being able to provide a number of solutions to Wineries in South Australia. From heating and cooling cellar doors to the production of large amounts of hot water we have solutions to help.

Ice Rinks

 We can provide Ice production with the added bonus of heat capture for hot water, bench warming and ice edge warming.

Geoexchange + Solar PV

If you are producing a large amount of onsite energy with solar PV it is best put to use with efficient electrically driven Geoexchange systems.
