All other geothermal heating and cooling providers in Australia use water-based earth loops to power their systems. The disadvantage of this is that water loops require expensive excavations since they need to be dug deep down into the ground.
EarthLinked® is the only system in Australia to use a refrigerant in their earth loops, enabling Energycore to offer both lower installation costs (due to less excavation costs) as well as a more efficient use of the earth heat.
