APGE Piles® using the latest advances in geothermal technology are an ideal choice for heating and cooling virtually every size of commercial building. A loop system of pipes is installed within the APGE Piles® during construction. A water based solution is circulated through the closed loop system during operation. While heating the structure, the solution absorbs heat from the soil and transports it to the geothermal heat pumps in the building where it is compressed (pumped) to a high temperature and distributed through the building. During cooling the process is reversed using the same equipment by extracting heat from the building and replacing it with cool, dehumidified air. In addition to lower operating costs and higher efficiency, geothermal systems are safe, clean, and maintenance free. Because they don’t burn fossil fuels there are no flames, fumes or direct carbon emissions from these systems.
