Sub-Surface Geothermal provides geothermal drilling and installation services. They are specialized in providing geothermal loop installation services. The company is a certified installer for fusion joints and also a certified geothermal installer for International Ground Source Heat Pump Association. The company is equipped to drill deeper vertical loop fields with a depth of more than 500 feet. Sub-Surface Geothermal has drilled rigs at Lake Forest, Lake Bluff, Kenilworth, Winnetka, Glencoe, Hawthorn Woods, and Libertyville in Illinois.
Sub-Surface Geothermal installs closed loop systems. The geothermal closed loop systems can be installed in three methods, namely, horizontal, vertical, and pond or lake. The company chooses the appropriate type based on the availability of land, and the soil and rock present at the site. The closed loop systems help to circulate propylene glycol and water through polyethylene pipes.
The polyethylene pipes are buried horizontally or vertically in the ground. The fluid present in the closed loop system captures heat from the ground and sends into the building through the ground source heat pump. During summer, the heat from the building is carried through the system to the ground. This heat can be utilized to produce hot water during summer. The heat also helps to save cost of heating water during winter.
