CLOSED LOOP GEOTHERMAL WELLS & INSTALLATION


A Closed Loop System utilizes a water or antifreeze solution circulated through plastic piping buried beneath the earth’s surface. During the cold winter months the fluid utilizes the heat from the earth and carries it through the system and brings it into the building, in the summer this reverses by pulling the heat from the building carrying it through the system and placing it back into the ground. The added benefit of this process is free hot water in warmer months and significant savings in winter months.

Closed loop wells are typically utilized in areas that ledge is nearby and/or large amount of square footage is not available. Large benefits of closed loop is that the maintenance is minimal and life expectancy is 30+ years. If there is a need for water at the location for irrigation use or domestic supply an open loop system may be considered as an option as well.
