Geothermal Heating & Cooling Systems
High Oil Prices Breaking Your Budget?
We can help! An environmentally-friendly geothermal heating system may be the answer to your high heating costs. According to the U.S. Environmental Protection Agency (EPA), geothermal systems are "the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available today." These extremely high levels of efficiency are possible because a geothermal heat pump only uses electricity to move heat, not produce it.
 
How Do Geothermal Systems Work?
Water is circulated through the earth and acts as a heat transfer medium. In the winter, heat is transferred from the earth to your home, and in the summer, heat is transferred from your home to the earth.
 
Are there different types of geothermal systems?
Yes, there are essentially two types of geothermal systems used in New Hampshire, open-loop and closed-loop. Our trained professional can work with you to determine the best system for your needs.
  • Open-loop geothermal system includes a groundwater well (or wells), a water well pump, piping and a compressor [heat pump] installed in the structure. In this type of system, groundwater is used as the heat transfer fluid and is pumped out of the well, and circulated through the structure's heat pump where heat is extracted from or injected into the water. Then the heated/cooled water is re-injected into the same groundwater well from which it was withdrawn or a separate well dedicated to re-injection.
  • Closed-loop geothermal system. In these systems, an antifreeze solution is circulated through a continuous loop of plastic or copper pipe, which is installed in either a drilled well, horizontal trench or the bottom of a surface water body. Similar to the open-loop system, heat is either injected into or extracted from the antifreeze by the heat pump; after which, the fluid is re-circulated back into the loop of pipe installed in the ground.
