Go Green, Save Green with a Geothermal Heat Pump

Geothermal heat pumps represent some of the best green technology available on the market today. These HVAC systems are eco-friendly and use little energy. Instead of putting a huge drain on the power grid, geothermal pumps rely heavily on the free energy offered up by Mother Nature. Every day, the solar energy from the sun is stored in the earth’s ground and bodies of water. Geothermal pumps capitalize on this free energy and put it to use heating and cooling indoor environments. With geothermal systems, consumers can reduce energy consumption and leave less of a carbon footprint along with saving up to 50 percent on energy bills.

How Geothermal Pumps Work

Geothermal systems consist of a heat exchanger, air delivery system and a heat pump. Through a network of buried pipes in the ground or water, the geothermal heat pump removes heat from the ground and pumps it into the home during the wintertime. In the summertime, the process is reversed, and the pump removes warm air from the home and deposits it into the ground. These systems can also be used to provide hot water. Often, a closed-loop system is used for residential applications.

Installation Considerations

Geology, hydrology and land availability all play a role in determining whether or not a geothermal pump is appropriate. Contractors evaluate the composition of the rock and soil for heat transfer. Typically, properties with good heat transfer require less piping. The amount of soil also determines system design. With soil that is too shallow, vertical ground loops may be installed instead of horizontal ones.

nLandscaping, amount of land and the location of underground utilities will also play a role in a system’s design. Generally, vertical installations are used with existing buildings due to minimal disturbance to the landscape, and horizontal ground loops are used with new construction.

nKeep in mind that installing a geothermal system just isn’t a do-it-yourself job. To make sure your system is properly sized and installed, it’s imperative to work with a licensed contractor. Your contractor can help you decide if a geothermal system is right for your home or if another energy-saving option, such as a heat pump or ductless system makes more sense.
