Geothermal Question: How Does Geothermal Work?

Geothermal literally means “earth heat.” It is a home heating system that draws on the  consistent temperature of the ground beneath the surface. Recent developments in HVAC technology have brought this eco-friendly and renewable energy source into the home as a viable alternative to fuel-based systems. Most geothermal heat pump systems are highly-efficient, Energy-Star rated, and qualify for Federal Tax Credit. There are several stages in assessing and planning for the installation and operation of a geothermal system, but the first step is understanding how geothermal works and what makes it different from other systems. For more detailed information and to see if geothermal is right for heating your home, please call Raleigh Heating & Air, serving Raleigh and the surrounding areas.

The key to geothermal energy Is the fact that 5-10 feet under the ground, the earth remains at around a constant 55 degrees.  Underground piping, known as the “loop system” is installed, and water or a water refrigerant mixture is circulated through these pipes, absorbing heat. The heat pump then transfers the heat to the air which is circulated by the ducts in your home. During the summer, the refrigerant absorbs the heat in your home and it is dispersed in the ground loops, keeping your home cool and comfortable.

Geothermal energy is a highly-efficient “green” alternative to conventional fuel sources. While many will be attracted to the eco-friendly aspect of geothermal systems, others may be more pleased to eliminate fuel costs.  The geothermal system is also versatile: in most cases, it can also be configured to heat your hot water.
