Geothermal is Renewable Energy in a Natural Way
Geothermal systems are powered by renewable green energy in a natural way – by using the consistent temperatures of the ground underneath and surrounding your home for winter heating and summer cooling. Geothermal heat pumps use the constant temperature of the earth as the exchange medium instead of the outside air temperature, according to Energy.gov.
What is a Geothermal System?
The heat from the sun is absorbed into the earth, storing up to 50% of the sun’s energy. This clean source of renewable solar energy mixes with the heat from the center of the earth and creates energy that never runs out. According to energyhomes.org, this is how a typical geothermal system works:
A typical system consists of a ground loop system filled with a water solution, a heat exchanger, and ductwork into the building. During the winter, heat from the ground is absorbed by the water solution as it circulates through pipes in the ground. The warmed water is carried into the home where a water-to-air heat pump concentrates the thermal energy and transfers it to air in a conventional ductwork system, which is circulated to heat the home. In the summer, this process is reversed, and excess heat is pumped from the home either into the ground or redirected to heat domestic hot water in order to cool the home.
Why Choose a Geothermal System?
Ground temperatures remain relatively constant from 45 to 75 degrees. During the winter, the ground temperature is warmer than the open air and during the summer the air is cooler. This presents a perfect opportunity to keep the air in your home comfortable no matter the season using a Geothermal System. The consistency of underground temperature makes this system exceptionally efficient. In fact, gas furnaces are only 98% efficient whereas geothermal systems achieve 400 – 600% efficiency.
While geothermal units are slightly costlier upfront than traditional heat pumps, the long-term payback, and extended equipment life will be returned to you in the form of energy savings within 5 – 10 years. Compared to a traditional air source heat pump or gas furnace, a geothermal system consumes less energy, making it significantly more energy efficient at heating and cooling your home. Additionally, these systems qualify for a recently implemented federal tax credit allowing homeowners to deduct 30% of the total system installed cost from their tax liability.
