In the summertime, the system works in reverse. The pipes take this warmed water into a home where the heat pump converts the heat from the water into the air that it then pumps throughout the home to heat it. In the winter, the water solution absorbs the heat from the ground, and as it travels through the pipes underground. Geothermal heating and cooling units take advantage of this constant temperature by harnessing the heat and then either transferring it to a home to heat it or creating a heat sink so the home cools.Īverage geothermal heat pump systems have a ground loop system with a heat exchanger, water solution, and ductwork that leads to the building. Once you get twelve feet underground, the temperature remains the same regardless of the air temperature above it. The temperature a few feet below this surface, though, stays steady. You can experience the extremes of both heat and cold even in a single environment. The moving air above the earth’s surface constantly changes temperature. What is Geothermal Heating and Cooling and How Does It Work? When you use geothermal heat pumps, you help save the planet, save yourself money, and harness a renewable energy resource. Geothermal heat has much to do with this growth and catapult into the twenty-first century. Once a poor country that relied on fisheries for its economic growth, Iceland has tapped into its natural reserves of heat energy and is now has a thriving economy that depends heavily on tourism. Of that 85 percent, 66 percent of the energy came from geothermal sources. In 2014 approximately 85 percent of Iceland’s energy use came from renewable resources. Iceland is a country known for its smart use of renewable resources. Geothermal Heat Pumps: Why You Need a Geothermal Heating and Cooling System
