Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange are ground or water-sourced heat pumps and have been in use since the late 1940s. They use the constant temperature of earth as the exchange medium instead of the outside air temperature. This will allow the system to reach fairly higher efficiencies compared to air-source heat pumps.
Although many parts of the country experience seasonal temperature extremes, a few feet below the earth’s surface remains a relatively constant temperature. The Geothermal Heat Pump exchanges heat with the earth through a ground heat exchanger. So what are the benefits of having a GHP instead of a water or ground sourced heat pump?
Benefits to Geothermal Heating:
Lower Utility Bills: Homeowners with GHP usually have energy savings of 25 to 50% over conventional systems. A 2000-sq.-ft. home can be heated and cooled for as little as $1 a day. In addition, a Geoexchange system can supplement a home’s water heater, saving up to 30% every year.
Environmentally Friendly: United States Environmental Protection Agency recognizes Geothermal as the most environmentally-safe, cost effective heating & cooling system on the market. By comparison, installing a geothermal system is equals planting 750 trees or taking two cars off the road.
Free Hot Water: Geothermal systems also have the ability to produce some or all of your hot water at much higher efficiencies. The heat removed from your home during the cooling cycle is deposited directly into the water heater.
Clean & Safe: Geothermal systems do not use fossil fuels. Remember how we said they are environment friendly?
Improved Comfort: Geothermal systems heat and cool homes evenly. This eliminates the blasts of air found with conventional systems. They can also dehumidify the air during hot summer months.
