"How do geothermal systems work?"
Like any type of heat pump, a geothermal simply moves heat energy from one place to another. Your refrigerator works using the same scientific principle. Using a unique earth-friendly “refrigeration”, the geothermal heat pump transfers energy to the home by removing heat energy stored in the earth and groundwater.
Geothermal heat pumps also take advantage of the mild ground temperature for extremely high efficiency cooling. Most systems also include a hot water generator, which diverts a portion of the supplied heat to the domestic water heater. This provides a substantial portion of a family’s hot water needs at a very low cost. Overall, geothermal technology offers the highest cooling and heating efficiencies of any system available.
"Do geothermal systems BOTH heat and cool?"
One of the things that makes a heat pump so versatile is its abitlity to be a heating and cooling system in one. You can change from one mode to another with a simple flick of a switch on your indoor thermostat. Plus, a geothermal heat pump can assist in heating hot water year-round. A geothermal unit typically supplies four to five killawatts of heat for every killawatt used. Three to four of these kilowatts of heat come directly from the earth itself, and are clean, free and reusable.
