Although a geothermal heat pump is extremely expensive to purchase and install, it can save you a tons of money in energy costs. The system operates a lot like a refrigerator. A refrigerator simply removes heat from the interior of the unit and transfers it out, into the kitchen. The geothermal heat pump relies on the same principle, transferring heat from the ground to the home. It manages this through extensive loops of underground pipes, which are filled with a combination of water and an antifreeze solution. The loops are then linked to a geothermal heat pump, which is installed inside the home, and provides both heating and cooling capability. When in heating mode, the liquid extracts heat from the ground and supplies it to the geothermal heating/cooling unit and then to refrigerant coils. The heat is distributed through a forced air system and evenly spread throughout the house. During cooling mode, the operation is reversed to pull heat from the house and transfer it into the ground. This process is exceptionally safe, quiet, clean and effective. The geothermal heat pump won’t overly dry the air during the winter, avoiding the need for a humidifier. In the summer, the unit helps to combat excess humidity, allowing higher thermostat settings and preventing issues with condensation, mold and mildew. A geothermal heat pump is far more energy efficient than conventional heating and cooling equipment. It doesn’t burn fossil fuels to create heat, but simply moves existing heat from one place to another. Since the temperature underground holds steady at around fifty degrees Fahrenheit all year round, the geothermal heat pump takes advantage of this free energy source.
