Geothermal energy is a renewable energy source that offers clean and efficient power taken from the heat generated by the Earth’s core. You might have considered geothermal energy as out of your personal reach—it’s something you get from geothermal power plants, but you can’t imagine using the geothermal energy from right around your house for anything useful.
Good news! Geothermal energy is more accessible for your home than you may think. One of the most useful geothermal installations is a geothermal heat pump to provide your house with heating and cooling around the year. Indoors, a geothermal heat pump works similarly to a standard air-source heat pump—it releases heat or absorbs heat through a refrigerant coil and then a blower sends the conditioned air into the ductwork. But instead of an outside unit, a geothermal heat pump has loops buried in the ground (at least 6 feet below the surface) to both access and deposit thermal energy.
