Question: what is the difference between an electric heat pump and a geothermal heat pump?
Answer: Energy efficiency – Geothermal heat pump systems are more energy efficient. These heat pumps operate at between 300 to 600 percent efficiency even in the coldest weather. ... This is part of the reason a geothermal heat pump indoor unit lasts around 25 years, whereas the average air-source heat pump lasts around 15 years.
