GE's GeoSpring hot water heater uses heat pump technology, so it only runs on electricity. Heat pump technology can offer significant energy savings over traditional electric water heaters.
Heat pumps works by drawing heat out of the ambient air. As a result, they function more efficiently in warmer zones. GE's GeoSpring hot water heaters use heat pumps in addition to traditional electric heating to ensure a steady supply of hot water. Despite their energy savings, heat pumps used indoors draw some heat from the structure, leading to a bit of cooling. As a result, heating bills might go up a bit in colder areas. Homeowners who need air conditioning, on the other hand, may see slightly lower cooling costs.
