Heat pumps are the most efficient form of electric heating in moderate climates, providing up to three times more heat than the energy they use. A heat pump can reduce your electricity use for heating by 30%-40% compared to electric resistance heating such as furnaces and baseboard heaters.

A heat pump does double duty as a central air conditioner by collecting the heat inside your house and pumping it outside.

There are three types of heat pumps: air-to-air, water source, and geothermal. They collect heat from the air, water, or ground outside your home and concentrate it for use inside.

Geothermal (or ground source) heat pumps have some major advantages. They can reduce energy use by 30%-60%, control humidity, are sturdy and reliable, and fit in a wide variety of homes.
