How It Works

How Geothermal Works

You already have a heat pump in your home - your refrigerator. If you put your hand behind it, you'll feel the heat that's being pumped from the inside.

It's the same principle that a geothermal heat pump uses to warm your home. Instead of producing heat like a conventional furnace, a geothermal heat pump moves heat from one place to another - from the ground into your home.
