How It Works: Anatomy of a Geothermal Heat Pump

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.

What It Is: The Geothermal Process

The geothermal process is based on a simple premise: Below the frost line - usually about six feet deep – the earth is a constant temperature of about 50 degrees Fahrenheit all year long.

During the winter, the heat pump absorbs heat from the ground and uses it to warm the air in your home. In the warmer summer months, the processed is reversed, taking heat from your home and transferring it back into the ground.

The basic elements of a geothermal system include:

		Underground loops of plastic piping
		A liquid antifreeze solution
		A heat pump
		An air distribution system

The loops of piping are buried in the ground near your home or business, either vertically or horizontally. That ground loop is connected to a pumping module inside your home.

The pump circulates a mixture of water and the antifreeze through the ground loop, where it absorbs heat from the earth.

When the heated liquid reaches the heat pump inside your home, the heat is multiplied and used to warm the air inside the air-handling system. A blower sends the warmed air throughout the building through ductwork.
