Is Geothermal Heating Worth It?

Geothermal heating is becoming increasingly popular these days. If you’re reading this blog post, chances are you’ve heard of geothermal heating and are wondering if it really can save you money on your heating and cooling bills in Maryland.

The short answer is yes. But let’s rewind just a little.

What Exactly Is Geothermal Heating?

A geothermal heating system is electrically powered unit that transfers the heat stored in the ground to your home. With a geothermal heat pump, the system works in the reverse in the summer—using refrigeration to remove heat from your home. This system differs from air source heat pumps, which draw heat from the air rather than the ground.

This article from National Geographic explains it well:

“Outdoor temperatures fluctuate with the changing seasons but underground temperatures don’t change as dramatically, thanks to the insulating properties of the earth. Four to six feet below ground, temperatures remain relatively constant year-round. A geothermal system, which typically consists of an indoor handling unit and a buried system of pipes, called an earth loop, and/or a pump to reinjection well, capitalizes on these constant temperatures to provide “free” energy.”

Why Do Geothermal Heat Pumps Cost More than Air Source Heat Pumps?

The cost of a geothermal heat pump can be three to five times more than a typical air source heat pump system. This makes sense when you consider the installation process. To install a geothermal heat pump, you must drill into the ground to place the pumps’ loops—which carry the water and anti-freeze solution necessary to transfer the heat in the ground into your home.

Is Geothermal Heating Worth the Extra Cost?

A geothermal heat pump can be 30 to 50 percent more efficient than a typical heat pump—dramatically decreasing your monthly electric bills. According to the Department of Energy, you may recoup your initial investment in as little as two years through lower utility bills.

In addition, because geothermal heat pumps are an environmentally friendly heating and cooling option for your home, the government offers incentives and tax breaks in Maryland for residents who choose to install them. It is estimated that federal and local incentives can cover between 30 to 60 percent of your geothermal unit.
