Geothermal heating is becoming more and more popular — and for good reason. Many homeowners are realizing the advantages these systems offer. If you’re curious about how you can harness the earth’s natural power to run your HVAC system, the overview below will give you the basic information you need. 

What Is Geothermal Heating? 

Standard gas furnaces and water heaters rely on the chemical reaction of combustion to generate heat. Geothermal power instead taps into the heat that occurs naturally underground. The temperature of the subsurface remains relatively constant no matter the season, even at surprisingly shallow depths, so energy can be drawn from it at any time. Some residential systems drill a well to reach ground water in what’s known as an open loop system. Others use a closed loop system that either extends horizontally or reaches vertically far into the earth. Still others rely on nearby ponds or lakes. All configurations contain a heat pump with an exchanger and a distribution mechanism, like ductwork. Geothermal power can be used for conditioning air, heating water, or generating electricity.

What Are Its Advantages? 

Geothermal heating comes with many perks. Unlike many other power sources, it’s a renewable and likely inexhaustible resource. It produces far less greenhouse gas emissions and burns much less fossil fuel. The systems are incredibly efficient, requiring 30 to 60% less energy than regular HVAC systems. They’re cost-effective, since they’ll reduce your monthly utility bills. Federal tax credits may even be available to reduce upfront installation expenses. They components themselves require little maintenance, and some parts can come with warranties. 

Who Should Use It? 

Any homeowner who wants to reap the benefits above should consider making the switch to a geothermal HVAC system. This option is ideal for those who plan to stay on their properties long enough to see returns on their investment, which generally occur within 5 to 10 years. It’s particularly excellent for homeowners who live on large lots with access to water sources, but plans can be adapted to suit varying circumstances.
