What Are the Benefits of Geothermal Heating

Geothermal heating is a relatively new and promising alternative to traditional heating, ventilation, and air conditioning (HVAC) units. While these systems can have a hefty upfront cost, the many benefits they provide make the system more than worth it.

Check out what makes geothermal systems so great below!

How it Works

To understand the benefits of Geothermal pumps, you first must know how they work.

Geothermal heating utilizes either a closed-loop or open-loop piping system that is buried on the property and opens into a nearby water source. These pipes are filled with fluid that helps with the heat exchange.

The system uses the liquid in the loop to draw heat from the ground, unlike conventional units which use outside air. This fluid is then pumped through the loops into the heat pump, which is located inside the home. The pump's heat exchanger then uses energy from the ground to warm the air, which is then circulated through the ductwork.

The Benefits

Environmental Friendly

One of the main benefits of a geothermal system is that it is a substantially greener way to heat and cool your home. These systems don't emit any carbon monoxide or any other greenhouse, which significantly reduces your carbon footprint. A geothermal heater will also require less electricity than other units, which is excellent for the environment.

Cheaper to Run

While the costs of purchasing and installing geothermal systems will be higher than most units, it does have lower operating costs. Because the system is cheaper to run, this will not only lead to you making your money back, but you will actually save some in the process.

Tax Credits

These systems are not just cheaper to run; they also make you eligible for government tax credits, which will help you recoup your money quicker.

While this is an excellent bonus for installing the system, the amount of tax credit you receive has continually declined over the years. In the past, you would receive as much as 30% of what you spent on purchasing and installing a geothermal heat pump. Since 2021 the tax credit has sat at 26% and will be dropping again to 22% in 2023, so it's best to act fast.

Longer Lifespan

Geothermal heating has a substantially longer lifespan when compared to conventional HVAC units. On average Geothermal systems can last anywhere from 20-25 years compared to just 10-15 years for traditional units.

Runs Quietly

If you're someone who likes a nice quiet home, then Geothermal systems are the way to go. This is because these systems don't need outdoor condensing units, and the indoor part is designed to operate quietly.


Unlike conventional systems, geothermal heating doesn't rely on combustible fossil fuels to heat the home. This means that there is no need to worry about dangerous carbon monoxide potentially escaping the system and causing carbon monoxide poisoning.

Improved Air Quality

Geothermal systems actually provide better comfort than the average HVAC unit. Geothermal heat pumps don't bring air in from the outside, which allows for fewer contaminants to enter your home.

While traditional systems will turn on and off based on your home's temperature, geothermal systems run continuously, allowing them to keep your home at the ideal humidity. This prevents mold and mildew from growing, which can cause congestion, throat irritation, coughing, and other respiratory issues.
