Geothermal Heat Pump: What Is It and Why Is It Special?

The geothermal heat pump is one of the best HVAC units there is. It doesn’t burn any fuel for heating, but rather harnesses clean energy beneath your feet: the earth. It can also cool your home in the summer. When it’s hot, it pulls the heat from your home, cools it below ground and pumps chilled air to your rooms through the ducts.

Geothermal Heat Pump: What Is It and Why Is It Special?

Here are some of the most notable advantages of the geothermal heat pump system:

It Is Useful in Any Climate

The temperature of shallow ground usually stays at 54° F all year long. Compared to air-source heat pumps, geothermal units are more reliable because their energy supply is stable regardless of the surface’s temperature.

Its heat exchanger—a loop of pipes buried several feet down—contains fluids that absorb heat from the ground. During winter months, the heat pump extracts heat from the earth to warm the much cooler air. In the summer, when the air above the surface is hotter than the ground, it works in reverse.

It Helps Reduce Carbon Emissions

Considering its superiority to traditional HVAC units in terms of energy efficiency, the geothermal heat pump system can reduce your home’s peak electricity demand. In turn, it helps ease the load on the electric grid, minimizing the pollutants produced when generating electricity.

It Lasts a Long Time

Its indoor components can remain in good shape for about 25 years. Its ground loops can last twice as long because the earth protects them from the weather.

It Pays Itself Back Within 10 Years

Upgrading to a geothermal heat pump system can be a costly proposition, but it pays for itself with guaranteed energy savings. According to the Department of Energy, you can recoup your expense usually in just a decade.
