The benefits of heat pumps compared to conventional heating sources is well documented. The question is, what are the benefits of a geothermal heat pump compared to an air-source heat pump? Following are several factors to consider when deciding which type of heat pump works best for your Marshville, NC, home.

Efficiency

Because a geothermal system takes advantage of the heat from the ground, it can produce more heat for less electricity than an air-source heat pump. Geothermal systems take heat from the ground, which averages 45 degrees. Air-source units take heat from the outside air; this means that in January, when Marshville temperatures drop to 31 degrees, the air-source heat pump has to work harder to produce the heat you need.

Maintenance

Geothermal systems require less maintenance than air-source systems. They have fewer components, and the parts are either inside your home or underground, where they are protected from damage. Air-source heat pumps have an outdoor unit that requires regular service and is subject to damage.

Pricing

Geothermal heat pumps cost more to install than air-source heat pumps due to excavation costs and the cost of the looping system. You’ll recoup your upfront cost in five to 10 years through energy savings. Tax incentives for geothermal systems also help offset the higher cost. Additionally, the geothermal indoor unit has a life expectancy of 25 years compared to 15 years for an air-source unit.

Space

The indoor units on both types of heat pumps take up the same amount of space, but a geothermal heat pump requires more land than an air-source unit. As a general guideline, for a mid-sized, Marshville, home, you need about 1,500 to 1,800 feet of trench. Your lot’s subsoil and rock composition are also factors in whether a geothermal system would work for you.
