Are you looking for a cost-effective way to maintain a comfortable temperature in your home in Northbrook, Illinois? If so, consider installing a geothermal system. Also known as geothermal heat pumps, geothermal systems are rapidly gaining popularity because of their excellent energy efficiency and environmental friendliness. Read on to find out how a geothermal system works to keep your home comfy.

What’s a Geothermal System?

A geothermal system refers to an electrically powered refrigeration system that uses energy from the ground to cool or heat your home. Several feet beneath the surface of the Earth, the temperature stays between 50 and 60 degrees. It’s higher than the temperature above the ground in the winter and cooler in the summer. A geothermal heat pump takes advantage of this constant source of heat by transferring and concentrating heat energy to cool and warm your home.

How Does a Geothermal System Work?

A geothermal system consists of three main components: a heat pump system, ground heat exchanger, and ductwork for delivering air. The ground heat exchanger is made up of a series of pipes, which are collectively known as a loop. The pipes are installed several feet under the ground and contain a fluid comprising water and antifreeze. The fluid circulates through the loop to absorb heat from or disseminate heat into the ground. The antifreeze in the fluid helps prevent freezing in the winter.

The heat pump works in a similar way to a refrigerator. A refrigerator makes the space inside it cooler by transferring heat to the space surrounding it. In the winter, a geothermal heat pump draws heat from the ground heat exchanger and pumps it into the ductwork to keep your home warm and comfortable.

The process reverses in the summer. The heat pump extracts heat from inside your home and channels it into the ground heat exchanger, which will, in turn, dump the heat beneath the ground. You can also use heat drawn from inside your home to heat water in the summer, providing you with free hot water throughout the season.

What are the Benefits of a Geothermal System?

While a geothermal system has a higher upfront cost than a typical HVAC system, it offers many benefits that make it a worthwhile investment in the long run. These benefits include:

Comfort

A geothermal heat pump uses an air handler with low and continuous cycling. That results in an even distribution of conditioned air throughout your home. This means you’ll never experience the cold and hot zones that commonly occur in homes that use forced-air HVAC systems.

Air Quality

Since a geothermal system doesn’t need the influx of outdoor air to keep your home comfortable, it helps reduce the amount of pollutants that sneak indoors. As such, you’ll be able to enjoy better air quality and avoid a wide range of health issues that can result from indoor air pollution.

Cost-Effectiveness

In certain climates and situations, a geothermal system can perform at a six-to-one ratio. That means it can produce six times the heat for every unit of electricity used. This will amount to substantial energy savings over time. Also, you may be eligible for tax credits and local utility rebates if you opt for an Energy Star-certified system.

Longevity

While the average lifespan of a standard HVAC system is 13 to 15 years, a geothermal heat pump can last about 24 years. Since you don’t have to replace it as often, it gives you more bang for your buck.

The benefits of geothermal systems are overwhelming. If you want to replace your current heating and cooling unit with a geothermal heat pump, make sure you get a high-quality system from a reputable company.
