How Geothermal Works

Different Systems Available for Installation of a Closed Loop Residential Geothermal System:

Vertical Closed Loop Geothermal System

In a vertical geothermal system, deep boreholes are drilled into the ground, typically ranging from 100 to 400 feet. A loop of pipes, filled with a heat-transfer fluid, is inserted into the boreholes. During winter, heat is absorbed from the ground and transferred into the home via a heat pump. In summer, the system reverses, transferring heat from the home into the cooler ground. This method is ideal for properties with limited horizontal space.

Horizontal Closed Loop Geothermal System

A horizontal geothermal system uses loops of pipes buried in shallow trenches, typically 4 to 6 feet deep, across a wide area of land. The heat-transfer fluid circulates through the pipes to absorb or release heat from the ground, depending on the season. This method is more cost-effective to install but requires a larger land area, making it suitable for properties with sufficient open space.

Pond/Lake Closed Loop Geothermal System

A pond or lake loop geothermal system utilizes an existing body of water as a heat exchange medium. Coils of pipe are submerged in the water, allowing the heat-transfer fluid inside the pipes to absorb or release heat to the water, which maintains a relatively stable temperature year-round. This system is often more cost-effective than drilling for vertical systems, provided there is a suitable pond or lake nearby. It works similarly to other geothermal systems but uses water as the heat source or sink instead of the ground.

General FAQs

What is a geothermal system?

A geothermal system uses the earth’s stable temperature to heat and cool your building. It extracts heat from the ground in winter and releases heat back into the ground in summer, providing an energy-efficient heating and cooling solution.

How much does a geothermal system cost?

The cost depends on factors like system type, property size, soil conditions, and whether you’re installing a new system or replacing an existing one. We offer free estimates and work with you to create a cost-effective solution.

How long do geothermal systems last?

Geothermal systems are durable and can last for 25 years or more for the indoor components, and the loop system (outside portion) can last 50 years or longer with proper maintenance.

Can I install a geothermal system in my existing home?

Yes, geothermal systems can be retrofitted into existing homes, though the installation process might be more complex depending on the property’s layout and available space for the loop system.

Are geothermal systems environmentally friendly?

Yes! Geothermal systems use renewable energy from the earth, reducing greenhouse gas emissions and providing a low-impact heating and cooling option. They are highly efficient, helping to reduce your carbon footprint.

How does a geothermal system compare to traditional heating and cooling systems?

Geothermal systems are more energy-efficient than traditional heating and cooling methods, saving you money on energy bills over time. They also require less maintenance and have a longer lifespan.
