Geothermal Ground Loops

Even Temperatures with Geothermal Ground Loops

Are you interested in an eco-friendly, renewable, and cost-effective alternative to traditional heating and cooling services?

Geothermal ground loops – comprising a heat pump, ductwork, and system of submerged pipes – tap into the earth’s natural, consistent heat storage to alternately heat and cool residential and commercial properties.

In the winter, systems pump warm air from a heat exchanger indoors. In the summer, the process is simply reversed.

Did you know that consumers who install geothermal heat pumps can receive a 30% federal tax credit for systems placed in service before December 31, 2019. The credit decreases to 26% in 2020 and 22% in 2021.

The state of Maryland offers Clean Energy Grant incentives as well.  So call us today to maximize your credits.

Types of Geothermal Ground Loops

Our crews specialize in drilling and installing both closed loop systems, which recirculate a water/refrigerant hybrid for heating and cooling purposes, and open loop systems – which rely on well water as a source of heat exchange.

Horizontal loops
When space is not an issue, horizontal ground loops are an incredibly economical and efficient option. Several hundred feet of trenches are dug 6 to 10 feet deep. Looped piping is then buried in the trenches. Horizontal loops are common configurations for new homes and commercial properties that have acreage to spare, but are not advised for erratic climates due to the shallow trenches.
Vertical loops
Vertical loops are frequently used in urban areas and small lots that have space restrictions. Holes, approximately 150 to 400 feet deep, are drilled at 20-foot intervals. Piping is then placed in these holes and connected via a u-bend fitting, forming a loop. Though more expensive than horizontal systems, they are considered a more viable and economical option in the long run, as they require less piping for proper heat exchange.
Slinky loops
This closed loop system, named for the “world’s most wonderful toy” it resembles, utilizes overlapping coils of piping laid out along a wide trench. An ideal space saver, slinky loops offer significantly more volume per foot of ditch.
Pond loops
Cost-effective and incredibly efficient, pond loops are an ideal choice for those who have access to a body of water that is at least 8 feet deep. Slinky coils of pipe are lowered into the pond on a skid, along with a heat exchanger. A trench is dug from the home or property to the sunken coil in the pond, closing the loop.
Open loops
In open loop systems, well water (or surface water) is used for a heat exchange fluid, returning to the ground via a well, recharge well, or surface discharge after being recirculated. Open loop systems rely entirely on an ample and clean supply of ground water.
