Compared to other HVAC systems, geothermal systems have a much lower life cycle costs no matter where you live.

Our company specializes in the installation of WaterFurnace geothermal systems for residential, and light commercial. According to the US Department of Energy (DOE), geothermal systems save homeowners as much as 50 percent on their cooling costs and up to 70 percent on their heating costs when compared to conventional systems.

Types of Loop Systems

There are two general types of geothermal loop systems: closed and open. Open-loop systems in our geographic location tend to be more problematic due to poor groundwater quality. That's why we traditionally recommend closed-loop systems. All loop systems are created equal and no one loop is better than another as long as it gives you the required heat transfer in the ground.

In closed-loop systems, there are several installation methods to achieve a closed-loop. There are many opinions about what type is the best. The final answer is all loop types are created equal! Horizontal or vertical, slinky, or straight pipe, these loops are equal because they are designed to be equal. As long as your loop is designed to reach a certain EWT (or entering water temperature) to be determined by your local installer, and to exchange between 5 and 10 degrees Fahrenheit, then the loop will work. The best loop is the loop that fits your needs and budget.

Closed Loops

Closed-loop systems are the recommended geothermal installation method in the Maryland area. In this type of system, water or a water and antifreeze solution is circulated through a buried pipe. The length of the pipe depends on a variety of factors, including the ground's thermal conductivity, temperature, and moisture levels. When installed properly, closed-loop systems are efficient, economical, and reliable.

Open Loops

In an open-loop system, groundwater is drawn up from one well via an aquifer, which passes the water through the heat pump's heat exchanger and is finally discharged to the aquifer through a second well that is located a short distance from the first.

For an effective heat exchange, 2 to 3 gallons per minute per ton of capacity are typically necessary. Because the temperature of groundwater is nearly constant throughout the year, open-loop systems are a popular option in areas where they are allowed and have been used successfully for decades. However, there are several challenges associated with open-loop systems:

The chemical conditions of some local groundwater sources can foul the heat pump's heat exchanger. In these situations, extra precautions may be needed to keep gasses in solution in the water source.

Water use and discharge methods must be cleared with local officials to ensure compliance with environmental regulations and concerns. Increasing environmental concerns mean that local officials must be consulted to ensure that you comply with all regulations concerning water use and accepted water discharge methods. It's rarely acceptable to discharge wastewater to a sanitary sewer system.

Horizontal Loops

For small installations where there is adequate land available, horizontal loops are usually the most cost-effective option. In this type of system, up to six pipes are buried in trenches in parallel connection with at least one foot between pipes and 10 to 15 inches between each trench. Slinky-style loops are also very common.

Vertical Loops

In many situations, vertical closed loops are the preferred solution because They require very little space. Ground Loop Heating and Air Conditioning has even installed vertical loops directly in a driveway on a 1/8th of an acre, and its townhouses. For example, many schools and commercial buildings rely on vertical loops because a horizontal loop system would simply require too much space.

Because of small size, vertical loops are the most common. Depending on the ground conditions, the length of the loop can vary between 200 and 400 feet deep of vertical drilling.

There are two styles of vertical drilling that are used in our area. Air rotary drilling utilizes high-pressure air to drill through hard rock structures and is commonly used in areas west of route 95. Mud rotary drilling uses recirculated high-pressure water to drill through mud, sand, clay, and gravel and is generally used east of route 95.

Pond Loops

Pond loops are a type of closed loop system that takes advantage of an existing pond or stream. If the body of water is deep enough and has enough flow, then a system of closed loop coils can be placed on the bottom of the pond. The fluid is then pumped as with a conventional closed loop ground system. Pond loops have not been shown to damage nearby aquatic systems and they are an economical option when the conditions are suitable.
