The Benefits of Owning a Geothermal System in Ann Arbor, Michigan

Geothermal Repair in Ann Arbor, Michigan

WaterFurnace geothermal systems are the “hottest thing going” today when it comes to cooling and heating your home, particularly for those who are environmentally conscious and want to enjoy a comfortable home year-round while conserving energy, and saving money.  If you aren’t familiar with the benefits of geothermal systems, Haley Mechanical wants to enlighten you about a few of the benefits.

Increased comfort.  Many homeowners in Ann Arbor, Ypsilanti, and surrounding areas experience cold spots in winter months and hot spots in their homes in summer months.  With a WaterFurnace geothermal system, comfortable air is evenly distributed throughout your home, eliminating hot or cold spots.  In winter months, you enjoy warm comfort without hot blasts you may experience with a traditional gas furnace.  In summer months, geothermal systems deliver air that is not only cool and refreshing but dehumidified as well.

Lower energy costs.  Geothermal systems work by combining energy that is stored below the ground with safe electric power, ultimately delivering five units of energy to cool and heat your home for every one unit of electrical energy.  This combination helps Michigan homeowners save an astounding amount of money – up to 70% on costs for hot water, cooling, and heating.

Dependable.  Traditional air conditioners and heat pumps have components installed outside, subjecting these components to rain, ice, extreme temperatures, and other elements that create wear and tear over time.  Geothermal units are installed inside, so they are protected from these elements and require less maintenance.

Quiet.  If you would enjoy quiet operation without the buzz and roar typically experienced with traditional air conditioners, you will love the WaterFurnace geothermal system as it is designed to run quietly.

Eco-friendly.  We have already mentioned geothermal systems are environmentally friendly, but even more, they emit no greenhouse gasses, carbon monoxide or dioxide, or other chemicals or poisons that contribute to air pollution.  When it comes to heating and cooling your home, a geothermal system is highly recommended by the EPA and Department of Energy.  There is no “greener” way to enjoy home comfort and reduced energy costs!

What is the Difference Between Geothermal Open Loop and Closed Loop?

A Globe of the Earth

In part three of our Introduction to Geothermal series, we are going to discuss geothermal loop systems and how each type works.

A geothermal loop is the series of underground pipes used to move heat to and from the earth. The pipes are made out of high-density polyethylene to establish a dependable, long-lasting system. They are joined together by the process of thermal fusion that will develop a bond that is far stronger than the original pipe itself. In fact, a properly installed loop can remain up to 200 years.

There are two main types of geothermal loop systems that are almost always used in today’s installs: open loop systems and closed loop systems. Each system has different pros and cons for your heating or cooling solution. We at Haley Mechanical have the training and experience on both types, and we will guide you step by step in the process of determining the right option for your geothermal installation.

Open loop geothermal solutions are designed to maximize the natural groundwater from underneath your home. Using a well, water is pulled from an existing aquifer and delivered to the geothermal heat pump where its heat is extracted, and the water is pushed back into the ground or to a designated runoff. Since the water that you are handling is not being treated in any way, the only thing that is being returned to the earth is water that is slightly warmer or cooler (depending on whether you’re in heating or cooling mode).

One thing to keep an eye on with an open loop system is water quality. Mineral build-up can manifest from the poor quality water. This can be attended to with occasional cleaning. If the water in the earth has higher iron content, you will need to make sure that the discharge water is prevented from coming in contact with air before it is returned to prevent clogs.

The only thing that you need to watch out for when it comes to an open loop system is a mineral build-up if the water’s initial quality is not very good. This can easily be attended to with an occasional cleaning with a mild acid solution. If the water in the earth has a higher iron content, you will need to make sure that the discharge water is prevented from coming in contact with air before it is returned to prevent clogs.

Closed loops are exactly as they sound. Instead of pumping water from a well and depositing it elsewhere, water is circulated in an entirely sealed circuit with a small amount of environmentally-friendly antifreeze.

There are two primary types of closed loop installations: horizontal and vertical. Putting in the system horizontally requires a good chunk of land. The piping is embedded in trenches between 4 and 6 feet deep and can be up to 400 feet long. If you reside on a smaller lot, the loops can be installed vertically by boring straight down using drilling equipment. This kind of installation can be installed in as little as a 10ft by 10ft area.

In either case, the larger the building, the larger the geothermal heat pump and loop need to be. A good ballpark figure is that for every ton of system capacity, you will need 500 to 600 feet of pipe.

Open Loop vs. Closed Loop Geothermal Systems

Geothermal Heat Pump Installation

Ground source geothermal heat pumps have become highly popular in recent years for home comfort and other benefits. In fact, each year more homes in the U.S. switch from standard air source heat pumps to ground source geothermal systems. At Haley Mechanical, we understand why so many homeowners are making the switch, and the exceptional benefits of geothermal systems – reduction in harmful emissions, long lifespan, outstanding performance and energy savings, and efficient heating even during the most frigid winter temperatures in Michigan.

What is the difference between open loop and closed loop geothermal systems?

An open loop system consists of a pipe that is buried beneath the ground using nearby groundwater for the heat exchange process. Unlike a closed loop system that circulates a mixture of anti-freeze and water, the water does not circulate but instead is directed into drainage after use.

With a closed loop system, a pipe is also buried beneath the ground. However, a mixture of water and anti-freeze is circulated to cool and heat your home. Essentially, the water/anti-freeze solution either deposits or absorbs heat from the ground, depending on the season. The solution enters a heat exchanger located inside your home that transfers heat via the refrigerant in the heat pump. With a closed loop system, loops are placed according to the space available, and depending on your situation will be laid either as vertical loops after drilling or in a horizontal configuration.

While the type of geothermal system that’s right for you depends on some factors including groundwater availability, closed-loop systems are the most common. Not only is a water source essential for an open loop system, these loops may collect debris inside the piping system that can result in repair issues and costs. Your installation professional can guide you regarding the differences between an open or closed loop geothermal heat pump system, and which is best in your situation.

At Haley Mechanical, we realize that geothermal heating and cooling systems are something still relatively new to southeast Michigan homeowners. Have questions regarding home comfort, energy savings, and the benefits of this type of system to the environment? Give us a call today!
