There’s an invaluable energy source buried right in your own backyard: the earth itself. Forget oil or gas; geothermal systems tap into the relatively consistent temperatures of your yard, pond, or well. This ingenious technology runs on electricity but uses the earth’s thermal energy to pre-condition refrigerant used to heat and cool your home so you can enjoy higher energy efficiency inside – no matter how extreme the weather gets outside. Call Midwest Mechanical today to install a geothermal system.

    Benefits of Installing a Geothermal System in Your Home

    Installing a geothermal system in your home offers a range of environmental, economic, and efficiency benefits that make it an attractive alternative to traditional heating and cooling methods. Here are some key advantages of choosing a geothermal system:

    • Energy Efficiency: Geothermal systems are highly efficient because they use the consistent temperature of the earth to heat and cool your home. This means they require less electricity to operate compared to conventional systems, potentially reducing your energy consumption by up to 60%.
    • Cost-Effective: Although the initial installation cost of a geothermal system can be higher, the long-term savings on energy bills make it a cost-effective choice. These systems have lower operational costs because they are less dependent on fluctuating prices of fossil fuels.
    • Eco-Friendly: Geothermal systems are a green technology that significantly reduces your carbon footprint. By utilizing the earth’s natural heat, they emit fewer greenhouse gases than systems relying on gas or oil.
    • Reliability and Longevity: Geothermal units are known for their durability and require less maintenance than traditional HVAC systems. The underground components of a geothermal system are typically warranted for up to 50 years, while the indoor components can last over 20 years.
    • Quiet Operation: Unlike traditional HVAC systems that can be noisy, geothermal systems operate very quietly, creating a more comfortable and peaceful home environment.
    • Improved Indoor Air Quality: Geothermal systems provide consistent air circulation, reducing humidity levels inside the home and minimizing the presence of indoor allergens such as dust and mold.

    These benefits make geothermal systems an excellent investment for homeowners looking for a sustainable, efficient, and cost-effective solution to heating and cooling their homes.

    Geothermal Systems vs. Traditional HVAC: A Comparison

    When deciding between a geothermal system and a traditional HVAC system for your home, it’s important to consider the key differences that can affect performance, cost, and environmental impact. Here’s a concise comparison to help guide your decision:

    • Energy Efficiency: Geothermal systems are generally more energy-efficient than traditional HVAC systems. They use the stable underground temperature to regulate your home’s climate, which requires significantly less electricity and can save you up to 60% on energy bills compared to conventional systems.
    • Initial Costs and ROI: Initial installation costs for geothermal systems are higher due to the need to install underground loops. However, the return on investment is favorable, as lower operating costs and energy savings can offset the initial expense over time. Traditional HVAC systems have lower upfront costs but tend to have higher monthly operating costs.
    • Environmental Impact: Geothermal systems have a minimal environmental footprint since they harness natural heat from the earth and do not rely on burning fossil fuels. Traditional HVAC systems, especially those that use gas or oil, have a higher environmental impact due to carbon emissions.
    • Lifespan and Maintenance: Geothermal systems typically have a longer lifespan; the underground loop systems can last up to 50 years, and the indoor components can last about 20-25 years with minimal maintenance. Traditional HVAC systems usually need more frequent repairs and replacements every 10 to 15 years.

    Space Requirements: Geothermal systems require sufficient land for the installation of the ground loop. In contrast, traditional HVAC systems are less demanding in terms of space but may require areas for external compressors and ventilation units.

    Energy Source Options

    Open Loop

    In ideal conditions, an open-loop application can be the most economical type of geothermal system. These use groundwater from a well as a direct energy source.

    Closed-Loop Horizontal

    If enough land is available horizontal loops can be installed. One or more trenches are dug using a backhoe or chain trencher. HDPE pipes are inserted, and trenches are backfilled. The more pipe per foot of the trench, the shorter the trench can be. Trenches range from 100 to 300 feet.

    Closed Loop Vertical

    Vertical loops are installed if land space is limited and/or soil content is not conducive enough for horizontal loops. Installing vertical loops requires the use of a drilling rig. Multiple holes are drilled (depending on the size of the home) about 20 feet apart. A double pipe connected by a U bend at the end of the pipe is inserted in the hole. The hole is then filled with grout to provide good contact around the pipe and to seal the hole. The pipes are connected by a header system a few feet below the ground, which are then brought in through the foundation of your home and connected to the unit. The typical drilling depth is 100′-200′.

    Pond Loop

    If you have access to an adequate size body of water close to your home, a pond loop can be installed. A series of earth loops are coiled and then sunk to the bottom of the pond. Typically a 1/2 acre with 8′ depth is usually adequate. Ideally, the body of water needs to be within 200′ feet of your home. If the pond is further than the recommended 200′, the benefit of using a pond loop is greatly reduced because of trenching, materials, and pumping costs.
