The capacity of your unit needed to facilitate the size of your home will determine the most significant portion of your budget. The larger the size, the higher the cost will be.
You can have a range of about 2. Generally, a home will need a unit between the ranges of 2. You also have to consider the types of loops for your geothermal heat pump. The space you have available will determine whether a horizontal or vertical system is the ideal choice for you.
Usually, horizontal loop systems are more cost-effective than a vertical loop. Still, there needs to be adequate space for horizontal loop systems to be installed. The features of your unit and system efficiency will also be a factor in determining overall costs. Popular features that homeowners look for include domestic hot water production, Wi-Fi control, and remote monitoring features. This cost would cover a complete geothermal installation.
It is crucial to remember that the size of your home, the location, types of soil, available land, local climate usability and condition of existing ductwork, and your choice of heat pump will influence the total geothermal heating cost required to invest.
All these factors also contribute to the geothermal heat pump cost that a homeowner can expect to spend during installation. As against the geothermal cost of about a decade ago, the pricing structure is becoming more competitive, thanks to the fact that there are more manufacturers offering ground source cooling and heating systems, and more experienced and efficient installers.
This cost would cover a complete geothermal installation. It is crucial to mention that the size of your home, the location, types of soil, available land, local climate usability and condition of existing ductwork, and your choice of heat pump will influence the total geothermal heating cost that you would be required to invest.
As mentioned earlier, there are different factors that can influence the exact cost that a homeowner invests in their geothermal system. This is also known as forced air systems. During the winter season, heat gathers with water that circulates in the pipes underground and gets converted to air that is being forced by a blower fan through the ductwork of your home.
The reverse is the case in summer; heat is gathered from the air in the home and transmitted into the water in underground pipes.
This gets cooled by the stable temperature underground before it is transferred into the home. This refers to hydronic systems where heat is transmitted between water in the loop system and the water in the baseboard heat system or indoor radiant heat floor system.
Basically, geothermal heat pumps, also known as ground source heat pumps GSHPs accumulate heat from underground to heat up your home and diffuse heat in the ground when cooling your home. As could be seen in the geothermal heating and cooling cost structure above, a high percentage of the cost is the loop system installation.
Basically, there are two types of loop systems; horizontal and vertical. Horizontal loops systems come with a series of coiled plastic pipe that is laid in horizontal troughs deep in the ground. The troughs have to be deep enough to prevent freezing and make the best of the constant temperature below the surface. The horizontal loops systems come at lower installation costs. Ground Loop Equipment Geothermal ground loops are installed using either drilling or trenching equipment based on the loop type and depth.
Drill Rig. A drill rig is a scarce resource that can only be used in one place at a time. Unlike backhoes or chain trenchers, drill rigs are a major expense to purchase or lease and require extensive upkeep, labor, and fuel to safely operate.
Mobilization Fee. One of the most expensive and labor-intensive parts of drilling is simply moving the equipment. It can take a full 1. Each piece of machinery must also be well-maintained and serviced after use to keep it in top-condition. If a property is exceptionally rocky or the bedrock is relatively high, some rocks may need to be drilled around, drilled through, or removed entirely. Pipe Depth. Drilling costs increase with each foot drilled. If ground loops are not properly sized, the geothermal system may not be able to adequately absorb or reject heat.
This means the home will use more energy than it otherwise would to reach the temperature on your thermostat. A drilling crew usually includes a master driller and 1 to 2 helpers. Installing a vertical ground loop requires an assortment of materials like piping, grout, heat transfer fluid, bentonite clay, bore headers, drill bits, and more.
Geothermal Incentives For Homeowners in the Northeast. Federal Tax Credit. NY State Incentive. CT State Incentive. MA State Incentive. How do the incentives work?
Select your location below:. New York NY. Connecticut CT. Massachusetts MA. Each utility has a unique incentive. That means a homeowner who uses Con Edison will qualify for a different incentive amount than a homeowner who uses National Grid. Here's what you're entitled to as a Long Island homeowner.
System Size. Split System 5T. Packaged Unit 4T. Packaged Unit 5T. Packaged Unit 6T. Here's what you're entitled to as a Connecticut homeowner. Heating Fuel. Electric Resistance. Here's what you're entitled to as a Massachusetts homeowner. Primary Fuel Type. The credit does not apply to equipment used primarily for pool or hot tub heating.
It also does not apply to installation in rental homes. In turn, you use more electricity. It turns off and on more quickly, and this can leave cold or hot spots in your home. This allows it to run at the correct speed for the required temperature.
This makes it very efficient while ensuring it produces more even temperatures throughout your home. It may not save enough on energy bills if you live in very cold or very hot planting zones to offset the higher geothermal costs for installation. You can get closed and open loop systems with closed-loop being the most common choice.
The most common setups include:. This system will operate in one of three basic methods. With a closed loop system, water or refrigerant gets continuously circulated throughout your system.
This gives you more installation options. This is one of the most common options available if you have enough space. However, it needs a lot of space. However, the bigger the system is, the bigger the area you need, and you have to go deeper the colder your climate is. The coils take energy from the water, and this system uses refrigerant. Not every pond, lake, or property will work with this particular system, so you want to double-check with your local zoning offices to see if your property is a good fit.
This system will take up less space compared to horizontal systems, but the coils will go much deeper into the earth. The contractors will usually dig several wells before sinking the coils to the bottom of the wells to connect them. They work for smaller yards because they get installed in smaller footprints. However, the drilling required for the wells will drive up your total geothermal costs.
It uses water directly to help cool or heat your home. It takes water in, cools or heats it, and then dumps it back out. So, this system is illegal in some areas.
Labor is a large part of your final project costs. Heat pumps come in several sizes, just like any other HVAC system. They usually get sold in tons, and a one-ton system is around 12, BTUs. There are several factors that help decide what size system you need, and one of the biggest factors is where you live.
