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. To get a rough estimate, take the square footage of your home and multiply it by the number of BTUs required by your climate zone:. Furnaces get larger in colder climates, but heat pumps only have to get big enough to handle your needs when the temperature spikes.
When you buy this system, the area where you want to install it will impact the type of system you can get. If you have an area that is easy to get to and has room for the entire system to fit into one space, including a compressor and two heat exchangers, get a packaged unit. This system needs to be welded or connected on-site, and this can increase your geothermal costs.
However, it also gives you more flexibility where you install the various components. The biggest geothermal costs come because of the installation process. Every HVAC system comes with varying efficiency degrees.
This degree refers to how much energy they use to produce heat or cool a room. One is the cooling rating and one is the heating rating. The COP Coefficient of Performance for heating measures how well the unit can use energy to heat your house. Geothermal heat pumps come with a COP rating of three to five. This is a lot more efficient than other systems that come with a COP of one or two in high-efficiency systems.
Geothermal ground loops are installed using either drilling or trenching equipment based on the loop type and depth. Because horizontal ground loops are long but shallow, installers use a backhoe or a chain trencher to dig them.
Alternatively, vertical ground loops require a drill rig to drill one or more holes several hundred feet deep as well as grout machine to fill in these holes. Drilling is almost always more expensive than trenching. For many homeowners, vertical ground loops are the best and only option due to space constraints and local geography. Updated October Please note the incentive landscape is rapidly changing and may have shifted by the time you come across this resource.
What Federal, State, and Utility incentives apply to you as a homeowner? In the form of personal tax credits, these incentives save Dandelion customers thousands of dollars. State-level incentives depend on the location you reside in and which utility company you have. Details are listed below. The rebate program requires a pre-inspection and post-inspection step at the customer's home.
Dandelion has built this into the installation timeline to ensure all rebate requirements are met. Below is a list of the PSEG rebate based on system size:. Both Eversource and United Illuminating offer geothermal heat pump incentives via the Energize Connecticut program The following municipal utilities are not part of the Energize Connecticut program; Groton, Bozrah, Norwalk, Wallingford, and Norwich.
See the table below for an example of what an average sized home that needs a 5 ton geothermal heat pump system would qualify for in Connecticut. Geothermal systems are also exempt from state sales tax. However, homeowners cannot take advantage of both. Unfortunately, homeowners who use natural gas to heat their homes are not eligible for a Mass Save rebate at this time.
Dandelion offers homeowners state of the art geothermal heating and cooling at an affordable price. The Dandelion Geothermal system provides home heating, central air conditioning and hot water at over four times the efficiency of any furnace on the market. Experienced 1 New York residential geothermal installer by volume in and Total Integration Our energy consultants work directly with our site survey and design teams to integrate load calculations, ground loop layouts, and other parts of the design process.
That means that by using wifi and secure cloud storage, we collect data about how every part of the system is operating and make recommendations so it can operate even better.
Always Improving Automatic software updates so your system will get even smarter over time. This price can increase based on additional complexity like ductwork modifications, electrical upgrades, zoning, bedrock removal, or if multiple heat pumps are needed. Here is an example of a typical 2, square foot home in Cortlandt, NY with fuel oil heating and central air conditioning versus a Dandelion Home Geothermal Heating and Cooling System.
Geothermal Pricing Guide. Geothermal System Permit Costs. Indoor Portion Costs. The actual heat pump price is scaled up or down based on the variables below. A heat exchanger that interacts with the outdoor ground loop. A compressor. Heat Pump Compressor Type There are 3 types of heat pump compressors : single-stage , two-stage , and variable-stage.
A variable-stage heat pump can vary its levels of intensity incrementally. Multiple Zones. Electrical Upgrades Installing a geothermal heat pump is often part of 'electrifying' a home. Outdoor Portion Costs. Dense rock and clay can hold and transfer more heat than sand.
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. When selecting and installing a geothermal heat pump, consider the heating and cooling efficiency, the economics of the system, and your site's characteristics. Be sure to find a qualified installer. The heating efficiency of ground-source and water-source heat pumps is indicated by their coefficient of performance COP , which is the ratio of heat provided in Btu per Btu of energy input.
Their cooling efficiency is indicated by the Energy Efficiency Ratio EER , which is the ratio of the heat removed in Btu per hour to the electricity required in watts to run the unit. Many GHPs carry the U.
These geothermal heating and cooling units installed in the basement of a new home are tied to a complex array of underground coils to keep indoor temperatures comfortable. Although the purchase and installation cost of a residential GHP system is often higher than that of other heating and cooling systems, properly sized and installed GHPs deliver more energy per unit consumed than conventional systems. For further savings, GHPs equipped with a device called a "desuperheater" can heat household water.
In the summer cooling period, the heat removed from the house is used to heat the water for free. Depending on factors such as climate, soil conditions, the system features you choose, and available financing and incentives, you may recoup your initial investment in a few years through lower utility bills.
And -- when included in a mortgage -- your investment in a GHP may produce a positive cash flow from the beginning. It may also be possible to include the purchase of a GHP system in an "energy-efficient mortgage" that would cover this and other energy-saving improvements to the home. Banks and mortgage companies can provide more information on these loans.
There are also special financing and incentives available to help offset the cost of adding a GHP to your home. These provisions are available from federal , state, and local governments; power providers; and banks or mortgage companies that offer energy-efficient mortgage loans for energy-saving home improvements. Be sure the system you're interested in qualifies for available incentives before you make your final purchase. Shallow ground temperatures are relatively constant throughout the United States, so geothermal heat pumps GHPs can be effectively used almost anywhere.
