This fluctuation allows the home to efficiently maintain a steady, even temperature. Two-stage heat pumps typically cost more than single-stage heat pumps but less than variable-stage heat pumps while achieving moderate to excellent efficiency levels. As a result, these units rarely shut off while maintaining a consistent temperature and excellent efficiency.
Variable stage heat pumps cost more than either single or two-stage heat pumps but can experience higher repair costs due to their complexity and only average durability. Homes with larger heating and cooling loads require larger heat pumps -- and sometimes even more than one. The larger the heat pump, the greater the cost.
A water-to-air heat pump is suitable for homes that use ductwork for heating or cooling, whereas a water-to-water heat pump is compatible with homes that use water-based heat distribution systems like radiators or in-floor radiant heating. Water-to-water distribution systems are generally more complicated and thus more expensive.
Older homes generally have distribution systems that are designed to deliver heat with the high temperature water that you get from a boiler F. Water-to-water geothermal systems can only deliver up to about F water temperatures, which usually means the old distribution system radiators, etc need to be replaced or abandoned altogether.
These costs quickly add up. The Dandelion Heat Pump is a water-to-air pump. Homes with multiple zones are divided into areas that each have their own individual temperature control. Duct zoning provides more granular temperature control in sections of the home e.
Installing a geothermal heat pump is often part of 'electrifying' a home. Electrifying a home increases the total amount of electrical power that is pulled, and this can sometimes strain the main line or panel that handles the home's power. This increase is sometimes minor and relatively common, so the cost will be lower.
Some homes require a significant increase, however, which comes at a cost-premium. A horizontal ground loop is installed over a wide area of ground and requires enough space to dig trenches hundreds of feet long and feet deep. If a typical 2, sq. This cost includes only materials, labor, equipment, and supplies and is not the same as the price paid by the customer. A vertical ground loop is installed in one or more boreholes about to feet deep in the ground. If a 2, sq. The most appropriate loop type for your home primarily depends on the amount of land available and whether or not you have a pond on your property!
All three loop types can be equally efficient when installed properly, but the cost can vary widely due to the factors explored below. The ground loop size is based on the geothermal heat pump size, the soil conditions, and the overall climate. Moist soil will usually transfer heat more efficiently than dry soil. Heat transfer increases with stable, constant temperatures. Temperatures are more consistent in deep ground and less consistent in shallow ground. 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.

Always Improving Automatic software updates so your system will get even smarter over time. It can also be installed in a newly built structure. The specific size of a geothermal heat pump, as well as the size of the ground loop required, is dependent on the cooling and heating requirements in a home. Essentially, the capacity of geothermal systems is usually measured in tons.
For an average home, a 3-ton installation will be ideal. However, it is crucial to mention that apart from the size of the home, there are other factors that determine the correct size of geothermal heat pumps for a home. 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. 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.
Compared to geothermal costs of a decade ago, the pricing structure is becoming more competitive, thanks to the fact that there are more manufacturers offering ground source heat pumps, and more experienced and efficient installers. Though geothermal is an ideal way to heat and cool a home, there are a few factors to consider when deciding if the time is right for a ground source heat pump system in your home.
According to the Environmental Protection Agency, geothermal ground source heat pump systems are one of the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available. The longer you intend to stay in your current home, the more cost-effective a geothermal system is in the long run. If you have the ideal location for setup, your upfront cost will be lower.
Having room in your yard for a horizontal loop system, is the best option for lowering costs. Plus, if a ground source system can be fitted with your current ductwork or hydronic system with little or no modification, your costs will be lower than if major changes must be made. The more extreme heat or cold in your climate, the faster you will recoup your investment through lower energy costs. Living in climate extremes apparently can have its perks.
