A geothermal HVAC system is usually worth the cost because it can last for many decades and is incredibly reliable. It uses much less electricity to operate than systems with coal and other fossil fuels, so many homeowners are happy to pay more for the initial installation. The system is installed using either drilling or trenching equipment, depending on the system type. Horizontal systems require trenching, while vertical systems require drilling. Keep in mind that installation is very disruptive to lawns and landscaping. The heavy equipment must be able to reach the site and may dig up more landscaping than the actual installation.
While every brand and model is a bit different, a homeowner can expect to pay more for a pump with a higher EER compared to one with a lower ratio. To maximize geothermal savings, it’s important to minimize the use of AUX Heat. AUX Heat is a normal part of heat pump systems and necessary at times, but it uses much more electricity than the other heating stages. Changes in room temperature or thermostat set points greater than 5°F are the most common trigger for activating AUX Heat. This practice is detrimental, however, when operating a geothermal system. As a result, thermostat setback forces the geothermal system to frequently rely on expensive supplemental systems, unintentionally and ironically increasing the average cost of operation.
Geothermal heating rebates, tax credits, and financing
So the main cost of geothermal is almost exclusively the installation. However, ground loop repairs, though rare, they can be costly—especially for vertical systems as any repairs require more expensive excavation. Direct use geothermal systems are exactly like what they sound. These systems pump naturally heated groundwater from local sources either directly into your home for things like space heating or water heating. They can also be set to cycle through a heat transfer pump just like a traditional ground source heat pump.
For homeowners still on the fence about a geothermal system, the following advantages may offer clarification and encouragement. Every geothermal system installation is unique, and every contractor’s experience is unique as well. Since geothermal heating and cooling are relatively new compared to other options, there can be exceptionally high demand for experienced contractors.
Geothermal Heating and Cooling Cost 2022: Pros & Cons, Comparisons
Horizontal loops systemVertical loop systems are installed where horizontal trenches aren’t possible due to a lack of space. A series of wells are dug, and the pipe loops are installed in the wells. The size of your home and its location, available land, the type of soil, local climate, condition and usability of current duct work, and the type of heat pump you choose will impact the overall cost. This price can increase based on additional complexity like ductwork modifications, electrical upgrades, zoning, bedrock removal, or if multiple heat pumps are needed. Unlike traditional heating systems, Dandelion’s package heat pump has remote monitoring capabilities at no additional cost. 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.
You may need to pay the cost to upgrade your ductwork to accommodate larger systems. Upgrading your ductwork costs from $1,500 to $7,000 for this project. The price of your geothermal installation varies depending on several factors.
Geothermal Heat Pump Installation Cost Breakdown
This programmable device makes it easy to control the temperature inside your home, with an average cost of around $200 to $500 for a smart thermostat with built-in Wi-Fi. That means for every 1 unit of energy used to power your geothermal system, 4 units of heat energy are supplied to your home. Energy is not created as part of this process - when 1 unit of electricity is consumed to deliver 4, it means that 3 units of energy are absorbed from the ground. Ground loop depth depends on the home’s heating and cooling load, the amount of rock, and the local climate. 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.
Installing any sort of heating system is best left to a professional. However, installing a geothermal heat pump leaves some room for DIY projects without sacrificing the safety and efficiency of the system. Vertical geothermal systems are drilled deep into the ground.
Geothermal System Cost Comparison vs. Peer HVAC Systems
If you split the pieces into separate boxes and install them in different places in the house, it's called a "split" system. Combustion-based systems like oil-furnaces, however, are unable to reach even 100% efficiency because they always deliver less energy than they consume. Several factors affect soil’s ability to transfer heat including moisture, composition, temperature variation, and density.
Many homeowners can even recoup the cost of installation within a few years through savings on their utility bills, especially if they can reduce the initial installation costs. You can save on installation costs by opting for a horizontal loop, asking about energy-efficient options, and taking advantage of federal and local tax credits. I'm a little confused by your statement that geothermal is not a reasonable alternative for residential use, except in multi-residential or larger, and/or poorly insulated homes. I'm also a little dismayed with the statement that you can "possibly even eliminate all together" by investing more in insulation.
It is possible to remove these excess Green Energy and Staffing costs. Geothermal is now giving me the savings it did when installed. Domestic Geothermal heating systems can be a great way to heat a home, replace a furnace, and are labeled as money savers. And found the average percentage of the total cost that each portion of a geothermal system installation consumes. When it comes to a new geothermal system, working with an experienced and certified geothermal contractor can ensure the system will last as long as possible.
If a home does not currently have any ductwork, adding it can cost between $5,000 to $20,000 or more depending on the home size, ductwork complexity, and other factors. It'll cycle on and off in low speed for the majority of the year, until if gets really cold/hot out and needs to jump to high speed to keep up. It jumps between stages automatically as dictated by the thermostat control. The unit consumes less electricity in low speed , and runs for longer periods of time.
Once the water has been used, it's usually deposited in another well or returned to the water source. Again, these systems are cheaper to install, but significantly less common than the two most popular ground loop systems—horizontal and vertical ground loops. Here's a complete breakdown of the cost to install a geothermal heating and cooling system for any space.
Geothermal heating is also better for the environment because it does not directly use fossil fuels and uses less electricity than other systems. Therefore, it does not contribute as much to greenhouse gasses. It is also safer with no risk of carbon monoxide or gas leaks. You do not need to store additional fuel on your property like oil or propane3.
