High-end geothermal systems on larger homes could potentially cost a homeowner upward of $80,000.
If you’re like me, those higher costs could drive you away from the installation of geothermal energy. With that being said, the long-term benefits of a geothermal system will save you money over time on your electric bill. That’s why we want to explain all of the costs and benefits involved with geothermal energy so you can decide what is best for your home.
How much does geothermal installation cost?
The cost of geothermal system installation for homeowners typically falls within the range of $8,000 to $25,000 on average. However, it’s important to consider various factors that can influence the final cost, such as the size of the geothermal system, the type of loop system, and the specific heat pump chosen. Additionally, local geology, property accessibility, and the choice of installation company can also impact the overall cost of the geothermal system installation. It is recommended to assess these factors and obtain personalized quotes from reputable installers to get a more accurate estimate for your specific circumstances.
Specifically, the different types of systems can change the price significantly for your geothermal energy system.
- Horizontal loop system: $15,000 to $30,000
- Vertical loop system: $25,000 to $40,000
- Open loop system: $10,000 to $30,000
- Closed loop system: $25,000 and $30,000
For the installation of a geothermal heating system, you also have to consider the renovations needed in your home to accommodate it. Such as, the ductwork in your home might require rerouting, repairing, or building brand new which could add on up to $5000 in costs.
How much will a geothermal system cost to operate?
One of the best parts of the costs of geothermal systems is that once they’re installed, you start to see those benefits. Installing a geothermal system typically results in significant savings on heating fuel bills for homeowners, while moderately increasing their electrical bills. This trade-off leads to an overall reduction in monthly energy expenses. The extent of the savings will depend on factors such as the type of fuel used by your previous furnace and your specific heating requirements. In many cases, these accumulated savings can amount to thousands of dollars over the lifespan of your geothermal system, making it a cost-effective and financially beneficial investment.
What is the geothermal heating cost per month?
The operational cost of a properly sized geothermal heating system typically ranges from $100 to $200 per month in electricity expenses. It’s important to note that during extreme temperatures when backup heaters are required to supplement the geothermal system, the average electric bill may increase. Additionally, in cases where geothermal lines freeze, there may be added costs associated with running backup heating systems. These backup heaters can be up to twice as expensive to operate compared to the geothermal system alone. It’s advisable to ensure proper system sizing and maintenance to maximize energy efficiency and minimize potential additional costs.
How much does geothermal energy cost per year?
Geothermal power plants, when running at 90% availability, spend around one to three cents per kilowatt-hour. Even newer power plants that charge a bit higher still only cost around $0.05 per kWh. Experts state that with a geothermal system, you can expect a 30% to 70% reduction in your annual utility bill for heating, and 20% to 50% for cooling. Moreover, a geothermal pump with a desuperheater system can reduce water heating costs by 50%. Thus, while the per kWh cost might be slightly higher for geothermal energy, the overall savings in utility bills make it a more cost-effective choice in the long run.
