Definition Of Geothermal Heat Pump
A geothermal heat pump (GHP) is a type of energy-efficient heating and cooling system that harnesses the steady temperature below the ground’s surface to warm or cool indoor air.
Working Of Geothermal Heat Pump
- The system operates by using long loops of plastic buried in the ground, which act like an underground furnace.
- In the summertime, hot air from inside your home is transferred through this loop, where it’s cooled off by the cooler temps beneath before being pumped back inside.
- GHPs are powered by electricity but tap natural resources for their operation.
- So instead of burning fuel to create heat they use stored thermal energy as a reliable source of power.
Brief Overview Of Geothermal Heat Pump Installation
Installing a geothermal heat pump is an involved process that requires expertise and attention to detail.
To begin, the property must be evaluated to ensure it’s suitable for a geothermal system factors like soil type, ground composition, surface features, and other nearby infrastructure can affect the installation of the loop field which will extract energy from the ground or well site.
Once the evaluation is complete and all set up requirements have been met, holes are drilled into the ground where pipes are placed in either vertical or horizontal loops depending on site conditions.
Excavation around these wells may also be required as part of the installation in order to properly level and secure them in place.
Finally, specialized equipment including pumps and indoor units are integrated with existing home systems before connecting to A/C components which circulate hot and cold air throughout living areas via ductwork.
Factors Affecting Geothermal Heat Pump Installation Cost
Several factors must be taken into consideration when estimating the cost of geothermal heat pump installation, including Type of System, Property Size and Layout, Soil and Geology Conditions, Accessibility and Installation Complexity.
Type Of System
Geothermal heat pumps can be divided into two main categories: closed-loop systems and open-loop systems.
Closed-loop systems are composed of pipes buried horizontally or vertically beneath the earth’s surface, with water or an antifreeze solution running through it to extract energy from the earth.
Whereas open-loop systems involve pumping natural groundwater from an aquifer or well to transfer its geothermal energy as a source for heating and cooling.
Generally speaking, closed-loop geothermal heat pump installation costs more upfront than open loop due to extra labor involved in drilling loops deep into the ground.
Depending on soil conditions and local regulations, horizontal loops may require additional components like manifold boxes during their construction process.
Property Size And Layout
The size of the property will have an effect on the cost of geothermal heat pump installation.
A smaller home means a shorter loop field is necessary, and therefore may lead to a lower cost for installation compared to a larger home that would require more equipment and extra digging.
If there are multiple levels within the house, then additional costs may be incurred due to needing extra brackets or support for either installing equipment at different heights or because access points were not factored into initial costing calculations.
The layout of your property can also affect the price as certain obstacles such as existing buildings, driveways, pipes or rocks need special consideration prior to designing your system so any added complexities need more time and materials making it more costly for installation overall.
Proper system sizing is essential in order to achieve maximum savings from sufficient temperature levels throughout the year which helps keep energy bills down.
Soil And Geology Conditions
- The soil and geology conditions on the property can play a major role in the cost of geothermal heat pump installation.
- Heavily wooded areas, for example, will require more specialized equipment for drilling and excavating, leading to increased labor costs which can affect the overall expense of installing a GHP system.
- The type of soil also affects efficiency; clays or silts tend to be better conductors than sand and some soils might not provide adequate conductivity at all.
- Poorly performing conduits due to uneven or shallow placement could reduce energy efficiency by up to 50%.
Accessibility And Installation Complexity
Accessibility and installation complexity can play a major role in overall geothermal heat pump installation cost.
Factors that affect accessibility include the property layout, existing infrastructure, and soil or geological conditions.
For example, if there are large rock formations or unusual terrain which requires extra effort to install a loop system for the geothermal heating system then this will increase labor costs and shorten the lifespan of the unit due to inadequate ground cover.
Other factors such as accessibility to plumbing fixtures for water line connection will also impact cost significantly depending on how deep underground they are located throughout your property
Trenching costs can quickly add up when running these lines long distances from one end of your home to another such as between an outdoor condenser and interior heat pump units.
