Geothermal heat pumps make use of the earth's temperature in heating and cooling spaces. This type of heating and cooling system is also known as ground source heat pumps, and the geothermal system is known to be energy efficient, using sustainable resources to power up the unit. The ground source heat pump have various factors you need to consider.

Factors to Consider Before Purchasing a Geothermal Heat Pump

Budget

Geothermal heat pump systems come with a hefty price tag. A geothermal heat pump will cost between $12,000 to $30,000 just for the unit, and installation costs can bring the price up even higher. The unit needs vast land requirements as well, and some properties may not have available space to install the unit.

Energy Consumption

Geothermal heat pumps are known for their energy efficiency. The unit makes use of the constant temperature of the earth to heat or cool spaces. They hardly produce any emissions, and can save up to 80% of the energy used in operating central air conditioners and other cooling systems. They operate on a renewable resource that is available year-round as well.

Space Requirements

Geothermal units require land space, and cannot be installed in apartment units or condominium units without sufficient land space. Since these units are installed underground, most geothermal heat pumps are installed for landed properties. 

Cooling Power

The geothermal heat pump makes for an efficient cooling system, rapidly cooling or heating up spaces as needed. Many units can also provide hot water by heating up the water source. Yet, they use 25%-80% less energy than conventional cooling and heating systems.

Maintenance

Despite their complex structure, geothermal heat pumps are low maintenance. They can last for at least 20 years, up to 50 years with proper care. The majority of geothermal heat pump systems are sheltered indoors or underground, keeping them away from external factors that can cause damages as well as regular wear and tear.

While these are low maintenance, geothermal heat pump systems still require a level of maintenance from time to time. However, it will be difficult for homeowners to find an aircon service company that has experience handling a geothermal system.

Geothermal Heat Pump Installation Process

Geothermal systems are installed underground, often underneath the house or in the backyard. They are typically installed professionally, and may incur high installation costs as geothermal units will need to be settled underground with a support frame to prevent heavy pressure from damaging your machine.

A single geothermal unit can cool down or warm up an entire house, and its main components are hidden from plain sight. As water circulates around the unit, homeowners will need to ensure their pipes are properly fitted, and are not susceptible to leaks or breaks. Hence, the vast majority of homeowners choose to have their units installed professionally.
