This cost would cover a complete geothermal installation. A 2-ton geothermal heat pump provides 24,000 BTUs, so it's best used in places with a relatively warm climate. In addition, a professionally installed ground-based heat pump can use three to five times the amount of electricity you use to heat your home compared to ovens, which burn as much energy as they generate. With a geothermal heat pump, there is no on-site combustion and, therefore, there are no emissions of carbon dioxide, carbon monoxide, or other greenhouse gases.
The growth in the geothermal heating and cooling market is averaging 12% per year, as the demand for highly efficient air conditioning systems that use sustainable energy continues to increase. Anything greater than an EER of 12 is considered highly efficient, making all geothermal heat pumps highly efficient cooling appliances. We surveyed dozens of geothermal installers and found the average percentage of the total cost consumed by each part of installing a geothermal system. The term distinguishes them from air-source heat pumps or ASHP that collect and discharge heat using outdoor air.
When installing geothermal heating and cooling or any type of HVAC system, you need a thermostat to control when the system is turned on and off. However, installing a geothermal heat pump is so expensive that you may be tempted to forget about it completely. Geothermal systems don't have to work harder due to extreme outdoor air temperatures, as do other heating and cooling systems. With three, four or five residents, they can use a 5-ton heat pump for adequate heating and air conditioning.
Because heat pumps provide both heating and cooling, they have two different levels of efficiency, one for each. Until 2024, a federal tax credit exists to help cover the cost of installing renewable energy systems, such as geothermal heat pumps. This figure is not accurate and does not reflect how much it will cost to install a geothermal heat pump in your home. Geothermal heating and cooling systems are efficient, environmentally friendly, and could save you money in the long run.
However, it is crucial to mention that, in addition to the size of the house, there are other factors that determine the correct size of geothermal heat pumps for a home.
