Additional Details
A ground source heat pump takes advantage of the earth’s constant temperature to provide highly efficient heating and cooling. In the winter, fluid circulating in underground pipes carries the earth’s heat to your home, where it is then concentrated to provide heating. In the summer, the process is reversed and heat from your home is carried back to the earth through the pipes to provide cooling.
Ground source heat pump systems have three main parts:
- A closed loop, which circulates fluid through an underground field. The loop is enclosed in vertical and/or horizontal trenches.
- Single or multiple pumps, fans, and compressors that provide heating and cooling.
- A distribution system, typically ductwork, that carries air throughout the home to maintain an even temperature.
According to studies, ENERGY STAR® certified ground source heat pumps can reduce energy costs by 20 to 70 percent. A ground source heat pump is a reliable, low-maintenance, and environmentally friendly heating and cooling choice. It operates safely and quietly, with no combustion, direct emissions, or exposed outdoor equipment, such as a fuel tank. Because it is mechanically simple and all exterior equipment is below ground, protected from the weather, maintenance costs are often lower than other heating and cooling systems.
Eversource and UI residential electric service customers are eligible for incentives for the installation of a ground source heat pump closed loop or direct expansion, packaged or matched coil/split* including water to water-designed types up to six tons per unit.
Ground source heat pump equipment must be a closed loop or direct expansion type and ENERGY STAR® certified in order to be eligible for a rebate.
A list of ENERGY STAR certified ground source (geothermal) heat pump equipment can be found on the ENERGY STAR website. You can also refer to the rebate application for equipment eligibility requirements.
Incentives for qualifying units:
Existing homes heating with electric or natural gas: $750 per AHRI-rated cooling ton for successfully commissioned geothermal systems with a maximum incentive amount of $15,000 per home.
Existing homes heating with oil or propane: $1,500 per ton with a maximum incentive amount of up to $15,000 per home.
The average Connecticut home is eligible to receive more than $7,500 when upgrading to ground source heat pumps.
*Multiple sections and fans must be AHRI matched.
If you are a Connecticut resident and are not served by one of the utilities listed above, please visit your municipal utility’s website to see what programs are available to you.
