Geothermal Heat Pumps for Consumers

A new ENERGY STAR specification for geothermal heat pumps (114KB) went into effect on December 1, 2009. The new specification allows water-to-water GHPs to immediately be eligible to qualify for the label. On average, ENERGY STAR qualified products covered under this new specification will be over 45 percent more energy efficient than standard options.

Anticipating advances in technology in the coming years, EPA has set more stringent efficiency requirements to ensure that ENERGY STAR continues to represent top performers in this category.

New requirements for water-to-air and direct geoexchange GHP models will take effect on January 1, 2011. Even more stringent levels will go into effect for water-to-water and water-to-air models on January 1, 2012.

As of December 1, 2009 homeowners who install geothermal heat pumps with the ENERGY STAR are eligible for a 30 percent federal tax credit. Learn more.

Geothermal heat pumps are similar to ordinary heat pumps, but use the ground instead of outside air to provide heating, air conditioning and, in most cases, hot water. Because they use the earth’s natural heat, they are among the most efficient and comfortable heating and cooling technologies currently available.

Remember, saving energy prevents pollution. By choosing ENERGY STAR and taking steps to optimize the performance of your heating and cooling equipment, you are helping to prevent global warming and promoting cleaner air while enhancing the comfort of your home.

Though these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills.

When buying new equipment, sizing and installation are as important as product quality.

You can get better heating and cooling performance at home with ENERGY STAR home sealing (insulation and air sealing) and duct sealing.

Consider regular maintenance to maintain your heating and cooling system performance.
