The popularity of geothermal heat pumps continues to grow. These days, you can read about them in just about every issue of every HVAC trade publication. They offer a way to provide low-cost heating as well as cooling.
An increasing number of state energy offices are formally recognizing geothermal heat pumps as renewable energy sources. This allows them to qualify for various financial incentive programs. Some electric utilities also are offering incentive programs to encourage their use. The federal government recognizes geothermal heat pumps that meet Energy Star requirements as eligible for a 30% Residential Renewable Energy Tax Credit.
