Home heating is the largest energy expense for most U.S. homeowners and accounts for nearly 30% of energy used in the nation's residential buildings. Millions of homeowners in colder regions of the country do not have natural gas available, leaving furnaces to be fueled with heating oil, propane, or electricity. This can often result in higher heating bills for homeowners. However, soon, these 2.6 million homeowners living in cold climates will have another, efficient home heating option. Oak Ridge National Laboratory (ORNL), collaborating with Emerson Climate Technologies, developed a prototype for an air-source heat pump for the colder regions of the country--one that heats better and uses significantly less energy.
