Data from a 2015 Residential Energy Consumption Survey (RECS) uncover that a infancy of American households use one of 3 forms of apparatus as their categorical source of feverishness during a winter: healthy gas furnaces, electric furnaces, or electric feverishness pumps. The operation of apparatus and fuels, however, varies opposite and within U.S. meridian regions. The use of delegate heating sources, such as unstable electric heaters and fireplaces, serve adds to a opposite ways households devour fuel to stay comfortable in a winter.
Broad ranges in winter temperatures and capabilities of opposite technologies meant that certain heating choices are improved matched to certain climates. Overall, 47% of households rest on healthy gas as their categorical heating fuel, compared with 36% who rest on electricity. Natural gas furnaces are a many common categorical space heating apparatus used in each meridian segment solely a hot-humid segment of a Southeast, where heating needs are reduce and electric furnaces are some-more prevalent. In a mixed-dry/hot-dry meridian segment in a southwestern United States, 15% of homes do not use heating apparatus during all, compared with a inhabitant normal of 4%.
Electric feverishness pumps are befitting to a comparatively amiable winters in hot-humid areas and some mixed-humid areas. Of a 12.1 million households that use electric feverishness pumps, 9.3 million are in these dual regions, that cover many of a Southeast.
The high cost of electric heating in colder climates has mostly singular a use of feverishness pumps and other electric apparatus in those areas. However, advances in feverishness siphon technology, including cold-climate feverishness pumps, have enabled some-more fit electric space heating in areas with reduce winter temperatures. In 2015, 1.3 million households in a cold/very cold meridian segment had electric feverishness pumps, or about 3% of a informal total.
Other fuels, such as essence fuel oil and kerosene, are some-more ordinarily used for space heating in a cold/very cold region, though a use of these fuels continues to decline. In a 2015 RECS survey, 5.9 million homes in a United States reported regulating fuel oil or kerosene as their categorical heating fuel, a 20% decrease from a formula of a 2009 RECS survey.
Nationwide, 37% of U.S. households addition their categorical apparatus with a delegate source of heat. Almost half of these households use unstable electric heaters, a many common delegate heating choice in each meridian region. Fireplaces regulating healthy gas or timber are a subsequent many renouned choices. Some households use furnaces or feverishness pumps as their fill-in heating source, apparatus forms that are some-more ordinarily used as a categorical source of heat.
When deliberation both categorical and delegate heating apparatus and fuels, U.S. households select a opposite set of heating scenarios. Among a 5,687 households that were surveyed in a 2015 RECS, EIA celebrated over 150 singular combinations of heating apparatus and fuels.
