51,000 U.S.-Made Geothermal Heat Pumps Shipped

More than 51,000 U.S.-made geothermal heat pumps were shipped during 1996, according to the Energy Information Administration of the U.S. Department of Energy. Of these, 49% were shipments to the South, 23% to the Midwest, 12% to the Northeast, 7% to the West, and 8% were exported. Somewhat surprisingly, shipments have been fairly flat during the 1994 through 1996 period, the only years for which there is data, and shipments actually dropped 5% from 1995 to 1996, from 54,425 units to 51,520. The agency reported that there are approximately 50 domestic manufacturers of geothermal heat pumps.
