Energy Conservation Program: Energy Conservation Standards for Unfired Hot Water Storage Tanks
The Energy Policy and Conservation Act, as amended (EPCA), prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including unfired hot water storage tanks (UFHWSTs). EPCA also requires the U.S. Department of Energy (DOE or the Department) to periodically determine whether more-stringent, amended standards would result in significant additional conservation of energy, be technologically feasible, and be economically justified. After carefully considering the available market and technical information for this equipment, DOE has tentatively concluded in this document that it lacks clear and convincing evidence that more-stringent standards for UFHWSTs would save a significant additional amount of energy and would be economically justified. As such, DOE has initially determined that energy conservation standards for UFHWSTs do not need to be amended. DOE requests comment on this notification of proposed determination (NOPD), as well as the associated analyses and results.
