Commercial Package Boilers

Department of Energy

The Department of Energy (DOE) has regulated the energy efficiency level of commercial packaged boilers since 1994. Commercial packaged boilers are low pressure packaged boilers that supply steam or hot water for buildings, primarily for heating and space conditioning applications. Commercial packaged boilers are industrial equipment with a maximum rated input capacity of 300,000 Btu/h or more.

    Energy Conservation Standards for Commercial Packaged Boilers

    Summary: EPCA, as amended by AEMTCA, requires the Secretary to determine whether updating the statutory energy conservation standards for commercial packaged boilers is technically feasible and economically justified. If justified, the Secretary will issue amended energy conservation standards for such equipment.

    Type of Regulation: Energy Conservation Standard

    N/A

    Standard Level

    These standards cover gas-fired and oil-fired packaged low-pressure steam and hot water boilers that are industrial equipment with maximum rated input capacities of 300,000 Btu/h or more, which are disturbed in commerce for: (1) heating or space conditioning in buildings or (2) for service water heating in buildings, but do not meet the definition of "hot water supply boiler."

    Commercial packaged boilers manufactured and distributed in commerce, as defined by 10 CFR 431.82, on or after March 2, 2012, must meet the energy conservation standards specified in the Code of Federal Regulations, 10 CFR 431.87. These levels are shown in Table 1 below. In addition, DOE established future updates to the energy conservation standards for two classes of commercial packaged boilers, which are shown in Table 2. The future energy conservation standards are applicable starting on March 2, 2022.

    Each commercial packaged boiler listed in Table 2 and manufactured on or after the effective date listed must meet the applicable energy conservation standard in Table 2.
