The U.S. Department of Energy (DOE) has issued a pre-publication final rule adopting energy conservation standards for circulator pumps. The Energy Policy and Conservation Act, as amended (“EPCA”), prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including circulator. EPCA also requires the U.S. DOE to periodically review its existing standards to determine whether more stringent standards would be technologically feasible and economically justified, and would result in significant energy savings. In this final rule, DOE is adopting new energy conservation standards for circulator pumps. It has determined that the amended energy conservation standards for this equipment would result in significant conservation of energy, and are technologically feasible and economically justified.

• The effective date of this rule is 75 days after the date of publication in the Federal Register.
• Compliance with the amended standards established for circulator in this final rule is required on and after 4 years after the date of publication in the Federal Register.

For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change.

There are currently no DOE energy conservation standards for circulator pumps.

Representations of energy use or energy efficiency of circulator pumps must be made in accordance with the results of testing pursuant to Appendix D to Subpart Y of 10 CFR Part 431 – Uniform Test Method for the Measurement of Energy Consumption of Circulator Pumps.
