Recent and Ongoing Activities

DOE has published a Federal Register Final Rule establishing definitions, a test procedure, sampling and rating requirements, and enforcement provisions for circulator pumps. Currently, circulator pumps are not subject to DOE test procedures or energy conservation standards. DOE is adopting a test procedure for measuring the circulator energy index for circulator pumps. The test method references the relevant industry test standard. The definitions and test procedures are based on the recommendations of the Circulator Pump Working Group, which was established under the Appliance Standards Rulemaking Federal Advisory Committee.

  • The effective date of this rule is October 19, 2022.
  • Compliance with the final rule will be mandatory for representations of head, flow rate, driver power input, circulator energy rating, and circulator energy index made on or after March 20, 2023.

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.
