DOE to Establish Circulator Pump Efficiency Standards
Jan. 16, 2017
Chuck White, VP of Regulatory Affairs
The U.S. Dept. of Energy (DOE) Circulator Pump Working Group concluded its series of negotiations on Nov. 30 to establish efficiency standards for circulator pumps. PHCC Vice President of Regulatory Affairs Chuck White participated as a member of this working group with the five major pump manufacturers, energy advocates and the DOE.
This product class, previously unregulated, has been known to have some pumps with wire to water efficiency levels as low as 15 percent. New technologies have been developed over the last decade offering substantial increases in this efficiency.
The working group has formulated a set of recommendations, to be reviewed by ASRAC (the Appliance Standards and Rulemaking Federal Advisory Committee) and DOE, to establish this new efficiency standard. While DOE does not specify technologies, the agreed-upon standard level would effectively mandate a minimum pump be a fixed curve ECM-type product. All current PSC (permanent split capacitor)-type pumps would be eliminated from the market.
While more work must be done at the DOE to create the final rule and no timeline has been established, it is expected that these efficiency levels would not be in effect earlier than 2021.
