Scope for the Negotiation

Standard Scope Proposals
• Efficiency Advocates Caucus – Hold circulators (and dedicated-purpose pool pumps) for additional
ASRAC-approved Negotiation • Include schedule in term sheet for this working group
– Target date is term sheet for 2nd negotiation by end of this year (subject DOE capacity) – begin immediately following this negotiation
• Working group recommendation to ASRAC
• HI Proposal – Adopt Lot 11 (ESCC, ESFM, IL, RS-V, VT-S) – Do not adopt any Lot 11+ (DS, AS, RS-H, VT, immersible)
• Savings in Lot 11+ are not great and costs are very high and time consuming • % of DS pumps in market are declining because consumers are switching to
larger end suction pumps that cost less
• EEI Proposal – Move VT from not covered to covered
• PROPOSAL FOR VOTE: Include VT as covered in this rulemaking. – Vote results: 5 Yes 8 No 3 abstain (3/26/14)

Sanitary Pumps “Hygienic” or “sanitary” pumps are typically used in food processing and pharmaceutical applications. They are designed with special parameters, specific materials and surface finish to a variety of national and international rules and regulations that will minimize the biological growth inside the pump to protect public health. These design parameters and materials may result in lower efficiencies than for standard water pumps. Certifications for hygienic or sanitary products include, but are not limited to: 3-A Sanitary Standards EHEDG (European Hygienic Equipment Design Group) recommendations QHD (Qualified Hygienic Design)
Definitions to be worked on later (and DOE will review prior to finalization).
PROPOSAL FOR VOTE: This rulemaking will explicitly exclude sanitary pumps, listed as ‘OK – 3/26/2014’
in the table above.
• Vote results: 16 yes (unanimous 3/26/14)

Increases in circulator MSP will result from two distinct sources:
1. Increased motor cost
• Switching from Permanent Split Capacitor (PSC) wet-rotor to ECM will increase purchased-parts and/or labor costs
• Motors are either manufactured in-house, or built-to-spec out of house. Circulator motors cannot be bought off-the-shelf.
• There is no publically available data on PSC wet-rotor motor cost, and we have not received enough data to aggregate
- In a rulemaking, we may be able to reverse engineer motor costs
- For this exercise, we extrapolate from off-the-shelf motors in the CRE rulemaking
2. Increased manufacturer markup to cover manufacturer redesign and conversion costs.
Incremental Costs for Circulators
18
CRE rule looked at off-the-shelf PSC and ECM motor costs for shaft powers ranging from 6 to 16 Watts.
A small, 1/25 HP circulator pump requires a shaft wattage of 29.8 Watts.
• Approximately 90 Watts of draw for a PSC and 45 Watts for an ECM.
The CRE cost curves can be extrapolated to 29.8 Watts, with the results:
• PSC: $15.77 • ECM: $30.87 • Ratio of ECM to PSC cost: 2.0
Based on manufacturer provided data, the shipments-weighted-average cost for a 3-Speed, Wet Rotor, PSC Circulator motor is:
• PSC (wet-rotor): $29.50
Assuming the 2.0 cost ratio holds: • ECM (wet-rotor): $59.00
Approximate Incremental Costs of $29.50
