Scope Discussion ‐ Circulator Energy Use Shipments Data

• HI: 1.7 million [0‐3 HP, wet and dry]

- likely includes some small pumps that are not circulators

• Advocates: 2 million [0‐1/4 HP]• DOE: 1.5 million [0‐3 HP, wet only]

 Estimated Annual Operating Hours

• HI: 2160 [Provided]

 Average motor draw

• HI: 1/10 HP (78W) [Calculated]

- Does not seem realistic. 78W is less than the operating electric power dr

common “1/25 HP” nameplate circulators. HI survey collected data on 1/circulators.

• Other: 2/10 HP (155W)

- Using the assumption that HI collected nameplate HP and applying 50% e

 Average Load

• Assume power draw is constant across loads

 Annual Energy Use

• HI: 0.285 TWh [Provided]

• Advocates: 1.0 TWh [Calculated]

• Other: 0.57 TWh

- [1.7 mil, 2160 hours, 1/10 HP hydraulic, 50% motor/pump eff]

• Estimated potential energy savings from switching to ECM (cons

• Estimated potential energy savings accounting for variable load

 Other data for circulators:

• Incremental cost of ECM vs AC Induction• Aggregate industry conversion cost• Availability of ECMs

• Testing costs and issues

 The objective of a metric

• Be objectively measurable• Allow for comparability across models

• Focus on energy use or efficiency of the equipment being measur

• Limit test burden

• Inform purchasing decisions

 DOE limitations on setting metric

• Must describe energy efficiency or energy use for a covered prod

• Must be a single descriptor
