Increases in circulator MSP will result from two distinct 

1. Increased motor cost

• Switching from Permanent Split Capacitor (PSC) wet‐roto

will increase purchased‐parts and/or labor costs

• Motors are either manufactured in‐house, or built‐to‐spe

house. Circulator motors cannot be bought off‐the‐shelf.

• There is no publically available data on PSC wet‐rotor mo

we have not received enough data to aggregate

- In a rulemaking, we may be able to reverse engineer motor 

- For this exercise, we extrapolate from off‐the‐shelf motors 

rulemaking

2. Increased manufacturer markup to cover manufact

redesign and conversion costs.

Incremental Costs for Circulators
18

 CRE rule looked at off‐the‐shelf PSC and ECM motor costs for sh

ranging from 6 to 16 Watts.

 A small, 1/25 HP circulator pump requires a shaft wattage of 29

• 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 

• 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

Baseline Motors: Cost Extrapolation
