Taco 0015e3 ECM High-Efficiency Circulator — Variable Speed with 3 Selectable Modes

Energy-Saving Circulator for Hydronic & Domestic Recirculation Systems

The Taco 0015e3® is a variable-speed, wet-rotor circulator built around an ECM permanent-magnet motor. The energy-efficient successor to the legendary Taco 0015 3-Speed. It uses up to 85% less electricity than equivalent AC permanent-split-capacitor circulators while delivering the same hydronic performance contractors have specified for decades.

Two configurations available:

• 0015e3-2F4 (cast iron, four-bolt flange) — for closed-loop hydronic heating systems zoned with circulators or zone valves.
• 0015e3-SF4 (stainless steel) — NSF/ANSI/CAN 61 & 372 certified for potable applications, including domestic hot water recirculation, plus general open-loop systems.

Key Features of the Taco 0015e3

• ECM permanent-magnet motor: Up to 85% lower electricity consumption versus equivalent AC permanent-split-capacitor circulators (Taco data).
• Variable-speed operation with 3 preset modes: On HIGH, the circulator runs at full speed. On MEDIUM and LOW, the ECM motor varies speed automatically to maintain constant differential pressure as system load changes. No manual adjustment required.
• BIO Barrier® filter (cast iron variant only): Protects internal components from system contaminants such as sediment and pipe scale.
• SureStart®: Automatically purges air on startup and runs up to 100 self-restart attempts (over ~15 minutes) if the rotor sticks, reducing service callbacks.
• Integral Flow Check (IFC®): Prevents gravity flow through the circulator when off, eliminating the need for a separate flow-check valve.
• Double-insulated: No grounding wire required.
• Easy wiring: Dual electrical knockouts and 6" stranded pigtail leads included.
• Quiet wet-rotor design: No exposed shaft seal or coupling.

Taco 0015e3 Circulator Specification

3 Easy Settings for Custom Performance:

• LOW: For 5 ft. head
• MEDIUM: For 10 ft. head
• HIGH: For 18 ft. head

Taco 0015e3 Applications

Suitable for:

• Closed-loop hydronic heating systems (cast iron variant)
• Open-loop systems (stainless steel variant)
• Indoor installation only
• Compatible with water or up to a 50% water/glycol mixture

NOT suitable for:

• Chilled-water systems
• Swimming pool or spa applications
• Outdoor installation
• Cast iron variant on potable lines (use stainless steel 0015e3-SF4 instead)

Choosing the Right Taco Circulator

Cleanflow stocks several Taco circulators in this category. Here's when each makes sense:

• 0015e3 (this product): Choose this for a direct ECM-equivalent replacement of a Taco 0015 3-Speed, 007, 006, or 008 with simple manual mode selection and no app or programming required.
• 0018e: Step up if you want Bluetooth/app control and infinitely variable speed adjustment.
• 0026e: Step up for higher head/flow commercial applications requiring 5 selectable modes.

Direct ECM Upgrade for the Taco 0015 3-Speed

If you're replacing an existing Taco 0015 3-Speed, the 0015e3 is the ECM-equivalent successor, same flange footprint, same head/flow range, same 3-mode selection logic, with up to 85% lower energy consumption. Most installations swap in without piping changes.
