Taco 0018e-2F4 ECM High Efficiency Circulating Pump with Bluetooth

Optimize Taco 0018e-2F4 ECM Bluetooth Circulator — 18 ft Head, 16 GPM (Universal 2-Way Flange)

Dial in quiet, efficient hydronic flow with app control. The Taco 0018e-2F4 is an ECM, variable-speed wet-rotor circulator built for zoning with circulators or zone valves, panel radiators with TRVs, and domestic hot-water recirc on closed loops. Bluetooth lets you set modes, run diagnostics, and generate validation reports from your phone. With max 18 ft head and up to 16 GPM, it covers a wide range of residential circuits while using as little as 4–44 W—saving up to 85% electricity vs. PSC pumps. The F4 model’s universal 2-way flange simplifies retrofits and orientation on the job.

Save Energy With ECM Control

The permanent-magnet ECM motor trims power draw to just 4–44 watts, reducing circulator electricity use by up to 85% versus comparable PSC pumps. Choose constant or proportional pressure to match zone valves or TRVs, or lock a fixed speed for a zone circulator—right from the dial or the app.

Bluetooth App = Faster Setup & Proof

Use the Taco 0018e Mobile App to select modes, view real-time performance, and create operation/validation reports with diagnostics and history. It’s a quick way to document final settings and confirm system behavior on handoff.

Quiet, Reliable Operation

Multi-color LED status, SureStart auto-unblocking/air-purge, and the BIO Barrier help keep the cartridge clean and start-ups smooth. The wet-rotor design keeps sound levels low in living areas.

Installer-Friendly Universal Flange

The F4 “universal 2-way” flange pattern eases orientation in tight spaces and aligns with common hydronic flanges (3/4?–1-1/2?). Dual knockouts and 6? stranded leads simplify wiring; the pump is double-insulated—no ground required.

Sized Right For Most Loops

With 18 ft of head and 16 GPM max, the 0018e-2F4 covers many baseboard, panel radiator, and manifold circuits. Use the pump curve to fine-tune speed or select constant/ proportional pressure settings that keep comfort steady as zones open and close.

Built For Closed Systems

Cast-iron construction is intended for closed-loop hydronic applications and compatible with water or up to 50% glycol. For potable/open systems, choose the 0018e stainless-steel variant instead.
