Taco 0015E3-F4 – ECM High-Efficiency Circulator – Cast Iron, 16 GPM, Universal Flanged

The Taco 0015E3-F4 is a high-efficiency, variable-speed circulator pump designed for closed-loop hydronic heating systems such as radiant or baseboard heating. It features an electronically commutated motor (ECM) with three selectable constant-pressure modes, offering flexibility, energy savings, and reliable performance. This model is not for potable water or chilled water applications.
