Taco’s HEC-2 Bumble Bee high-efficiency variable-speed circulator is a wet-rotor circulator that uses the latest in electronically commutated motor technology. It consumes up to 85% less electricity than a standard circulator, while its out-of-the-box settings and 360° swivel flange make it easy to install. With the ability to determine the exact flow required to match ever-changing building heat loads, the Bumble Bee can reduce boiler short-cycling, increase total system efficiency, maximize energy savings and improve consumer comfort.
