Taco introduces its next generation Bumble Bee high-efficiency variable speed circulator – model HEC-2. The Bumble Bee is a wet-rotor circulator using the very latest in ECM, permanent magnet motor technology. It uses up to 85% less electricity than a standard circulator, and its out-of-the box settings and 360˚ swivel flange makes it easy to install.
The right circulator needs to do more than just move water. Taco’s exclusive Delta-T technology boosts electrical savings by 15-19 times by making the entire system run more efficiently. 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.
The Bumble Bee operates over a broad performance range, with flow up to 15 gpm and head up to 15 feet. Factory pre-set to run in Delta-T mode, it can also be programmed for variable speed setpoint operation to maintain a fixed supply temperature or dialed-in to one of four fixed speeds. With all the options, the Bumble Bee is an ideal choice for many hydronic, radiant heat, boiler protection, fan coil and snowmelt applications – residential or light commercial.
An integral flow check (IFC) and two plug-in remote temperature sensors are included in the carton. The circulator can accept 115-230v input power and can be easily wired to any Taco Switching Relay or Zone Valve Control for on/off operation. The LED displays mode, real-time watt usage and gpm flow.
Taco’s e-smart tag – which the Bumble Bee proudly wears – identifies Taco’s most resource-saving technology. The Bumble Bee is engineered and manufactured in our Cranston, RI plant for energy savings, ease of installation, versatility in the field and ultimate comfort… so you can do your best work.
