State of the art performance for hydronic, radiant heat and snowmelt applications. The Taco Bumble Bee® is a wet rotor, variable speed "smart" circulator. The Bumble Bee delivers the ultimate 1-2 punch of electrical savings and system efficiency (fuel usage) cost savings. The unique ECM motor design saves over 50% of the electrical energy compared to conventional fixed speed and 3-speed circulators. When operated in the Delta-T mode it greatly increases the overall efficiency of the boiler so less fuel is used, which equals money saved. The Bumble Bee also increases whole house comfort by continuously adjusting its speed to delivering the right amount of BTU's (heat) at the right time to the right place in the system.
