AquaMotion designed the variable speed Model AM55, AquaMotionSmart Einstein, cast iron ECM cartridge circulators as the most energy efficient circulator for closed loop hydronic heating systems, radiant heating, and indirect water heating applications. The variable speed settings allow the circulator to automatically adapt to system demand to improve entire heating system efficiency. The high head and flow performance allows the Einstein to meet the demand of virtually all residential heating applications.

With an Amp draw of only 0.07 to 0.58 amps, and watt consumption of just 5-38 watts the Einstein is the most energy efficient ECM on the market. AquaMotion’s universal 4-bolt flange design reduces inventory and cost while simplifying installation. Circulator comes with BICV™ built in check valve.

Einstein circulator replaces the Grundfos Alpha and Taco OOE models and other ECM circulator models.
