Grundfos’ ultra-efficient ALPHA circulators are paired as options on most U.S. Boiler gas cast-iron heating products. Made in the United States, the pump is designed for circulating liquids in light commercial and residential heating systems. It features AUTOADAPT technology, which automatically analyzes the needs of the system and then adjusts operation to changes in demand. By learning the patterns of consumption, it can save end users up to 85% in energy costs when compared to a conventional circulator.
