Wilo ECM & Energy Savings

Energy is a valuable commodity. That’s why Wilo created the world’s first high-efficiency circulator in 2001. With the help of Electronically Commutated Motor (ECM) technology, Wilo’s efficient, functional and flexible pumps for heating, cooling, and air conditioning reduce annual power consumption by up to 80%. ECM essentially comprises a synchronous motor with a permanent magnet rotor. The unique rotor-stator construction helps eliminate electrical losses.

Wilo red buttonThe Stratos GIGA, multiple models of Wilo Stratos and Stratos Z circulators are energy-efficient and feature “red button” technology, LED displays, and control modules that enable integration with building management systems.

Stratos, Stratos D and Stratos Z high efficiency ECM circulators standard warranty is 4 Years.
