That prophetic little quote from “The Man Who Shot Liberty Valance” pretty much sums up where our industry is today with residential ECM circulators. So many myths, many of them downright crazy, make it nearly impossible to make clear-headed and smart decisions for your customers.

The new ECM Pump-Less-Volute uses a permanent magnet motor that is up to 40% more efficient than a standard induction motor.

One of the “delights” of designing hydronic systems is looking for synergistic opportunities, where one device provides multiple functions or benefits that would otherwise require two or more separate devices.

The DOE ruling is delayed indefinitely, but new energy efficiency labeling is already in the works.

Some things don’t vary proportionally.

When designing hydronic circuits, most of us focus on what’s necessary for that circuit to absorb thermal energy at a heat source, carry it along like a conveyor belt and release that energy at one or more heat emitters.

The building will serve as both a Regional Sales Excellence Center and the company's Asian Operations headquarters.

Circulators react to occupant behavior and tailor energy use to meet system demands.

Central Sales will sell the AquaMotion product line through the wholesale distribution channels. 

There are hydronic design concepts in which flow must pass backward through a non-operating circulator, perhaps thousands of times over the life of the system.
