Below are results of a third party case study that was done as a pilot project with Efficiency Vermont to verify the energy savings comparing side by side existing Taco 1600 series to the first generation Grundfos Magna’s. As you can see, the energy reductions were impressive. The savings below do not include the elimination of maintenance costs that are not needed on the Grundfos.
Since the study was completed, each mechanical room on their campus has been upgraded to Grundfos E-Solution pumps which are Alphas, Magna 3, TPE’s and CRE-DP multi-stage pump series. All pumps except the Alpha’s are connected to their building management system with the Grundfos supplied BACnet CIM cards.
