The Tahoe Truckee Unified School District Administrative Building experienced a 76% energy usage reduction after replacing two 7.5HP competitor pumps with a Wilo Stratos-D 3×3-40.  The ECM circulator design considerably reduces space requirements, as well as material and labor costs for owners, contractors, plumbers and electricians.

The circulator will stage/rotate every 24 hours and optimize the impeller speed according to system demand.  There is no need for external controls; the pump, motor, and computer are all self-contained and ready to run right out of the box.  With Wilo Red Button technology, setting and controlling the pump is a breeze.

E-minus, a trusted Wilo partner, verified the energy-saving results.  After proving the new pump yielded a 76% reduction in energy usage, the district showed a $2,609 annual energy savings. With results like these, they now plan to retrofit all 13 facilities in the district.
