The Grundfos ALPHA 15-58 is a high-efficiency circulator pump designed for heating systems. It is built with an ECM (Electronically Commutated Motor) for maximum performance. This digitally connected pump features intelligent controls with constant pressure, proportional pressure, and constant curve settings, each offering adjustable levels and AUTOADAPT functionality. With fewer callbacks than other pumps, the Grundfos ALPHA 15-58 ensures reliable, efficient operation. Ideal for residential and light commercial applications for maintaining a steady, energy-efficient heating system. The ALPHA meets the energy conservation standards for circulator pumps the Department of Energy established, which will take effect in May 2028.
