The Grundfos MAGNA1 32-60 GF N (product number 98126821) is a variable-speed ECM circulator for hydronic heating, cooling and domestic hot-water systems, delivering up to 19.69 ft of head. Its permanent-magnet motor and integrated controller give an energy efficiency index of EEI 0.20 — well inside the 0.23 ErP benchmark, and a fraction of the draw of a fixed-speed circulator. Power input modulates from 8.71 W to 107 W with demand.
