Usage

The Grundfos UPSe 15-58 F is designed to circulate water in closed-loop hydronic heating systems. It is commonly installed in residential boilers, radiant floor heating, baseboard heating, fan coil units, geothermal systems, and light commercial HVAC applications. The ECM motor automatically adjusts pump performance using constant-pressure, proportional-pressure, or fixed-speed modes to improve comfort while reducing electrical consumption. Features such as self-venting, dry-run protection, and a removable power connector simplify installation and maintenance. Because the pump has a cast iron housing, it is not intended for potable domestic hot water systems.
