Grundfos 92603110 ALPHA HWR 15-55 SF/T High-Efficiency Hot Water Recirculation Pump 115V

The Grundfos ALPHA HWR 15-55 SF/T is a high-efficiency variable speed circulator pump engineered for domestic hot water recirculation systems with dedicated return lines. Built with a corrosion-resistant stainless steel housing and an advanced ECM (Electronically Commutated Motor), this pump delivers instant hot water throughout the home while meeting DOE energy conservation standards taking effect in 2028.

Advanced Control Features:

• Seven operating modes including AUTOAdapt temperature control with automatic flow adjustment, manual temperature control, and 24/7 continuous operation
• Integrated digital timer for scheduling on/off hours to reduce energy consumption when hot water isn't needed
• Built-in temperature sensor eliminates the need for external aquastat installation
• Optional Grundfos GO and HOME app connectivity via Bluetooth for remote scheduling, diagnostics, and performance monitoring
• FLOWSENSE technology reduces flow-accelerated corrosion by controlling water velocity in recirculation pipes

Key Specifications:

• Flow Rate: 8.37 GPM (rated)
• Head Pressure: 11.16 feet (rated)
• Maximum Operating Pressure: 174.92 PSI
• Temperature Range: 32°F to 131°F ambient
• Connections: GF15/26 two-bolt flange on both ends

Installation Benefits:

• Dry-run protection prevents damage to bearings and shaft seals during setup and operation
• Self-venting capability in any setting ensures quiet operation
• Compact design fits with both tank and tankless water heaters
• AUTOAdapt setting simplifies commissioning without manual setpoint adjustment

The ALPHA HWR 15-55 SF/T replaces the Grundfos UPS15-55 model, offering significantly improved energy efficiency and smart control features for modern residential hot water systems.
