Williams Comfort Products 5ES10H2GR Electric Solar Pump

Product Description

The WILLIAMS COMFORT PRODUCTS 5ES10H2GR is a 1 HP electric solar pump designed for solar thermal and hydronic circulation systems. This unit is configured for 4-wire, 3-phase electrical operation and includes a 2-gallon capacity, making it suited for medium-duty circulation duties in solar-assisted heating applications. At 98 pounds, the 5ES10H2GR is a substantial assembly built for demanding installations where reliable fluid movement is required. Licensed HVAC technicians and solar thermal installers are the primary trade professionals who work with this type of equipment.

This pump is used in solar thermal collection systems, radiant floor heating loops, and related hydronic applications where a 3-phase power source is available. The 4-wire, 3-phase configuration is typical of light commercial or larger residential solar installations. The 2-gallon vessel capacity provides buffer volume for system fluid management. It is well suited for installations requiring a motor-driven circulator with higher-torque 3-phase operation rather than standard single-phase residential pump configurations.

Key Features

• 1 HP motor output for dependable fluid circulation in solar thermal and hydronic systems
• 4-wire, 3-phase electrical configuration supports commercial-grade power supplies
• 2-gallon capacity suitable for medium-duty solar loop applications
• Sold individually as a complete pump assembly

Compatibility

Designed as an OEM-style replacement or direct installation pump for solar thermal and hydronic circulation systems requiring a 1 HP, 3-phase electric pump assembly.

Installation Notes

Installation should be performed by a licensed HVAC technician or solar thermal installer familiar with 3-phase electrical systems and hydronic piping. Shut off all electrical power to the circuit before making any wiring connections, and isolate the fluid loop before removing or installing the pump. Local electrical codes including NEC requirements for 3-phase motor wiring apply. Verify system fluid compatibility and pressure ratings before commissioning the pump.
