Williams Comfort Products 5ES15H3GR Electric Solar Pump

Product Description

The WILLIAMS COMFORT PRODUCTS 5ES15H3GR is an electric solar pump rated at 1.5 HP with a 3-gallon capacity and a 4-way, 3-port configuration. This pump is designed to circulate fluid through solar thermal systems, moving heated liquid from solar collectors to storage or distribution points. The 4-way, 3-port valve arrangement allows for versatile flow routing within the system. Licensed plumbers and solar thermal installers are the primary trades that specify and install this unit in residential and light commercial applications.

The 5ES15H3GR is suited for solar thermal heating installations where reliable fluid transfer is required between collectors and storage tanks or heat exchangers. Its 1.5 HP motor output supports the flow demands of mid-sized solar loop systems. The 3-gallon specification and multi-port configuration make it appropriate for closed-loop and open-loop solar domestic hot water and space heating setups. Installers working on solar thermal projects will find the multi-port design useful for integrating bypass and diverting functions without additional inline components.

Installation Notes

Installation should be performed by a licensed plumber or certified solar thermal installer in accordance with applicable local plumbing codes and the IFGC where relevant. Shut off all system power and isolate the fluid loop before removing or installing the pump. Verify that system operating pressure and fluid compatibility are confirmed before commissioning. Follow the manufacturer documentation for proper port orientation and mounting position to avoid air entrainment and ensure correct flow direction.
