Williams Comfort Products 5ES05H1G Electric Solar Pump

Product Description

The WILLIAMS COMFORT PRODUCTS 5ES05H1G is a 0.5 HP electric solar pump designed to circulate fluid through solar thermal systems. Rated at 0.5 horsepower, this unit is built for single-gallon flow configurations and uses a 3-way, 3-port valve arrangement to direct fluid movement within the system loop. It is installed by licensed HVAC technicians and solar thermal specialists working on residential or light commercial solar heating applications. The pump supports efficient fluid transfer between the solar collector array and the storage or distribution side of the system.

This pump is suited for solar thermal hydronic systems where a reliable, electrically driven circulation pump is required. The 3-way, 3-port configuration makes it appropriate for installations that require diversion or mixing valve functionality integrated into the pump assembly. It is typically installed in mechanical rooms or utility spaces as part of a closed-loop or open-loop solar thermal setup. Technicians working on solar domestic hot water systems or solar space heating systems will find this pump applicable to standard solar loop plumbing configurations.
