The WILLIAMS COMFORT PRODUCTS 5ES05H2G is a 0.5 horsepower electric solar pump designed for solar thermal and hydronic circulation systems. It features a 3-way, 3-port valve configuration, allowing for directional flow control within a closed-loop or open-loop solar heating circuit. With a 2-gallon capacity rating, this pump is sized for residential and light commercial solar thermal installations. Licensed HVAC technicians and plumbing professionals are the primary installers. The pump moves heated fluid from solar collectors to storage or distribution points, making it a core component in solar domestic hot water and space heating systems.
This pump is suited for residential solar thermal systems, including solar domestic hot water setups and solar-assisted space heating configurations. The 3-way, 3-port design supports diverting or mixing valve functions within a loop, giving installers flexibility in system layout. It is typically installed at the solar collector return or supply line where flow direction or blending must be managed. The 0.5 HP motor provides adequate head pressure for single-zone residential solar loop applications.
Designed as an OEM-style replacement or direct-fit pump for residential and light commercial solar thermal and hydronic circulation systems requiring a 3-way, 3-port, 0.5 HP electric pump.
Installation should be performed by a licensed plumber or HVAC technician familiar with solar thermal and hydronic systems. Shut off all fluid supply lines and de-energize the system before removing or installing the pump. Follow applicable local plumbing codes and manufacturer wiring requirements when making electrical connections. Verify flow direction markings on the pump body before securing final connections.
