Williams Comfort Products 5ES15H5G Electric Solar Pump

Product Description

The WILLIAMS COMFORT PRODUCTS 5ES15H5G is a 1.5 HP electric solar pump designed for solar thermal and hydronic heating systems. This 3-way, 3-port pump circulates fluid through solar collector arrays and storage or distribution loops, maintaining flow under the operating conditions common to residential and light commercial solar installations. Rated at 1.5 HP, it is built to handle the head pressure and flow demands of larger solar thermal setups. Weighing 106 pounds, it is a robust, heavy-duty unit intended for professional installation by licensed HVAC or plumbing technicians.

The 5ES15H5G is suited for solar thermal heating systems where a single pump must manage fluid routing across multiple circuit paths. The 3-way, 3-port configuration allows flow diversion or mixing between collector, storage, and distribution legs without requiring separate inline valves for basic switching functions. A 5-gallon system capacity designation indicates compatibility with mid-to-larger solar loop volumes typical of residential whole-home or small commercial solar water heating and space heating applications.

Key Features

• 1.5 HP motor output for higher flow and head pressure demands in solar thermal loops
• 3-way, 3-port design enables fluid diversion or mixing without additional switching valves
• 5-gallon rated system capacity suits mid-to-larger solar collector arrays
• Heavy-duty construction at 106 pounds for durable, long-term installation
• Sold individually, allowing single-unit replacement or new system installation

Compatibility

Designed as an OEM-style replacement or new-install pump for solar thermal and hydronic circulation systems requiring a 3-way, 3-port electric pump at 1.5 HP. No specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a licensed plumbing or HVAC technician familiar with solar thermal and hydronic system piping. Shut off and depressurize the system and allow fluid to cool before removing any existing pump or fittings. Follow applicable IPC and local plumbing codes for pipe sizing, pressure ratings, and fluid compatibility. At 106 pounds, use appropriate lifting equipment and ensure the mounting surface and supports are rated for the unit weight before securing.
