This pump moves fluid through a closed-loop or open-loop solar collector circuit, maintaining steady flow rates required for efficient heat transfer. It features a 3-gallon flow capacity with a 3-way, 3-port valve configuration, allowing for directional flow control without additional bypass hardware. Licensed HVAC and plumbing contractors typically specify this unit in solar-assisted domestic hot water and space heating installations where reliable pump performance is critical to system efficiency.\u003c\/p\u003e\n\u003cp\u003eThe 5ES15H3G suits residential and light commercial solar thermal installations. The 3-way, 3-port design integrates into systems that require zone switching or bypass capability at the pump assembly, reducing the number of separate components needed in a solar loop. It is appropriate for glycol-based or water-based heat-transfer fluid circuits typical in drainback and pressurized solar collector systems. Plumbing and HVAC contractors working on solar thermal retrofits or new construction installs will find this pump sized for common residential collector arrays.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.5 HP motor output suited for solar thermal and hydronic loop applications\u003c\/li\u003e\n  \u003cli\u003e3-gallon rated flow capacity for consistent fluid movement through collector circuits\u003c\/li\u003e\n  \u003cli\u003e3-way, 3-port valve configuration enables directional control at the pump assembly\u003c\/li\u003e\n  \u003cli\u003eElectric-driven operation compatible with standard solar system controls and controllers\u003c\/li\u003e\n  \u003cli\u003eSold as an individual unit with a minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install pump for solar thermal and hydronic heating systems requiring a 1.5 HP, 3-way, 3-port pump assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumbing or HVAC technician familiar with solar thermal systems and applicable local codes. Shut off power to all connected controls and isolate the fluid circuit before removing or installing the pump. Verify that the heat-transfer fluid type and system operating pressure are compatible with the pump before commissioning. Follow IFGC and IPC guidelines as applicable, and ensure all electrical connections comply with NEC requirements for the installation environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Output\u003c\/strong\u003e: 1.5 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Configuration\u003c\/strong\u003e: 3-gallon, 3-way, 3-port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 98 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662459946492\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMS COMFORT PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5ES15H3G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51347903119666,"sku":"5ES15H3G","price":8531.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310542130.jpg?v=1782115918","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-5es15h3g-electric-solar-pump","provider":"Voomi Supply","version":"1.0","type":"link"}
