Hayward's TriStar VS 2.7 HP Variable-Speed Pool Pump belongs to the TriStar family—the most energy-efficient pumps among leading brands, according to EPA ENERGY STAR third-party testing. It offers energy savings of up to 90%, or $1500 per year, with a super-efficient, ultra-quiet permanent magnet totally enclosed fan-cooled motor and integrated electronic drive. This upgraded motor drive delivers significantly quieter high-speed operation than other leading models, while a dual-voltage capability provides easy installation in both new and existing pool pads—no costly rewiring required. In addition, its all-in-one controller compatibility makes it easy to integrate with any new or existing automation system. From installation to operation, it's one of the industry's easiest, most efficient pump upgrades.
