About Ruud Water Heaters
Ruud water heaters represent the premium tier within Rheem Manufacturing's portfolio, carrying a distinguished heritage that dates back to 1897 when Edwin Ruud invented the automatic storage water heater. This Norwegian immigrant's innovation revolutionized home comfort by providing reliable hot water on demand, and the Ruud name has remained synonymous with quality and innovation for over 125 years. Today, Ruud operates as Rheem's upscale brand, offering enhanced features, extended warranties, and advanced technologies that appeal to discerning homeowners and professional contractors seeking top-tier performance. The brand maintains separate branding and product positioning while benefiting from Rheem's manufacturing scale and distribution network.
