Rinnai was founded in 1920 by Hidejiro Naito and Kanekichi Hayashi, who quickly established a tradition of constant improvement. They started by manufacturing and selling pressurized oil cooking stoves. By the early 1930s, they expanded into gas appliances, including cooking stoves, ranges and space heaters; and since 1964 Rinnai has been efficiently heating water. Today, more than 30 million Rinnai Tankless Water Heaters have been installed worldwide.
Established in 1974, Rinnai's North American operations continue to expand. In 2001, we opened our state-of-the-art distribution, research and training facility in Peachtree City, Georgia, and have since added training facilities in California.
As one of the world’s largest gas appliance manufacturers—with headquarters in Japan and a network of 20 branches and 86 sales offices in 13 countries—we have attained a truly global presence and perspective.
