Rinnai home appliances

Rinnai Corporation, founded in 1920 in Nagoya, Japan, is a global leader in the manufacturing of gas appliances and water heating systems. The company established its reputation through innovations in pressurized oil burners and has since expanded into high-efficiency tankless water heaters, kitchen stoves, and commercial heating equipment.

While the company is headquartered in Japan, it operates extensive manufacturing facilities across the globe to serve local markets. Major production hubs include Japan, the United States, Australia, Brazil, and several countries across Southeast Asia. This distributed manufacturing model ensures that products are engineered to meet specific regional safety standards and energy requirements.

The brand remains under the ultimate ownership of Rinnai Corporation, an independent public company listed on the Tokyo Stock Exchange. As a specialized engineering firm, Rinnai maintains vertical control over its brand identity and product development, operating various local subsidiaries such as Rinnai America and Rinnai Australia to manage regional distribution and customer support.
