JAPAN, January 21, 2026 /EINPresswire.com/ -- Noritz Corporation (Head Office: Kobe, Hyogo, Japan; President and CEO: Masayuki Takenaka), a leading manufacturer of water heating systems, and Nihon Itomic Co., Ltd. (Head Office: Sumida-ku, Tokyo, Japan; President: Hirofumi Moriya) have entered into a partnership to develop their first commercial CO₂ heat pump water heater for the North American market.
As part of this launch initiative, the two companies will showcase the new technology at AHR Expo, one of the world’s largest HVAC&R exhibitions, taking place from February 2-4, 2026 in Las Vegas, Nevada, USA.
Background and Purpose of Partnership
Environmental awareness and decarbonization initiatives have gained more attention over the years across North America, driving strong demand for electrification and heat pump water heating solutions. In line with its medium-term management plan, Noritz has positioned global business expansion as a core growth strategy, with the North American market representing a key focus area.
Noritz and Nihon Itomic first partnered in July 2025 to launch a commercial hybrid water heating system for the Japanese market. Building on that success, the two companies are now leveraging Nihon Itomic’s expertise in electric and CO₂ heat pump technology and Noritz’s proven manufacturing capabilities to jointly develop their first commercial CO₂ heat pump water heater for North America.
Details of Partnership and Future Outlook
Under this partnership, Nihon Itomic will lead product development. Manufacturing will be carried out by RB Corporation (Head Office: Tsuchiura, Ibaraki, Japan; President: Takeshi Tsuji), a Noritz Group company, while NORITZ AMERICA CORPORATION (Head Office: Fountain Valley, California, USA; President and CEO: Jay Hassel) will oversee sales and distribution in the North American market. CO₂ refrigerant-based heat pump water heaters offer a significant reduction in greenhouse gas emissions compared to conventional fossil fuel systems and integrate seamlessly with renewable energy sources. Through this joint development and future market introduction, Noritz and Nihon Itomic aim to accelerate the transition to a decarbonized society and create a future where comfort and environmental responsibility coexist.
