Nippon Thermoener Co., Ltd. was established in 1961 as a member of the Takuma Group, specializing in the manufacturing and sales of various boilers and heaters. Since our founding, under the corporate philosophy of “Kikan Hōkoku (Contributing to society through boiler technology),” we have contributed to society by providing a wide range of products in the fields of thermal energy essential to people’s daily lives and industrial activities.
The technological expertise we have developed over 60 years, together with our products, services, and the strong trust we have built with our customers, are invaluable assets of our company.
In April 2026, Nippon Thermoener entered a new chapter through a merger with IHI Packaged Boiler Co., Ltd. By bringing together the technologies, experience, and human capital cultivated by both companies, we have taken a new step toward continuing to deliver products of greater value to society, even in times of rapid change.
Today, the world is moving toward a decarbonized (carbon-neutral) society. As the environment surrounding energy continues to change significantly, we are required more than ever to demonstrate strong technical capabilities, flexible ideas, and the ability to put them into action.
As a specialized manufacturer of heat source equipment, the renewed Nippon Thermoener aims to face these social challenges directly and to remain an essential company that contributes to their solutions.
We are working to improve the energy efficiency of our existing products, including boilers and hot water heaters of various sizes, and to reduce resource use and environmental impact through solutions such as CO2 concentration-type once-through boilers. At the same time, we are actively expanding our product lineup, including hybrid systems that combine existing heat source equipment with heat pumps, as well as products compatible with carbon-neutral fuels such as biomass, hydrogen, and waste cooking oil.
We will continue to stay close to our customers, listen carefully to voices from the field, and consistently consider what products and services are truly optimal, and deliver them. We also aim to be a company where each individual approaches their work with sincerity and continues to embrace “change and challenge.” With this commitment firmly in mind, we will move forward together.
We sincerely invite you to look forward to the future of Nippon Thermoener as we take this new step ahead.
