About Itomic

ITOMIC is a pioneer company of commercial electric water heater manufacturers from Japan, which was founded in 1948.

As a specialized manufacturer, ITOMIC has more than 70 years of experience in electric water heaters. Since our founding, we have continued to provide products and services based on safety and security. We have also worked hard to develop our own technology and improve product performance.

ITOMIC developed the world’s first commercial CO2 refrigerant heat pump water heater in 2002 with the technology cultivated through 70 years of experience.

Now, we have delivered not only in Japan but also in South Korea, Taiwan and Australia, and we are steadily increasing the delivery record to the world.

Furthermore, in China, we have been working with partner companies since 2019, and have succeeded in local production of CO2 heat pump water heaters in China, and the introduction record in China is steadily increasing.

ITOMIC has already delivered CO2 heat pump water heaters for more than 20 years and has experience in responding to the needs of many customers.

ITOMIC will actively promote the spread of commercial CO2 refrigerant heat pump water heaters not only in Japan but also around the world to prevent global warming.

We will strive to popularize “clean & green electric hot water supply” that does not pollute the earth. We believe that it is the role of ITOMIC to play a role in preventing global warming, to protect a sustainable society, and to protect the blue sky.
