Wall-mounted 3L small electric water heater has undergone a model change.

  • PRODUCT

We are pleased to announce that we will fully model change the wall-mounted 3L electric water heater "ESW03/M3 series," which has been widely appreciated for handwashing purposes, and it will be newly released in December 2025. The new model will feature a front cover that takes design aspects into consideration, resulting in a sleek appearance, and we have also reviewed the water supply pressure and installation methods, significantly improving convenience compared to the previous products. We kindly ask you to consider this opportunity. 【Main changes from the old product】 1) A front cover is included. The piping connection part is concealed even when installed in an exposed manner, taking design aspects into account. 2) Improved piping connection ports and changes in the method of fixing to the wall have enhanced the ease of installation. 3) The primary side water supply pressure has been changed from 0.5MPa to 0.75MPa.

Participation in the "Japan Climate Initiative" Climate Change Initiative

  • COMPANY

Japan Itomic Co., Ltd. (Headquarters: Sumida-ku, Tokyo, President: Hirofumi Moriya) announced on April 27, 2021, its participation in the "Climate Change Initiative," agreeing to "join the forefront of the world in the pursuit of decarbonization." The "Climate Change Initiative" is a loose network of various entities, including companies, local governments, organizations, and NGOs, that actively engage in climate change measures, excluding national governments. In the United States, businesses, state governments, and municipalities have formed a network called "We Are Still In," which continues to work on strengthening climate change measures even after the Trump administration's announcement to withdraw from the Paris Agreement. Following this initiative in the U.S., movements to create cross-sectoral organizations of diverse actors outside of national governments have begun in other countries as well. The "Climate Change Initiative" aims to collaborate with these international movements.
