Cost reduction with localized electric water heating systems. Maintenance burden is also reduced compared to central water heating for showers in hotel rooms.

Hot water supply systems in accommodation facilities have primarily relied on central systems using combustion-type boilers powered by gas or heavy oil. Central hot water supply, which covers all hot water needs of the facility, requires large storage tanks and ample installation space. The piping from the storage tank to the hot water outlets requires extensive lengths and numerous connections, resulting in significant initial costs as well as ongoing maintenance expenses over time. The EIWX-G300A1 is a localized hot water supply system designed for accommodation facilities. It allows for the reduction of maintenance labor and costs associated with the central hot water supply method. Additionally, it offers various hot water settings, including temperature adjustments and switching between temperature and flow priority functions, and is easy to install, thereby alleviating the burden on accommodation facilities. <Product Features> - Compact wall-mounted water heater that can be installed in guest rooms - No need for drainage treatment, making installation simple - Multi-functional setting panel allows for temperature settings in 1°C increments (30 to 60°C) - Switchable settings for temperature priority and flow priority functions - Equipped with a function to shut off water supply in case of abnormalities such as leaks, ensuring enhanced safety features.

basic information

Not only from a cost perspective, but in the future society aiming for decarbonization, there is also a movement to shift the way hot water is supplied, such as transitioning from combustion-type boilers to electric heat sources. As a result, there is an increasing number of cases adopting local hot water supply systems in guest room facilities, which are easier to maintain and more cost-effective, and Itomic will cooperate as a professional in hot water supply. Until now, hot water supply systems in accommodation facilities have primarily used central systems with combustion-type boilers utilizing gas or heavy oil. Central hot water supply, which covers all hot water needs of the facility, requires large storage tanks and ample installation space. The piping requires a vast length and number from the storage tank to the hot water supply points, leading to significant burdens not only in initial costs but also in maintenance costs over time.
