Energy-saving equipment that considers the environment: Latest model of electric water heating devices [for showering and washing dishes] - Itomic's EIWX series electric instant water heater.

Electric instantaneous water heaters are devices that boil water instantly using an electric heater built into the main unit, only when hot water is needed. Since they do not use fire, they are "safe," they do not produce combustion gases, which is "environmentally friendly," and they do not consume electricity for keeping warm, resulting in high "energy-saving effects." Additionally, because they do not have a storage tank, they can reduce installation space compared to storage-type electric water heaters. In recent years in Japan, there is an expectation for the transition of combustion-based equipment in both industrial and residential sectors, as well as advancements in high-efficiency technologies, leading to an expansion of electric energy use. As a manufacturer specializing in electric water heaters, we believe that our lineup of instantaneous electric water heaters can further contribute to meeting the market needs required in a decarbonized society. Electric energy does not emit CO2 compared to combustion-based energies like gas and oil, and its global expansion is anticipated. Since 1992, our company has been selling electric instantaneous water heaters that "use electricity only when hot water is needed, and only the amount required." We are committed to promoting "clean and green electric water heating" that does not pollute the Earth, playing a role in preventing global warming, and we encourage you to consider our compact energy-saving devices that ensure a continuous supply of hot water for a sustainable society.

basic information

An evolved electric instantaneous water heater that controls hot water supply with high precision The EIWX series electric instantaneous water heater controls hot water supply with high precision through fine settings and the latest control technology, meeting various demands in hot water usage environments. With temperature settings in 1°C increments, a temperature priority mode, and the ability to check the current status, this product offers higher adaptability to on-site needs than any previous electric instantaneous water heater. ■ Multifunctional panel with various settings The temperature setting panel is positioned in a clear location at the center of the unit. The set temperature can be changed in 1°C increments, and the maximum output can be adjusted in 0.5kW increments. This allows for fine adjustments to accommodate various usage situations and energy-saving measures. ■ Temperature priority function unaffected by supply water temperature The temperature of tap water fluctuates. When the water temperature changes, the hot water temperature may also change; however, the "temperature priority mode" allows for hot water to be supplied at the set temperature by adjusting the flow rate with the built-in flow valve. In "flow priority mode," the hot water temperature may change, but the flow rate remains constant.
