Itomic electric instant water heater

Electric instant water heaters boil only the amount of water you need. It is an energy-saving and cost-effective hot water supply system that does not consume power for keeping water warm!

Electric instant water heaters are devices that use an electric heater built into the main unit to instantly heat water only when it 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 water 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 Japan, there is an expectation for a transition from combustion-based equipment in both industrial and civilian sectors, as well as advancements in high-efficiency technologies, leading to a wider adoption of electric energy. As a domestic manufacturer specializing in electric water heaters, we believe that our lineup of instant electric water heaters can further contribute to societal needs 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 instant 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 there is no shortage of hot water for a sustainable society.
