After more than ten years of development, the technology of electric water heaters has continuously improved. The industry has successively introduced innovative products such as anti electric walls, anti electric brakes, 3D rapid heating, frequency conversion and capacity increase. Electric water heaters have continuously improved in safety, energy conservation, heating speed, water output, and other aspects, and market sales have continued to grow over the years.

Although the volume of an ordinary fast heating electric water heater is similar to that of a dual mode electric water heater, the internal structure is vastly different. Compared to a water storage electric water heater, a fast heating electric water heater is only smaller in size and has higher power, so it is indeed faster in heating speed than a water storage electric water heater. However, it cannot achieve instant heating in spring and autumn and needs to be preheated, which requires waiting. However, a dual mode electric water heater can only achieve instant heating in spring and summer The instant heating mode is available for the three seasons of autumn, which is instant heating.
