We can heat water using a water Dispenser, Stove, Electric Kettle, and Geyser, a.k.a. water heater. Indeed, we use water dispensers and an electric Kettle for drinking. But for Bathing and Cleaning, we prefer to use Geysers because of the amount of water used.
Water heaters are of three types, Instant Geyser, vertical Geyser, and Horizontal Geyser. We have explained the best instant geyser in India based on the heating element, Capacity, Materials used to build, Hard water resistance, electricity consumption, and many more.
