What is an electric storage water heater, and how does it work

An electric storage water heater is a geyser that heats water using an electric element and stores it in an insulated tank for ready use. Cold water enters the tank, gets heated to a set temperature controlled by a thermostat, and stays hot for a longer time due to insulation. When you turn on the tap, hot water flows out instantly while the tank refills and reheats, ensuring a consistent and convenient hot water supply.
