How does a geyser work?

Talking about the basic working of a geyser, it works on an electrical resistance heating element that is located in the middle of the tank. The current passes via the heating element and the thermostat, which is used to control the temperature of the water whenever the water heater is turned on. If the water heater has a storage tank, then the heating element heats the water whenever it is required.

The instant water heater takes water from the primary tank, while a storage water heater has a separate tank onboard as a component that keeps a custom amount of water for usage. The geysers that ship with thermostat help in monitoring the temperature of the water that is being heated up to a set temperature. We will further move on to the types of water heaters or geysers.
