How does a Electric Geyser Work?

Chances are high that you have an electric geyser at home, to heat up water. Ever wondered how it works? Here is how.

In a way, it is not much different from a common immersion rod that you can dip into your bucket, plug into the power socket and have the water heated up. The only difference is the level of sophistication and slight automation in the geyser.

The geyser consists of a water tank fitted with two pipes – one for inlet of cold water and the other for outlet of hot water. The water tank is fitted with heating elements which are controlled by thermostats. The thermostats ensure that water is not heated above a set temperature value. The tank is normally covered with some insulating material and enclosed inside a metal casing.

The principle on which the geyser works is simply the conversion of electrical energy into heat through the use of heating elements to raise the temperature of water through conduction of the heat to the water.

Both the heating elements do not function simultaneously. First the top heating element functions until the upper tank is hot and then the function is transferred to the bottom heating element, which has its own thermostat. The thermostat is mainly a bi-metallic disc with each metal having a different co-efficient of expansion for heat. So, when it gets heated up, it bends and the contact with the switch is broken.
