How Does an Immersion Heater Work?

A steady flow of electricity goes through the heating element, which, in response, heats the water right inside your
tank. Also, an internal or external thermostat regulates the temperature of your water, keeping it ready for use for
your peace of mind.
So, whenever you turn on a tap, a cold, high-pressure stream of fresh water enters the tank and pushes the
heated water out. Once the temperature is high enough, the water rises to the top of your cylinder, right next to
the heating element.

Procedure
1 open the inspection Cover for electrical Terminals, Connection & Thermostat installation in the geyser after
removing power plug.
2 Conduct visual Examination of the Power cord Termination and also terminate at appliance.
3 Check for Proper tightness and good electrical Contact at termination. Replace the Plug pin if found damaged.

4 Conduct insulation resistance on the Cord between the leads, insulation & Earth.
5 Measure the Insulation Resistance between the element and the earth / body..
