What Is an Immersion Rod?
An immersion rod is an electrical water heater designed to heat water when the heating element is immersed in a suitable water container.
It is commonly used with buckets and other compatible containers.
The appliance generally consists of:
- Heating element
- Protective body or metal tube
- Handle
- Electrical cable
- Plug
- Indicator light on some models
When connected to electricity, the heating element becomes hot and transfers heat to the surrounding water.
Because immersion rods do not usually require permanent plumbing, they are often considered a simple alternative to installing a geyser.
How Does an Immersion Rod Work?
The operating principle is relatively simple.
When the immersion rod is placed into water and connected to electricity, electrical energy is converted into heat by the heating element.
