Function: Also known as an immersion rod or bucket heater, it is a portable electrical device used to heat water directly within a container. It works by using an electric resistance heater (the metal coil) that heats the surrounding water.
Usage: It is fully submersible and can be used in various containers like buckets or tubs to heat water for different applications, such as for hot beverages, cooking, or general use where hot water is required.
Safety Precaution: The device must always be fully submerged in water during the heating process to prevent damage or safety hazards.
Energy Efficiency: Immersion heaters run solely on electricity and can be an effective way to heat water, although they might consume a significant amount of electricity compared to other methods like gas boilers.
