The Immersion Copper Rod Heater with Thermostat is a well-known type of electric heating solution for both residential, commercial, and industrial use and is an example of immersion heaters that change electrical energy to direct heat when the heating element is in contact with that which is to be heated.
Working Principle
A Heater consists of a resistive heating element (the copper rod), that under electrical load causes a joule heating effect, as the electric current passes through the element, it generates heat that is directly transferred to the liquid surrounding that copper rod/element (generally water), and when the water reaches the set temperature, the thermostat shuts off the power supply keeping the watertemperature constant and improving energy conservation and safety.
Why Copper?
The use of copper is due to thermal conductivity, corrosion protection in clean water situations, and long working life. Copper has faster than steel in heat transfer and is best suited for the typical domestic water heating application.

Role of the Thermostat
A built-in thermostat is critical for automatic temperature control, preventing overheating and dry burning. Advanced models may feature a manual reset function (thermal cut-off switch) to enhance operational safety.
