Immersed electrode boilers produce steam, hot water or superheated water. The electrodes and counter-electrodes are fully immersed below the water level. Depending on the power requirement, an insulating tube rises or falls to cover or uncover the electrode, thereby regulating the flow of electrical current and the Joule effect.
Water jet boilers only produce steam. The electrodes are sprayed with water from the central column, and a mask moves up or down depending on the power requirement to cover or uncover the jets, which directly affects the flow of current to the counter electrode and the induced Joule effect.
