What controls the load on an electrode-type electric boiler?

The load on an electrode-type electric boiler is primarily controlled by the amount of electrode covered by water. In this type of boiler, the electrodes are submerged in water, and the thermodynamic process relies on the conductivity of the water to generate heat.

When the electrodes are fully submerged, they can operate efficiently, transferring electrical energy into thermal energy, which heats the water. If the water level drops and the electrodes become partially or completely exposed, the efficiency of the heating process decreases, which can lead to overheating and potential damage to the boiler. Therefore, maintaining an appropriate water level is crucial for regulating the load on the boiler and ensuring safe and efficient operation.

While the amount of electrical current supplied does impact the overall energy input, it is the interaction between the electrode coverage and water level that directly affects the heat generation and load efficiency.
