Abstract
An electrical water heater that receives a load shedding request signal uses a temperature sensor that is positioned so as to measure a water temperature in a lower area of a tank of the water heater. A controller continuously determines a salubrity index of the water heater as a function of the temperature measured by the sensor and a time measurement The controller decides to interrupt an electrical power supply of the water heater through a switch so as to interrupt or not interrupt an operation of the water heater upon receipt of the load shedding request signal and only if the salubrity index meets a preestablished criterion.
