Abstract: A method to heat water in an electrical boiler includes storing user's requests of hot water in association with corresponding times of requests, heating water in advance to a next user's request, wherein the next user's request is estimated on the stored user's requests, detecting a start time of a power request from the electrical boiler, detecting a stop time of the power request, determining that a user's request of hot water has occurred if a time difference between the detected stop time and the detected start time is longer than a predetermined time, the predetermined time being a time of activation of the electrical boiler, storing the determined user's request in association with a time of the user's request, estimating a next user's request based on the stored user's request and activating the electrical boiler to heat water in advance with respect to the estimated next user's request.

Abstract: A method for recharging an accumulator of an electric vehicle is disclosed, the method including recording information on past usages of the accumulator locally at a point of connection of the accumulator to a grid; locally estimating information on a future usage of the accumulator, taking in input the information on past usages; and locally programming an energy flow between the grid and the accumulator based on the estimated information.

Abstract: A method and a device to heat water in an electrical boiler are disclosed. The method include the steps of storing user's requests of hot water in association with corresponding times of requests, heating water in advance to a next user's request, wherein the next user's request is estimated on the stored user's requests. The device is the hardware implementing the method.
