An oven for baking foods, in particular bakery and confectionery products, comprising: a plurality of baking chambers for baking foods each comprising a baking surface on which foods to be baked are positioned; each of said chambers comprising lower heating means, of an electrical type, arranged below the baking surface, and/or upper heating means, of an electrical type, arranged above the baking surface and distanced therefrom by a predefined distance so that the foods to be baked are arranged between the baking surface and the upper heating means; said lower and/or upper heating means of the chambers being, in use, supplied by a predetermined rated power that can be provided by a source of electrical energy; a control unit connected to the lower and/or upper heating means of each chamber and configured to divide said rated power into respective pre-assigned power portions and supplied to each chamber; characterised in that the control unit is configured to receive a selection signal of at least one of said chambers, defined as a superpower chamber, regardless of a detection of exceeding the total power required by the chambers with respect to said predetermined rated power, wherein said selection signal is representative of an operating demand at a superpower value that is greater than the power portion value pre-assigned to the chamber; said control unit being configured to: - calculate the difference between the superpower value demanded and the power portion value pre-assigned to the chamber; - calculate a total value of instantaneous power unused by the heating means for heating at least part of the remaining chambers with respect to respective pre-assigned power portions; - divert at least a part of said unused instantaneous power value towards the heating means for heating said superpower chamber; said control unit being configured to include a manual mode wherein it receives the selection signal from an operator via a communication interface on how much and which unused instantaneous power to divert towards said superpower chamber; alternatively, said control unit being configured to include an automatic mode in which said selection signal is automatically generated according to predefined values of unused instantaneous power. a plurality of baking chambers for baking foods each comprising a baking surface on which foods to be baked are positioned; each of said chambers comprising lower heating means, of an electrical type, arranged below the baking surface, and/or upper heating means, of an electrical type, arranged above the baking surface and distanced therefrom by a predefined distance so that the foods to be baked are arranged between the baking surface and the upper heating means; said lower and/or upper heating means of the chambers being, in use, supplied by a predetermined rated power that can be provided by a source of electrical energy; a control unit connected to the lower and/or upper heating means of each chamber and configured to divide said rated power into respective pre-assigned power portions and supplied to each chamber; characterised in that the control unit is configured to receive a selection signal of at least one of said chambers, defined as a superpower chamber, regardless of a detection of exceeding the total power required by the chambers with respect to said predetermined rated power, wherein said selection signal is representative of an operating demand at a superpower value that is greater than the power portion value pre-assigned to the chamber; said control unit being configured to: - calculate the difference between the superpower value demanded and the power portion value pre-assigned to the chamber; - calculate a total value of instantaneous power unused by the heating means for heating at least part of the remaining chambers with respect to respective pre-assigned power portions; - divert at least a part of said unused instantaneous power value towards the heating means for heating said superpower chamber; - calculate the difference between the superpower value demanded and the power portion value pre-assigned to the chamber; - calculate a total value of instantaneous power unused by the heating means for heating at least part of the remaining chambers with respect to respective pre-assigned power portions; - divert at least a part of said unused instantaneous power value towards the heating means for heating said superpower chamber; said control unit being configured to include a manual mode wherein it receives the selection signal from an operator via a communication interface on how much and which unused instantaneous power to divert towards said superpower chamber; alternatively, said control unit being configured to include an automatic mode in which said selection signal is automatically generated according to predefined values of unused instantaneous power.
