Patent ID: 8636226

Claim:
A method for estimating the fuel supply of a boiler, for a building having a boiler and energy accumulation means, in order to ensure a desired indoor temperature during an autonomy period P, this method including the following steps: a) making an estimation, by a data processing device based on received temperature data, of the average outdoor temperature during the autonomy period P, the autonomy period P being a predetermined period of time during which the boiler and accumulation means will continue to function to ensure the desired indoor temperature without requiring additional fuel to be loaded into the boiler, b) said data processing device determining an energy consumption of the building in order to ensure said desired indoor temperature from the previous estimation of the average outdoor temperature, c) said data processing device determining the amount of energy to be provided depending on the previous consumption, and said data processing device determining the amount of fuel required for the boiler for providing said amount of energy, wherein step c) at least takes into account: a heating autonomy at the beginning of the period P, the heating autonomy being the time during which energy available in the accumulation system is able to meet heating needs of the building, the maximum amount of energy which may be stored in the accumulation means, the minimum amount of energy which may be loaded into the boiler, and the maximum amount of energy which may be loaded into the boiler.
