Patent ID: 8107804

Claim:
An energy accumulator system for accumulating heat from a heat source for subsequent supply to a heat demand, comprising: an energy accumulator having a storage material adapted to be physically separated and in a heat-exchange relation with a fluid from the heat source so as to store heat produced by the heat source, the storage material and the fluid being different; a controller connected to the energy accumulator to obtain temperature data with respect to the storage material, and to the heat source so as to selectively actuate the heat source; an energy level calculator associated with the controller, the energy level calculator determining a storage capacity in the energy accumulator as a function of temperature data of the storage material; and an operation identifier associated with the controller, the operation identifier determining when to store energy in the energy accumulator as a function of the storage capacity and of condition data pertaining to the heat source; whereby the controller actuates the energy accumulator and the heat source to store heat in the energy accumulator.
