1. A method for determining the thermal consumption of an energy system, wherein the energy system generates a total thermal energy within a time range, the method comprising:
determining a thermal charging energy of the energy unit within the time range;
determining a thermal discharging energy of the energy system within the time range; and
calculating a resulting thermal consumption within the time range by adding the total thermal energy to a difference between the ascertained thermal discharging energy and the ascertained thermal charging energy;
wherein the energy system includes a heat transfer medium within a thermal network, the heat transfer medium transported between a multiplicity of heat exchange elements and at least one thermal energy storage unit; and
determining the thermal charging energy of the energy system and the thermal discharging energy of the energy system includes consideration of a volume flow rate and a temperature of the heat transfer medium within the energy system.
