Abstract: Method for controlling the distribution of thermal energy in a commercial or industrial entity having a waste heat producing circuit connected to a primary side of a heat exchanger whose secondary side is connected to a heat recovery unit (HRU). To the heat sink side of the HRU a heat consuming circuit is connected. The method determines a first temperature range at which the waste heat producing circuit is operable at its optimal Energy Efficiency Ratio. Determines a second temperature range between a predetermined upper limit temperature and a predetermined lower limit temperature using the first temperature range and the heat exchange capacities of the heat exchanger and the HRU such that the waste heat producing circuit can be stably operated at its optimal Energy Efficiency Ratio (EER). And controls the fluid temperature in the return line by means of controlling one or more flow valves installed at the least at one or more heat energy consumer such that the temperature in the return line does not exceed the predetermined upper limit temperature neither fall below the predetermined lower limit temperature.
