at least one temperature sensor (T2) is provided in the recirculation line (20), and
the system comprises a control unit (2) with:
an interface (402) for inputting at least one temperature value relative to the desired supply temperature of hot water;
a comparing section (702) with at least one input for said at least one water temperature sensor (T2) in the recirculation line or network (20);
a unit (602) generating and transmitting the command actuating at least one valve (V2) closing/opening the recirculation circuit (20),
and which control unit controls said at least one valve (V2) in order to keep the recirculation line or network (20) open during the step supplying hot water till the water temperature inside said recirculation line or network (20) drops below a predetermined threshold temperature lower by a given value than the set supply temperature.
