Abstract

In a domestic environment (DA) there is present a hot-water distribution system (HW) to which there is connected at least one electrical household appliance (WM, DW). The hot water is introduced into the distribution system (HW) by means of a respective supply apparatus (HWS), and the operating cycle of the electrical household appliance (WM, DW) entails the use of a working amount of hot water at a working temperature. The control system (SC1) of the electrical household appliance is operative for:
  • a) detecting the value of the temperature of the water available in the first distribution system (HW);
  • b) drawing into the electrical household appliance (WM, DW) a mass of hot water compatible with the temperature and the working amount associated to the operating cycle selected for the electrical household appliance (WM, DW);
  • c) modifying the operating cycle of the electrical appliance (WM, DW) according to the amount of heat introduced into the appliance itself, understood as the product of the mass and the temperature of the water taken in by the distribution system (HW).
