automatic recirculation water and method of operation

The object of the present invention relates to a new automatic system that interconnects the cold water circuits and domestic hot water (DHW), so that the demand (user) ACS system recirculates the cold water in the pipe and hot water supplied by the boiler until the hot water temperature is the predetermined, fully automatically. The system automatically stops the recirculation if the user interrupts the demand before the ACS reaches the predetermined or if the hot water temperature is not reached in a suitable time (which can be preset in each set) temperature. The system can communicate with home automation systems of the building. # This allows the system to be used in installations of domestic and industrial water.
