Abstract

The present invention refers to a mixing system associated to an accumulation system which allows water savings in domestic water installations. When hot water is required at the valve exit (13), but no hot water is available at the valve inlet (11), the cold or partially water entering the mixing valve through the hot water entry (11) of the mixing valve goes to the accumulation reservoir (14), where it remains stored under pressure, until the hot water reaches the inlet (11) of the mixing valve or the accumulation reservoir (14) is filled with water. Only when hot water exists at the inlet (11) of the mixing valve, or when the accumulation reservoir (14) is charged with water, the water entering the valve through inlet (11) is conducted towards the mixing valve discharge (13). While water exists inside the accumulation reservoir (14), this is conducted towards the cold water inlet (12) of the mixing valve preferably to the cold water (19) coming from the main cold water distribution system, thus allowing potable water savings. Present invention applies in the construction industry, and more precisely in domestic water installation systems.
