Sanitary device including a cold water recovery buffer tank.

Abstract

The invention relates to a sanitary device comprising: - a hot water inlet (1), a cold water inlet (2), - a mixer (4) normally mixing the hot and cold water simultaneously, - a buffer tank (5), - a temperature sensor (8) for measuring the water temperature at the hot water inlet (1), - solenoid valves (EVi) arranged and controlled such that: -- when the measured temperature satisfies at least one predefined condition, the water from the hot water inlet is directed to the tank, -- when at least one predefined condition is met, the tank is drained by directing the water it contains to the mixer, characterized in that the solenoid valves are further arranged and controlled to, during the draining of the tank, cut off all fluid communication between the tank and the inlets.
