Abstract: A sanitary water storage device configured to store and supply sanitary hot water includes a housing with a first reservoir and a second reservoir. A volume of the first reservoir and a volume of the second reservoir are modifiable proportionally to each other. A water distributing means includes an inlet, a first outlet and a second outlet, which first outlet is in liquid connection with the first reservoir and the second outlet is in liquid connection with the second reservoir. Depending on a liquid temperature measured at the inlet, the water distributing means is configured to to bring the inlet into liquid connection with the first outlet or the second outlet.
