The auroSTOR/uniSTOR plus/exclusive product family consists of indirect hot water cylinders characterised by a clear design along with user- and eco-friendliness. With capacities of up to 500 litres and variable configurations, they enable the storage of excess energy as thermal energy produced by solar systems or heat pumps. The clearly arranged user interfaces display important figures such as the water temperature, as well as information about the charge level and system connectivity for the LED variant.
