The compact storage tank operates with exceptional efficiency thanks to our patented ActoNomic stratified charging system. It continuously heats small amounts of water and stratifies them from the top into the tank. This means hot water flows from the tap faster – and you enjoy maximum hot water comfort. Stratified storage tanks deliver up to 50% more performance than conventional coil storage tanks of the same volume. The actoSTOR is technically and aesthetically perfectly matched to the modern ecoTEC plus VCW 1-5 gas condensing boiler with integrated hot water preparation.

Thanks to its optimal connection accessories and the option of cladding the connecting pipes with additional design elements, it also looks great in the kitchen or bathroom. With a storage capacity of 72 liters, it is ideally suited for smaller households.
