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

Thanks to the optimal connection accessories and the option to cover the connecting pipes with additional design elements, it also looks great in the kitchen or bathroom. With a storage capacity of 72 liters, it's ideal for smaller households.
