Vaillant´s auroSTEP pro system contains of a storage which is installed on the roof directly above the collector/s. Well crafted collectors, enameled “tank-in-tank” storages and a coated mounting bracket give the system the known Vaillant quality.
The storages are available in the capacities of 150, 200 and 300 litres of domestic hot water.
When the solar earnings are not sufficient to cover the warm water demand, electrical backups of 2 or 3 kW can be added to the system. You can obtain further warm water comfort without great installation efforts.
