Easy monitoring of water temperature

Our hot water cylinders auroSTOR plus VIH S provide high hot water comfort and efficiency in combination with solar thermal. Its technology allows it to fully take advantage of the benefits of free solar heat. With its 300 - 500 L it is the ideal solution for 1- or 2-family houses ensuring perfect domestic comfort even in case of simultaneous multiple withdrawals. Because of its B-rated insulation technology on a scale of A to F, heat loss remains quite low. Made of high quality, protected against corrosion by a replaceable magnesium anode, it stands out for reliable operation for many years.

Ideal for:
