DHW CylinderactoSTOR VIH K 300

Compact design with impressive DHW capacity and flow rate.

Fast, energy-efficient domestic hot water heating
Compact domestic hot water supply for up to 10 people
Maintenance‑free cylinder thanks to impressed current anode
Greater energy savings by utilising the condensing effect

The actoSTOR shift‑load technology combines the benefit of having a domestic hot water reserve – capable of delivering a large volume of hot water in a short time – with the ability to maintain a constant flow once the reserve is depleted. All of this comes in a compact, attractive design that fits perfectly into your home. With actoSTOR, you’ll never run out of hot water. These cylinders are the ideal partner for Vaillant combi boilers, providing long‑lasting comfort and allowing the hot water reserve to be replenished much faster than with a standard heat exchanger tank. Their robust construction, backed by carefully selected materials, Vaillant’s high production standards, and an integrated impressed current anode, ensures the tank remains free from corrosion and wear.
