Multi-Functional Buffer CylinderallSTOR exclusiv VPS 300-2000l

The multi-functional buffer cylinder for detached and semi-detached houses.

A future‑proof, high‑capacity heat reserve
Efficient integration of solar energy
Hygienic hot water preparation
Hardly any heat loss
Suitable for cascade connections

With our highly insulated multi‑function buffer cylinder allSTOR exclusive, there are virtually no limits to your home comfort. Designed to create a large heat reserve, it is suitable for both domestic hot water and central heating preparation. It can be combined with any type of heat generator – whether fossil‑fuelled or renewable. Available in capacities from 300 l to 2000 l, it meets almost every demand in single‑ or two‑family homes. The allSTOR exclusive can be paired with two dedicated modules to distribute heating or domestic hot water throughout your home: the domestic hot water station aguaFLOW, designed for hygienic water preparation, and the solar charging station auroFLOW, which collects free heat from a solar system.
