Multi-Functional Buffer CylinderallSTOR plus VPS 300 - 2000l

Multi-functional buffers designed to fit perfectly into homes and apartment buildings.

A future-proof high-capacity heat reserve
The principle of stratification for greater energy efficiency
Efficient integration of solar energy
Hygienic hot water preparation
Hardly any heat loss

With our highly insulated allSTOR plus multi-function buffer cylinder, there are virtually no limits to your home comfort. Designed to create a large, efficient heat reserve, it supports both domestic hot water and central heating and can be combined with any type of heat generator, whether fossil-based or renewable. With capacities ranging from 300 to 2000 litres, it meets the needs of everything from single-family homes to multi-family properties. allSTOR plus can be paired with dedicated distribution modules for heating or domestic hot water: the aguaFLOW station prepares hygienic hot water on demand, with the buffer water never coming into direct contact with your drinking water.
