300 L DHW Cylinder with Integrated Buffer Volume
This combination unit offers more domestic hot water storage than the 200 L version while adding 100 L of buffer volume to the system. It is suited to projects with higher hot water demand and a need for smoother system operation.
XL Heat Exchanger for Stronger Hot Water Production
The 30 m AISI 316L heat exchanger helps the heat pump transfer energy efficiently to the domestic water. Together with the integrated buffer volume, it supports more stable heat pump operation.
Compact Solution for Combined Functions
By combining hot water storage and buffer volume in one black stainless steel unit, the installation remains clearer, more compact and professionally finished.

| Safety requirements |
| The storage vessel must be protected against overpressure at all times. We recommend installing the following safety accessories: * Safety valve and inlet combination * Nexus sanitary expansion vessel * Nexus expansion vessel for heating systems The required expansion vessel capacity must be calculated according to the total system volume and operating conditions. |
