Sunex Fish S4 X water buffer tank – 100 liters

Product overview

The Sunex Fish S4 X is a 100-liter buffer storage tank for vertical operation. It is available in wall-mounted or floor-standing versions and was specifically designed for use in modern heating systems.

Ideally suited for all types of heating systems, especially in combination with heat pumps. The buffer tank allows the connection of a heat source circuit as well as a central heating circuit, thus optimizing system operation.

function & Temperature range

The storage unit serves as an intermediate storage point for thermal energy to shift loads and adjust the output of heating systems. It can also be used for cooling: storage of cooling water at temperatures between 7 and 12 °C is possible.

The buffer tank is designed exclusively for vertical installation. When installing, ensure a stable base or suitable mounting system and allow sufficient space for connections and maintenance.

Advantages

The Sunex Fish S4 X improves the efficiency of heating and cooling systems by buffering thermal energy, reducing start/stop cycles of the heat source and ensuring more consistent flow temperatures.
