## Description

**Heating expansion tank GWS HWB12LX, 12 L** is a GWS HeatWave expansion vessel for sealed heating systems. It takes up the water that expands as it heats and keeps the system pressure below the point where the safety valve opens.

Key specifications: 12 L volume, steel body, working pressure up to 6 bar and water temperature up to 99 °C.

### Where to use it

- a sealed heating system holding up to about 110 L of water
- a boiler of roughly up to 8 kW with radiators
- installation on the return pipe before the circulation pump

Do not fit a shut-off valve between the vessel and the system unless it is protected against accidental closing.
