Heating Vessels

Heating vessels accommodate the expansion which takes place within closed heating and hot water systems when the water is heated. Since the volume of water goes up by approximately 4.5% when heated from 0°C to 100°C, the heating vessel accommodates this additional increase in pressure, allowing the system to continue to function normally. 

When water temperature goes up, the membrane inside the heating vessel expands so that water may enter the vessel, thereby relieving the overall pressure.

At Plumbing Superstore, we offer a constantly growing range of heating expansion vessels from market leaders like RWC (Reliance Water Controls), Zilmet and Altecnic. Manufactured from top-quality materials to high industry standards, our tanks come in a huge range of sizes, from 2 litres to over 800 litres for some models. A highly versatile, reliable and durable solution, they’re suitable for use across various domestic and industrial applications.
