Heatrae Sadia 95612723 200 Litre 6 Bar Expansion Vessel – Genuine Commercial Spare

Genuine Heatrae Sadia 95612723 200 Litre 6 Bar Expansion Vessel

The genuine Heatrae Sadia 95612723 Expansion Vessel is a 200 litre, 6 bar-rated vessel designed for use with selected Megaflo Flexistor, commercial calorifier and industrial hot water storage systems.

Expansion vessels play a critical role in sealed hot water systems by accommodating water expansion as temperatures rise. This helps maintain stable system pressure and protects associated components from excessive pressure build-up.

Manufactured to original Heatrae Sadia specifications, this genuine commercial replacement vessel is designed for demanding hot water installations across commercial, industrial and large-scale building applications.

What Does an Expansion Vessel Do?

As water heats, it expands. In sealed systems, an expansion vessel absorbs this increase in volume to help:

• maintain safe operating pressure
• reduce stress on system components
• protect valves and pipework
• improve overall system stability
• support efficient hot water operation

A failing expansion vessel can cause:

• pressure fluctuations
• discharge from relief valves
• system over-pressurisation
• noisy operation
• repeated pressure loss issues
