Volumisers

Benefits

• Safe pressure management: Prevents system damage in large or complex heating installations.
• System protection: Extends the lifespan of boilers, valves, and pipework.
• High efficiency: Maintains stable water pressure and optimal heating performance.
• Durable construction: Designed for long-term reliability in demanding systems.
• Versatile application: Suitable for domestic and commercial unvented cylinder systems.

Applications

• Large unvented hot water cylinders and multiple cylinder setups.
• Sealed central heating systems.
• Domestic and commercial boiler installations requiring high capacity expansion vessels.
• Systems with high water volume or renewable energy integration.

Key Features

• Robust steel construction with corrosion-resistant coating.
• Flexible diaphragm or bladder to absorb water expansion.
• Pre-charged with air or nitrogen for immediate pressure balance.
• Available in multiple volumes to suit different system sizes.
• Complies with UK Building Regulations and EN 13831 standards.

Performance & Maintenance

Voluminers Expansion Vessels require periodic inspection to check diaphragm integrity and air charge. Properly maintained, they provide long-lasting pressure regulation, protecting the system from over-pressurisation and ensuring consistent hot water and heating performance.
