Expansion vessel for central heating Hydroland IBAIONDO 24 L NP.CO.24.IB

Hydroland IBAIONDO 24 L expansion vessel is a diaphragm-type accumulator designed for closed central heating systems. With a nominal capacity of 24 litres, it reduces pressure fluctuations caused by thermal expansion and helps maintain system stability. The diaphragm separates the water from the pre-charged air cushion, providing consistent pressure regulation and preventing frequent cycling of pumps and safety valves.

Advantages

The diaphragm construction ensures reliable separation of water and air, reducing the risk of waterlogging and corrosion. Its 24-litre capacity is suitable for many residential and small commercial heating circuits, delivering predictable pressure management without occupying large space. The vessel's compact design and standard connection type allow straightforward installation on return or supply lines. Built for routine operation, it supports longer component life by reducing strain on pumps, valves and other hydraulic elements.

Suitable for

• Residential central heating systems
• Small commercial heating circuits
• Closed hot-water heating installations with limited expansion volume
• Systems requiring pressure stabilization and protection of pumps and valves

Key specifications

• Type: Diaphragm (bladder) expansion vessel
• Nominal volume: 24 litres
• Function: Absorbs thermal expansion and stabilizes system pressure
• Mounting: Inline installation on heating circuit (return or supply)
• Separation: Physical diaphragm separating water and pre-charged air

How to use

Install the expansion vessel on the heating circuit according to system layout and local regulations, typically on the return line near the boiler or pump group. Pre-charge the air side to the recommended pressure for the specific heating system and verify the water side is at ambient pressure before commissioning. After installation, monitor system pressure during initial heat cycles and adjust the pre-charge if necessary to achieve correct operating pressure and prevent frequent activation of safety devices.

Usage recommendations

Check the pre-charge pressure periodically and before seasonal start-up. Inspect for signs of leaks, corrosion or loss of diaphragm function and replace the vessel if performance deteriorates. Use the vessel within its intended application range: closed hot-water heating systems where a 24-litre nominal volume meets the system's expansion needs.
