Expansion vessel for Central Heating IBAIONDO 100L

Product detailed description

Expansion vessels are essential components in closed central heating systems, ensuring stable pressure and accommodating thermal expansion of the fluid. This 100L model is suitable for medium to large residential and commercial installations, including multi-family buildings and industrial facilities with hydronic heating systems. Installers commonly use such vessels in systems where pressure fluctuations must be controlled to prevent damage to components like pumps, valves and radiators. The vessel is designed for floor-standing installation, allowing it to be placed directly on the floor without requiring wall mounting or additional supports.

Proper sizing and positioning of expansion vessels are critical for system performance. The vessel must be selected based on the system’s volume, operating pressure and temperature range. It should be installed as close as possible to the boiler or heat source to ensure effective pressure regulation. The vessel must also be accessible for inspection and maintenance, and its location should avoid exposure to freezing conditions or excessive heat.

Technical parameters

Installation and connection

Installation begins with verifying the system’s pressure settings and ensuring the vessel’s pre-charge pressure is adjusted accordingly. The 1 inch connection requires a compatible pipe or fitting with the same thread type. The vessel should be installed in a vertical position with the connection pointing upwards to allow for proper air and water separation. A pressure gauge and bleed valve are typically installed nearby for monitoring and maintenance. Common mistakes include incorrect pre-charge pressure settings, improper orientation of the vessel and failure to secure the vessel on a stable, level surface.

Compatibility and accessories

This expansion vessel is compatible with central heating systems that operate within the specified pressure and temperature ranges. It is designed to work with standard central heating components such as boilers, circulators and pressure-reducing valves. No additional accessories are included in the standard package, but a pressure gauge and bleed valve are often required for system monitoring and maintenance. Installers should ensure that all system components are compatible with the vessel’s specifications before installation.

Technical background for designers

The IBAIONDO 100L expansion vessel operates on the principle of separating heated water from compressed air using a fixed EPDM membrane. This membrane is resistant to thermal expansion and contraction, ensuring long-term stability and preventing contamination of the system water. The vessel is constructed from powder-coated steel with a 1 mm wall thickness, providing durability and resistance to corrosion. The EPDM membrane is particularly suited for use in central heating systems due to its flexibility and resistance to heat and water. The vessel’s integration into the system depends on the system’s pressure and temperature characteristics, and its performance is influenced by the accuracy of the pre-charge pressure setting and the quality of the installation.

Service and operation

Regular checks of the vessel’s pressure and membrane integrity are recommended to ensure continued performance. The pre-charge pressure should be verified periodically and adjusted if necessary to maintain system stability. The vessel should be inspected for signs of corrosion, leaks or damage to the membrane. No specific service intervals are provided, but it is advisable to perform checks during routine system maintenance. If the vessel shows signs of failure, such as excessive pressure fluctuations or water leakage, it should be replaced immediately to prevent damage to the system.

Frequently asked questions

Can the IBAIONDO 100L be connected to a central heating system with a pressure higher than 6 bar?
No, the vessel is rated for a maximum working pressure of 6 bar. Connecting it to a system with higher pressure could cause damage or failure.

Is it possible to adjust the pre-charge pressure after installation?
Yes, the pre-charge pressure can be adjusted using the included valve. It should be set to match the system’s minimum operating pressure for optimal performance.

Can this expansion vessel be used in a cooling system?
Yes, the vessel is suitable for both heating and cooling systems, provided the operating temperature and pressure are within the specified range.

What is the expected service life of the EPDM membrane?
The membrane is designed for long-term use, but its lifespan depends on the system conditions. Regular checks are recommended to ensure it remains intact and functional.
