Assembly distributor IVAR.CI 557 KS, 7-way

Product detailed description

This 7-way floor heating distributor is commonly used in underfloor heating systems in residential and commercial buildings. It is designed for integration into hydronic heating systems where multiple loop circuits are required for even heat distribution across large floor areas. The unit is typically installed in mechanical rooms or utility areas where access for maintenance and inspection is possible. The integrated circulation pump ensures consistent flow across all connected loops, supporting balanced system performance and thermal comfort.

Installers working with radiant floor heating systems often encounter the need to manage multiple heating loops, especially in larger or multi-room installations. The IVAR.CI 557 KS provides a compact solution for distributing heated water to seven separate circuits, each of which can be individually controlled or monitored. The nominal pressure rating of PN 6 ensures compatibility with standard heating system pressures and supports reliable operation under typical operating conditions.

Technical parameters

Installation and connection

The IVAR.CI 557 KS is installed using standard pipe connections, with inlet and outlet ports for the main heating circuit and individual ports for each of the seven floor heating loops. The connection sizes and thread types must be verified according to the manufacturer’s technical documentation to ensure correct fitting and sealing. During installation, it is essential to align the distributor correctly and secure it to prevent vibration or movement that could affect the integrity of the connections.

Common installation mistakes include incorrect orientation of the unit, improper sealing of the ports, and failure to ensure that all connections are tightened to the recommended torque. It is also important to check that the integrated pump is correctly wired and that the electrical supply is compatible with the system’s requirements. Before commissioning, the system should be flushed and tested for leaks to ensure reliable operation.

Compatibility and accessories

The IVAR.CI 557 KS is compatible with standard underfloor heating systems that use water as the heat transfer medium. It is typically used in conjunction with floor heating manifolds, thermostats, and control valves to manage the flow and temperature of each circuit. Additional components such as balancing valves, pressure gauges, and temperature sensors may be required to achieve optimal system performance.

When installing the distributor, it is important to ensure that the piping and fittings used are compatible with the nominal pressure rating of PN 6. The system should also be designed to accommodate the flow requirements of the integrated pump, ensuring that all loops receive adequate circulation. No related products are listed for this model.

Technical background for designers

The IVAR.CI 557 KS operates by distributing heated water from a central heating source to multiple floor heating loops. The integrated circulation pump ensures that water flows evenly across all connected circuits, maintaining consistent heat output and thermal efficiency. The distributor is constructed from materials that are resistant to corrosion and thermal expansion, ensuring long-term reliability in hydronic systems.

The performance of the distributor is influenced by factors such as the total number of loops, the length and diameter of the piping, and the overall system pressure. Proper sizing of the distributor and pump is essential to avoid overloading the system or creating imbalances in heat distribution. The PN 6 rating ensures that the unit can handle the typical pressures encountered in underfloor heating systems, making it suitable for use in both residential and commercial applications.

Service and operation

Regular inspection of the IVAR.CI 557 KS is recommended to ensure that all connections remain secure and that the pump is operating efficiently. The system should be checked for signs of leaks, blockages, or unusual noise, which may indicate the need for maintenance. No specific service intervals are provided in the technical documentation, but it is advisable to follow the manufacturer’s guidelines for periodic checks and cleaning.

During operation, the distributor should be monitored for consistent flow and temperature across all loops. If imbalances are detected, adjustments to the balancing valves or pump settings may be necessary. The unit should be kept free from debris and moisture to prevent damage to the internal components and ensure long-term performance.
