Manifold/collector assembly - for underfloor heating - without cabinet - 1 "xEK; 3-way; brass IVAR.CS 553 VP

Product detailed description

Underfloor heating systems require precise flow distribution and return collection to ensure even heat distribution across the floor surface. This manifold/collector assembly is commonly used in residential and commercial buildings where hydronic underfloor heating is integrated with other heating methods. Installers working on mixed systems involving radiators and underfloor heating must ensure compatibility and balanced flow rates. The brass construction provides corrosion resistance and durability, making it suitable for long-term operation in heating systems with closed-loop water circulation.

When installing this unit, it is essential to consider the system's hydraulic balance and the need for regular maintenance. The assembly includes components such as flow-regulating valves, shut-off valves, and pressure relief features to support efficient operation. The absence of an enclosure allows for flexible mounting options, either wall-mounted or in a custom housing, depending on the system layout and space constraints.

Technical parameters

Operating temperature	+90 °C
Nominal pressure	PN 10
Code	553971BS
Brand	IVAR

The operating temperature of +90°C and PN 10 pressure rating are critical for determining the suitability of this manifold for specific heating systems. These parameters ensure compatibility with standard underfloor heating circuits and allow for integration with conventional heating systems that operate within similar temperature and pressure ranges. The CW617N brass material is selected for its resistance to corrosion and mechanical strength under thermal cycling.Installation and connection The manifold is connected using 1 inch external connections, typically threaded for secure and leak-free installation. When mounting, ensure the unit is level and that all pipe connections are aligned to prevent stress on the fittings. The included mounting brackets should be used to secure the manifold to the wall or floor. During installation, verify that all valves are in the closed position and that the system is free of debris before commissioning. A common mistake is failing to purge the system of air before operation, which can lead to inefficient heat transfer and potential damage to components.Compatibility and accessories This manifold is compatible with standard underfloor heating systems using water as the heat transfer medium. It is intended for use with copper or PEX piping and requires additional components such as a circulation pump and control system for full functionality. Accessories such as pressure gauges, expansion vessels, and balancing valves may also be required depending on the system design. Related products include IVAR manifolds with built-in pumps or enclosures for different installation scenarios.Technical background for designers The manifold operates by distributing heated water through multiple circuits and collecting the cooled return water for reheating. The CW617N brass material offers good thermal conductivity and mechanical strength, ensuring reliable operation under thermal cycling. The design allows for individual circuit balancing using the flow-regulating valves, which helps optimise system efficiency. The longevity of the unit depends on the quality of the water in the system and the presence of protective additives to prevent corrosion and scaling.Service and operation Before commissioning the system, it is essential to flush the entire heating system to remove any debris or contaminants that could cause blockages or damage. The manufacturer recommends using a system treatment such as GEL.LONG LIFE 100 to extend the service life of the components. During operation, check for leaks and ensure that all valves function correctly. Regular inspection of the pressure gauge and temperature readings can help identify potential issues early.Frequently asked questions

Can this manifold be used with a combination of underfloor heating and radiators?
Yes, it can be used in mixed systems provided the system is balanced and the operating parameters match the manifold's specifications.

What is the recommended method for purging air from the system?
Air should be purged manually using the automatic air vents included in the manifold assembly before the system is put into operation.

Is it necessary to use a circulation pump with this manifold?
Yes, a circulation pump is required to ensure proper flow through the heating circuits and maintain system efficiency.

Can the manifold be mounted without an enclosure?
Yes, the unit is designed for installation without an enclosure, but it can be combined with a custom housing if required for the specific application.
