Manifold/collector assembly - for underfloor heating - without cabinet - 1 "xEK; 11-way; brass IVAR.CS 553 VP

Product detailed description

Underfloor heating systems in residential and commercial buildings require precise control over heat distribution. This manifold assembly provides a central point for regulating flow in each circuit. It is commonly used in new builds and renovations where multiple heating zones are required. Installers and technicians working on radiant floor heating systems will find this unit suitable for integration with standard heating circuits and compatible with various control strategies.

The unit is designed for use in hydronic heating systems where accurate flow management is essential. It is particularly useful in systems where zoning is required to maintain comfort and efficiency. The brass construction ensures durability and resistance to corrosion, making it suitable for long-term use in wet environments.

Technical parameters

Installation and connection

Installation requires connecting the manifold to the heating system using 1-inch external thread connections. The assembly includes mounting brackets for secure installation. It is important to verify that all connections are tightened to the correct torque to prevent leaks. Common installation mistakes include incorrect thread sealing or misalignment of the manifold with the heating circuits. Ensure that the system is fully drained and flushed before commissioning.

Compatibility and accessories

This manifold is compatible with standard underfloor heating systems using polyethylene or PEX piping. Additional components such as circulation pumps, thermostats, and insulation boards may be required depending on the system design. Accessories such as mounting brackets and sealing compounds are included in the package. Related products such as expansion vessels and balancing valves should be considered for complete system functionality.

Technical background for designers

The manifold operates by distributing heated water to individual circuits and collecting return water for reheating. The brass material offers good thermal conductivity and resistance to scaling. The PN10 rating ensures that the unit can handle standard domestic heating pressures. The design allows for even distribution of flow, which is essential for maintaining consistent heat output across the floor area. System efficiency is affected by correct balancing and the quality of insulation around the manifold and piping.

Service and operation

Regular maintenance includes checking for leaks and ensuring that all valves operate smoothly. The automatic air vent and drain valve help maintain system efficiency. It is recommended to flush the system periodically to remove debris and prevent blockages. The unit should be inspected for signs of corrosion or wear, particularly at connection points. The manufacturer recommends using a system treatment such as GEL.LONG LIFE 100 to extend service life.

Frequently asked questions

Can this manifold be used with a combination of underfloor heating and radiators?
Yes, it is suitable for mixed systems. However, it is important to follow the manufacturer's instructions for system flushing and balancing.

Is the manifold compatible with thermostatic controls?
Yes, the flow control valves allow for integration with thermostatic systems to manage individual circuit temperatures.

What sealing compound should be used for the 1-inch connections?
Use a sealing compound suitable for brass fittings and compatible with the system media as specified by the manufacturer.

Can the manifold be mounted in a suspended ceiling?
Yes, provided that the mounting brackets are securely fixed and the installation allows for access to all valves and controls.
