Manifold assembly - without cabinet, 1" x EC, 2-way

Product detailed description

This manifold assembly is commonly used in residential and commercial buildings for radiator heating systems. It provides a central distribution point for heating circuits, allowing for balanced flow and efficient temperature control. Installers typically use this unit in systems where separate pump installation is not required, as the boiler provides the necessary circulation. The unit is particularly suited for systems with a temperature drop of +75°C / +65°C in the radiator section.

The design supports integration with standard heating systems and allows for multiple parallel circuits. It is important to ensure the system is thoroughly flushed before commissioning, especially when combining radiator and floor heating. This helps prevent blockages and ensures long-term performance. The unit is constructed using nickel-plated brass, which offers resistance to corrosion and mechanical wear.

The 50 mm spacing between outlets is critical for proper fitting and alignment of connecting pipes. The 1 inch female inlet and 3/4 inch EK outlets allow for flexible connection to standard pipe sizes. The PN 10 rating indicates suitability for low-pressure systems, while the maximum operating temperature of +120°C ensures compatibility with conventional heating applications.

Installation and connection

To install the manifold assembly, first position it in a location that allows for easy access to all connections and ensures proper drainage. Secure the unit using the included mounting brackets to prevent movement during operation. Connect the 1 inch female inlet to the main supply line using appropriate fittings and sealants. Attach the 3/4 inch EK outlets to individual heating circuits, ensuring that each connection is tightened securely and checked for leaks. A common mistake is neglecting to align the outlets correctly before tightening, which can lead to stress on the manifold body. Always verify that all connections are perpendicular to the manifold surface and that the sealing material is evenly distributed. Before final tightening, rotate the fittings slightly to ensure the sealing surfaces seat properly.

Compatibility and accessories

This manifold is compatible with standard radiator heating systems and plumbing installations where a pump is not required. It works well with copper, PEX or steel piping and supports integration with thermostatic radiator valves. To complete the installation, additional components such as insulation, pipe clamps and expansion tanks may be required depending on the system design.

Technical background for designers

The unit operates by distributing heated water through individual circuits via the distributor and collecting the return flow through the collector. The nickel-plated brass construction offers good thermal conductivity and resistance to chemical attack from water. The design allows for even flow distribution, reducing the risk of thermal imbalance in the system. Longevity depends on maintaining clean water conditions and avoiding excessive pressure fluctuations.

Service and operation

Regular checks should focus on the integrity of all connections and the condition of sealing materials. Any signs of leakage should be addressed immediately to prevent damage to surrounding structures. The unit does not require scheduled servicing unless issues arise from system contamination or improper installation.

Frequently asked questions

Can this manifold be used with a floor heating system?
Yes, it can be used with floor heating provided the system is designed with a separate circuit and the return line is properly insulated to avoid thermal interference.

What is the maximum number of circuits supported?
The number of circuits depends on the selected manifold length. Refer to the manufacturer’s table for recommended lengths based on the number of outputs needed.

Is it possible to install the manifold in a vertical position?
While horizontal installation is preferred, vertical mounting is acceptable provided all connections remain accessible and the system allows for proper drainage.

Can the unit be used with a boiler that has a built-in pump?
Yes, the unit is designed for use with boilers that provide circulation. A separate pump is not required for normal operation.
