Manifold / Distributor Comap Belka 11 outlets, supply 1" — return 1/2"

Comap Belka hydraulic manifold with 11 outlets provides centralized distribution and return for heating systems. Designed for installations that require multiple branch lines, this manifold has a 1" supply connection and eleven 1/2" return outlets, enabling a neat and compact piping layout for underfloor heating or multi-zone radiator circuits. The unit supports organized flow management and simplifies connection of several circuits to a single supply and return header.

Advantages

The Comap Belka manifold groups multiple heating circuits in one assembly, reducing installation complexity and saving space in the plant room. Its combination of a 1" supply inlet and 1/2" outlet ports allows consistent hydraulic distribution across up to eleven circuits while keeping individual branch connections standard-sized for common fittings. The compact design facilitates mounting and maintenance, and the clearly separated supply and return sides simplify system balancing and inspection.

Suitable for

• Underfloor heating systems with multiple zones
• Multi-zone radiator installations requiring centralized manifolding
• Small commercial or residential central heating plant rooms
• Renovation projects where compact distribution headers are needed

Key specifications

• Number of outlets: 11
• Supply connection size: 1 inch
• Return connection size: 1/2 inch (per outlet)
• Function: hydraulic distribution manifold for heating circuits
• Application: underfloor heating and multi-zone radiator systems

How to use

Mount the manifold securely on a suitable wall or within a service cabinet, ensuring correct orientation of the supply and return sides. Connect the 1" supply line from the heat source to the supply header and connect each circuit to the corresponding 1/2" return outlet using compatible fittings. After mechanical connections are completed, flush and fill the system according to standard hydronic installation procedures, then set and balance flows for each circuit as required. Ensure access for future adjustments and maintenance.

Usage recommendations

Use compatible fittings and follow local plumbing codes; perform system flushing before commissioning and verify hydraulic balance after installation. For optimal performance, pair the manifold with appropriate flow meters or balancing valves on each circuit where precise control is required.
