Manifold for heating systems Immergas ROZDZIELACZ DIM 2 ZONE ERP, 2-zone hydraulic distributor

The Immergas ROZDZIELACZ DIM 2 ZONE ERP hydraulic manifold is designed to distribute and balance hot water between two independent heating circuits. It allows separation of two zones for individual control, simplifying the linkage between a central boiler, zone valves or actuators, and the connected radiators or underfloor heating loops. The unit supports flow adjustment and isolation to streamline commissioning and maintenance of small residential or light commercial heating systems.

Advantages

This 2-zone hydraulic distributor provides reliable hydraulic separation and balanced flow to each circuit, reducing temperature differences and ensuring stable heat delivery. The compact assembly simplifies installation in tight plant rooms and reduces the need for multiple fittings. Built for compatibility with common boilers and actuator types, it enables clearer system layout and easier troubleshooting during operation.

Suitable for

• Residential central heating systems with two independently controlled zones
• Small commercial installations requiring zoned temperature control
• Combined radiator and underfloor heating systems where separate flow regulation is needed
• Replacement or upgrade of existing two-zone manifold assemblies

Key specifications

• Number of zones: 2 independent hydraulic circuits
• Function: distribution and balancing of hot water for heating
• Flow control: individual circuit flow adjustment and balancing
• Isolation: valves for circuit shut-off during maintenance
• Compatibility: designed for connection to standard boilers, actuators and piping used in residential and small commercial systems
• Installation: compact manifold layout for wall-mounting or cabinet installation

How to use

Install the manifold in the heating plant room according to local regulations and manufacturer installation practices, ensuring correct orientation and secure mounting. Connect the supply and return from the boiler to the manifold inlet and outlet, then connect each zone piping to its respective circuit ports. Fit actuators or zone valves to the designated outlets if automatic control is required, and use the balancing valves to set the desired flow rate for each zone. After filling and venting the system, check for leaks and verify that each zone receives the required flow and temperature during commissioning.

Usage recommendations

For reliable operation, use appropriately sized actuators and ensure system filters and air vents are in place. Perform balancing adjustments during stable operating conditions and re-check after initial heating cycles. Follow local plumbing codes and consult a qualified heating engineer for system design and commissioning.
