Heating manifold with coupling 3 circuits VIESSMANN 7773837

The VIESSMANN Heating manifold with coupling for three circuits is a compact hydraulic assembly designed to distribute and balance hot water flow between three independent heating circuits. Intended for use in multi-zone central heating systems, underfloor heating manifolds or radiator groups, the unit provides hydraulic separation and a coupling point for connection to the primary heating loop. The manifold allows straightforward integration into domestic or light-commercial heating installations where independent circuit control and even heat distribution are required.

Advantages

This 3-circuit manifold offers precise flow distribution across three separate circuits, improving temperature consistency and system efficiency. Integrated coupling simplifies hydraulic connection to the primary loop and reduces installation time. The compact design conserves space in plant rooms or service cupboards while maintaining access for valves and metering equipment. Materials and construction are selected to ensure reliable operation under typical residential heating conditions.

Suitable for

• Multi-zone central heating systems
• Underfloor heating installations with three circuits
• Groups of radiators requiring separate control
• Renovation projects where hydraulic separation is needed

Key specifications

• Number of heating circuits: 3
• Function: distribution and hydraulic coupling between primary and secondary circuits
• Application: domestic and light commercial heating systems, underfloor heating, radiator groups
• Design: compact manifold assembly with coupling for primary connection
• Control compatibility: suitable for integration with circuit valves, flow meters and balancing devices
• Installation orientation: fixed horizontal mounting in a heating plant or manifold cabinet

How to use

Install the manifold according to the system design and local regulations, positioning the coupling to connect to the boiler or primary loop. Connect each of the three secondary circuit outlets to their respective heating zones, and fit balancing valves, flow meters or actuators as required for control and commissioning. Flush and fill the heating system, vent air from the circuits, then perform hydraulic balancing and leak checks before commissioning. Follow manufacturer and local codes for pipe sizing, insulation and pressure testing.

Usage recommendations

For reliable operation, use appropriate balancing valves and flow measurement when commissioning three separate circuits. Regularly inspect joints and fittings for leaks and maintain system water quality to minimize corrosion and ensure long service life.
