Underfloor heating controlled manifold with flowmeter 9 zones U-TUBE

The U-TUBE controlled manifold with flowmeter for 9 zones is a compact hydraulic assembly designed for underfloor heating installations where individual circuit control and flow measurement are required. This manifold integrates a flowmeter for each circuit to enable monitoring and balancing of flow rates across nine heating loops. It is intended for use in residential and commercial underfloor heating systems to support even temperature distribution and precise hydraulic balancing.

Advantages

The manifold provides individual flow measurement and regulation for nine circuits, which helps ensure uniform heat delivery and reduces the risk of imbalanced temperatures between rooms. Integrated flowmeters simplify commissioning and routine adjustment by showing real-time flow for each zone. The modular design supports direct connection to actuators and thermostatic controls, allowing independent control of each loop. Built from materials suitable for heating system medium, the assembly is engineered to facilitate professional installation and accurate hydraulic balancing.

Suitable for

• Residential underfloor heating systems with up to nine circuits
• Commercial small-to-medium underfloor heating installations requiring per-zone flow control
• Renovation projects where existing manifolds are replaced with metered alternatives
• New builds where precise hydraulic balancing and easy commissioning are required

When it may not be suitable

This controlled manifold is intended for systems needing nine individually metered circuits; it may not be appropriate for installations with a different number of circuits unless manifold count and layout match the project design. It is not a complete heating control package on its own and requires compatible actuators, thermostats, and pump/boiler controls to provide full automation and temperature control.

Key specifications

• Number of zones: 9 independently metered circuits
• Integrated flowmeters: yes, one per circuit for flow monitoring and balancing
• Compatibility: designed for hot water underfloor heating systems
• Connections: standard hydraulic connections for supply and return manifolds (installation-specific fittings and sizes depend on installer configuration)
• Material characteristics: corrosion-resistant components suitable for potable heating medium environments
• Control interface: intended for use with standard thermal actuators and room thermostats (actuators not included)

How to use

Install the manifold in the plant room or distribution cabinet according to project hydraulic layout and local codes. Connect supply and return pipes, secure each circuit to its respective outlet and inlet, and mount compatible actuators and thermostats on the designated ports. During commissioning, use the integrated flowmeters to set and balance the flow for each zone to achieve the designer-specified flow rates. Verify system tightness, purge air from circuits, and test with the heating source running to confirm even temperature distribution across all zones.

What to consider before purchase

• Confirm the number of heating circuits required in the installation matches the nine-zone manifold
• Ensure compatibility with chosen actuators, thermostats, and hydraulic connection sizes
• Plan for professional installation and commissioning to achieve correct hydraulic balancing
• Verify available space in the plant room or distribution cabinet for manifold and actuator mounting

Usage recommendations

For reliable long-term performance, commission the system with measured flow values for each zone, use compatible actuators rated for underfloor heating service, and include routine checks of flowmeter readings and actuator function during seasonal maintenance.
