U-TUBE Controlled Manifold with Flowmeter, 7-Port

The U-TUBE 7-port controlled manifold is a high-performance component engineered for modern underfloor heating systems. This manifold facilitates the precise distribution of heated water across seven individual heating circuits, ensuring that each zone receives the exact flow required for consistent thermal comfort. By integrating high-quality flowmeters directly into the manifold assembly, the system allows for real-time monitoring and manual adjustment of water circulation, which is essential for maintaining a balanced and efficient heating network in both residential and commercial buildings.

Advantages

The primary benefit of this manifold is its ability to provide granular control over the heating system, which directly contributes to improved energy efficiency and reduced operational costs. The integrated flowmeters simplify the balancing process, allowing installers to verify flow rates visually without the need for complex external tools. Constructed from durable materials, the manifold is designed to withstand the pressures and temperatures typical of hydronic heating environments, ensuring long-term reliability and minimal maintenance requirements. Its seven-port configuration provides sufficient capacity for medium-sized heating zones, making it a versatile choice for various floor layouts.

Suitable for

• Residential underfloor heating installations
• Commercial building climate control systems
• Multi-zone heating configurations
• Renovation projects requiring precise flow balancing

This manifold may not be suitable for systems requiring more than seven heating circuits unless multiple units are connected in parallel. It is also not intended for use with steam heating systems or high-pressure industrial applications that exceed the manufacturer's specified operating limits.

Key specifications

• Number of ports: 7
• Integrated flowmeters for each circuit
• Material: Corrosion-resistant alloy
• Compatibility: Standard hydronic underfloor heating pipes
• Function: Individual circuit flow regulation

To use the manifold, connect the supply and return lines from the heat source to the main manifold headers. Once the underfloor heating loops are connected to the individual ports, use the integrated flowmeters to adjust the flow rate for each circuit according to the specific heating requirements of the room. This balancing process ensures that all areas reach the desired temperature uniformly. Regular checks of the flowmeter indicators are recommended to ensure the system remains balanced over time.

What to consider before purchase

• Ensure the number of heating circuits matches your floor plan requirements
• Verify compatibility with your existing pipe diameter and connection type
• Confirm the manifold dimensions fit within your designated cabinet or wall space
• Check that the system pressure and temperature ratings align with your heat source

Usage recommendations

For optimal performance, it is recommended to perform a full system flush before installation to prevent debris from affecting the flowmeter accuracy. Always consult with a professional heating engineer to ensure the manifold is correctly sized and balanced for your specific heating load.
