Underfloor heating controlled manifold with flowmeter, U-TUBE CONTROLLED MANIFOLD WITH A FLOWMETER 6

The U-TUBE controlled manifold with flowmeter 6 is a hydraulic distribution unit designed for underfloor heating systems with up to six circuits. It combines distribution, individual circuit flow measurement and manual adjustment in a single compact assembly. The integrated flowmeters allow visual monitoring of each loop's flow rate, while ball valves and regulation knobs enable balancing and isolation of individual circuits. The manifold is intended for residential and light commercial underfloor heating installations where accurate flow control and straightforward visual indication are required.

Advantages

The manifold provides precise hydraulic balancing through individual flow adjustment for each of the six circuits, improving system efficiency and temperature uniformity. Integrated transparent flowmeters give clear visual feedback for commissioning and routine checks without additional measurement tools. The compact assembly reduces installation time and space compared with separate components, and the unit is compatible with standard underfloor heating piping and fittings when installed according to system requirements.

Suitable for

• Residential underfloor heating with up to six circuits
• Light commercial underfloor heating zones
• Systems requiring visual flow indication and manual circuit balancing
• Retrofit projects where a compact distribution manifold is needed

Key specifications

• Number of circuits: up to six independently adjustable loops
• Integrated flowmeters: one per circuit for visual flow monitoring
• Control elements: manual regulation knobs and isolation valves for each loop
• Material and finish: corrosion-resistant metals and transparent flowmeter housings for durability and visibility
• Connection compatibility: designed for standard underfloor heating piping dimensions and fittings
• Mounting: wall or frame mounting options to fit manifold cabinets or installation panels

How to use

Install the manifold in the designated manifold cabinet or on a suitable mounting frame, following local plumbing and heating regulations. Connect supply and return lines to the respective headers and attach each circuit pipe to its dedicated port. During commissioning, use the integrated flowmeters and regulation knobs to set and balance the flow for each circuit according to calculated design flow rates or temperature requirements. Isolate individual loops using the built-in valves when servicing or testing circuits. Perform visual checks of the flowmeters periodically to ensure balanced operation and to detect any deviations that may indicate air or blockage in circuits.

Usage recommendations

For reliable long-term performance, flush the heating circuits before manifold installation, secure all connections per manufacturer torque recommendations, and use appropriate air separation and filtration devices upstream of the manifold. When adjusting flows, follow hydraulic design values and recheck temperatures after any balance changes.
