Controlled manifold with flowmeter 4-way U-TUBE for underfloor heating, model 18852004C

The U-TUBE controlled manifold with flowmeter 4-way (model 18852004C) is a hydraulic manifold developed for underfloor heating systems. It combines four independently metered outlets with control capability to distribute heated water across multiple floor heating loops. The unit is intended for balancing and monitoring flow rates during installation and routine maintenance, providing a compact solution for multi-loop hydronic distribution.

Advantages

This controlled manifold integrates individual flowmeters for each of the four circuits, enabling accurate flow measurement and adjustment without separate external meters. The compact 4-way arrangement simplifies pipe routing and reduces installation space compared with multiple single manifolds. Durable materials and a design intended for hydronic systems help ensure reliable performance and straightforward maintenance access.

Suitable for

• Residential and small commercial underfloor heating installations with up to four circuits
• Retrofit projects where balanced flow and easy monitoring are required
• New builds requiring centralized distribution and per-circuit flow adjustment
• Maintenance tasks that need individual circuit flow verification and balancing

When it may not be suitable

This 4-way manifold is not suitable for systems that require more than four independent heating circuits; larger installations will need manifolds with additional outlets or multiple units. It is designed for hydronic underfloor heating applications and may not be appropriate for non-heating fluid types or systems with incompatible connection sizes or materials.

Key specifications

• Number of outlets: 4 independently metered circuits
• Integrated flowmeters: individual measurement on each outlet for precise balancing
• Function: hydraulic distribution and flow control for underfloor heating loops
• Form factor: compact 4-way manifold assembly suitable for central distribution

How to use

Install the manifold in the heating distribution cabinet or manifold box following the piping layout for the underfloor heating system. Connect supply and return piping according to the system design, and attach each floor heating circuit to its respective outlet. During commissioning, use the integrated flowmeters to set and balance the desired flow rates for each loop, adjusting valves as required. Regularly inspect the flowmeters and valves for proper operation and perform adjustments during maintenance or after system changes.

What to consider before purchase

• Compatibility with the system’s pipe sizes, connection types, and working fluid
• Number of heating circuits required now and potential future expansion needs
• Available installation space and whether a compact 4-way manifold fits the manifold box or cabinet
• Required accessories such as actuators, mounting brackets, or isolation valves that may be sold separately

Usage recommendations

For accurate balancing, commission each circuit at the expected operating temperature and flow conditions. Use the integrated flowmeters to record baseline flow rates and re-check after the system reaches steady state. If actuators are added, verify compatibility and ensure control wiring and power are installed according to the actuator manufacturer’s instructions.
