Manifold (12-way) for heating systems FERRO RZP12S with thermostat valve and flow meters

FERRO RZP12S is a 12-way manifold engineered for hydronic heating systems, combining a thermostat valve on the supply side and individual flow meters on the return side. The unit enables balanced distribution of heated water to multiple circuits, offering measured flow control and visible flow readings for each zone. Its configuration supports both radiator and underfloor heating installations in residential and light commercial settings where stable temperature control and easy hydraulic balancing are required.

Advantages

The manifold integrates a single supply-side thermostat valve together with twelve return-side flow meters, allowing centralized regulation and individual circuit adjustment without additional fittings. Transparent flow indicators provide direct visual confirmation of circuit flow rates, helping to detect imbalances and simplify commissioning. The compact, modular design reduces pipework complexity and facilitates installation in standard manifolds cabinets or service rooms. Constructed from corrosion-resistant materials, the device is intended for long-term operation within typical hot-water heating system parameters.

Suitable for

• Residential multi-zone heating systems with radiators
• Underfloor heating installations requiring multiple controlled circuits
• Light commercial buildings with several independent heating zones
• Renovation projects where hydraulic balancing and monitoring are needed

Key specifications

• Number of circuits: 12
• Integrated components: supply-side thermostat valve; individual return flow meters
• Flow measurement: individual transparent flow indicators for each circuit
• Material characteristics: corrosion-resistant manifold body and fittings suitable for closed hot-water systems
• Mounting: wall- or cabinet-mountable manifold assembly for centralized distribution
• Compatibility: designed for hot-water hydronic heating with radiators and underfloor systems

How to use

Install the manifold according to the system layout, connecting the supply header to the heat source and routing each circuit from the supply to the intended heating loops or radiators. Use the integrated thermostat valve to set overall supply regulation and adjust individual flow meters on the return side to achieve desired flow rates per zone. Verify flow readings during commissioning and fine-tune each circuit to ensure even heat distribution. Follow applicable plumbing and heating codes and use appropriate sealing and mounting hardware.

Usage recommendations

During commissioning, adjust flow meters starting from the furthest circuit and move sequentially toward the manifold to achieve hydraulic balance. Periodically inspect flow indicators for proper operation and check connections for leaks. Use water treatment and filtration compatible with sealed heating systems to reduce risk of scaling and corrosion, and schedule routine maintenance to preserve metering accuracy and valve performance.
