Heating manifold Afriso ProCalida EF1 K for 7 heating circuits, connection G1, flow 0.2–1.6 l/min

Afriso ProCalida EF1 K heating manifold for 7 heating circuits with G1 connection and flow range 0.2–1.6 l/min is a compact distribution unit designed for multi-zone hydronic heating systems. It provides controlled distribution of heating medium to seven separate circuits, enabling independent flow balancing and efficient operation of underfloor or radiator heating zones. The unit is engineered for integration into residential and light-commercial installations where reliable flow control and straightforward plumbing connections are required.

Advantages

The manifold supports seven circuits with individual flow balancing, reducing uneven heat distribution and improving system efficiency. Its G1 connection simplifies installation with standard pipework fittings, and the defined flow range of 0.2–1.6 l/min per circuit allows accurate regulation for different zone demands. Constructed from corrosion-resistant materials and designed for hydraulic stability, the unit helps maintain consistent temperatures and reduces the need for frequent adjustments.

Suitable for

• Multi-zone underfloor heating systems in single-family homes
• Small to medium residential radiator circuits with separate zone control
• Light-commercial spaces requiring multiple heating zones
• Retrofit projects where balanced flow distribution is needed

Key specifications

• Number of heating circuits: 7
• Connection size: G1
• Flow range per circuit: 0.2–1.6 l/min
• Function: hydraulic distribution and flow balancing for multiple heating zones
• Compatible with water-based hydronic heating systems

How to use

Install the manifold on a stable mounting surface according to local plumbing codes and the system design. Connect the supply and return lines to the G1 inlet and outlet, and run individual circuit pipes from each port to the respective heating zones. Use the built-in flow adjustment features to set the required flow for each circuit within the 0.2–1.6 l/min range, ensuring balanced distribution. After installation, purge air from the system and check all connections for leaks before commissioning.

Usage recommendations

For optimal performance, commission the manifold together with a system-level balancing and temperature control routine. Verify that pump selection and differential pressure settings match the manifold’s flow characteristics, and schedule periodic inspections to check for sediment or air accumulation. Use compatible valves and fittings and follow applicable installation standards to ensure long-term reliability.
