Manifolds

Polypipe offers a broad range of manifold and water temperature controls for both traditional and underfloor heating applications.

Manifolds are used in all underfloor heating systems above 30m2, irrespective of floor type. Manifolds are supplied complete and fixed with a wall mounting bracket. The manifold comes complete with a drain and air vent assembly, which can be positioned on either end of the manifold, and isolation valves are supplied separately for the supply end of the manifold.

We offer a range of 15mm push-fit manifolds for use with 12mm and 15mm pipe systems and compression manifolds for use with our 16mm and 18mm pipe systems.

Each Polypipe manifold includes a flow meter on each flow port to provide a visual indicator of the flow-through rate of each circuit.

Manifolds installation guidance
  • Step 1: Assembly and installation

    Assemble all components (1 to 6) to the Isolation Valves (PB01732).

  • Step 2: Connect units and valves to manifolds

    Connect the assembled Unit and Isolation Valves to the Flow and Return Manifolds.

  • Step 3: Pipework connections

    Connect the heating Flow and Return Pipes as shown. These connections are 3/4” BSP Connections. Use Polyplumb PB4322 Male BSP adaptor (not included).

  • Step 4: Connect Zone Valve to Flow pipework

    Connect the 22mm Zone Valve to the Flow pipework.

  • Step 5: Commissioning

    Ensure that the pipework and Pump are fully vented.

  • Step 6: Set the speed

    Set the Pump at speed. Speed Two is recommended for initial setting.

  • Step 7: Set the temperature

    If serving a solid floor, set the temperature on the mixing valve to minimum and increase by 5°C per day until the desired temperature is reached. For other floor systems set the temperature of the mixing valve to the design temperature.
