FAQs

What pipe sizes is this manifold compatible with?

This specific 8 Port manifold is available in variants compatible with 12mm, 15mm, 17mm, and 20mm pipe diameters, all utilizing standard euro cone fittings.

Can I install this myself?

Installation requires basic plumbing knowledge and standard plumbing tools. If you are not comfortable with plumbing work, it is recommended to hire a qualified professional.

What is the purpose of the automatic air vent?

The automatic air vent continuously releases any trapped air from the manifold and connected pipework, which improves heating efficiency and prevents issues like noise or poor circulation.

How do I drain the system using the manifold?

Connect a hose to the filling/drain off valve and open the valve slowly to allow the system water to drain out. Ensure the system is isolated from the main water supply before draining.

Does the manifold come with a mounting bracket?

Yes, the manifold comes pre-mounted on an installation bracket, which can be assembled for left or right-hand installation.

What is the material of the manifold?

The manifold is constructed from durable brass for reliable performance and longevity.

How do I check the system pressure?

The manifold is equipped with a pressure gauge end unit. You can read the system pressure directly from this gauge.

Troubleshooting

Manifold not distributing heat evenly to all loops.

Check for trapped air in the loops or manifold; use the automatic air vent. Ensure the pressure is correct. Verify that flow rates to each loop are balanced, potentially by adjusting individual loop valves if present or by checking for blockages.

Leaking connections at the manifold ports.

Ensure all euro cone fittings are correctly installed and tightened. Check that pipe ends are clean and square. For persistent leaks, re-seat the fitting or consider replacing the seal/olive if applicable.

Low system pressure reading.

Check the main heating system for leaks. Use the filling/drain off valve to top up the system pressure to the manufacturer's recommended level for your boiler.

Automatic air vent not releasing air.

Ensure the air vent cap is not overtightened or blocked. In some cases, manual bleeding might be required initially if the system is heavily air-bound.

Pros and Cons

Pros

  • Enables precise control over multiple heating zones.
  • Durable brass construction ensures longevity.
  • Includes essential components like air vents and pressure gauges for system health.
  • Flexible installation options with reversible bracket.
  • Easy integration with various underfloor heating pipe types.

Cons

  • Requires basic plumbing knowledge for installation.
  • Not a standalone heating solution; requires a compatible boiler and heating system.
  • Eight ports might be excessive for very small or single-zone applications.

Setup, Compatibility & Care

Setup:

  1. Mount the pre-assembled bracket securely to a suitable surface.
  2. Attach the manifold to the bracket, configuring for left or right-hand supply as needed.
  3. Connect the main system supply and return pipes to the manifold inlet and outlet ports using appropriate fittings.
  4. Connect each underfloor heating loop to the individual ports on the manifold using the euro cone fittings compatible with your pipe size (e.g., 12mm, 15mm, 17mm, or 20mm).
  5. Ensure all connections are tight and leak-free.
  6. Follow the system filling and bleeding procedure, utilizing the filling/drain off valve and automatic air vent.

Compatibility:

  • Compatible with standard plumbing tools for installation.
  • Works with all standard euro cone fittings for pipe connections.
  • Suitable for use with any compliant boiler system or heat source suitable for underfloor heating.
  • Available in variants for 12mm, 15mm, 17mm, and 20mm pipe diameters.

Care:

  • Regularly check the pressure gauge to ensure it is within the recommended operating range.
  • Periodically inspect for any signs of leaks.
  • The automatic air vent typically requires no user maintenance, but ensure it is not obstructed.
  • The drain-off valve can be used for system flushing if required, following manufacturer guidelines for the overall heating system.
