FAQs
What size pipes does this manifold connect to?
This manifold is designed with 17mm pipe connections. You will need to use appropriate 17mm euro cone fittings to connect your underfloor heating pipes.
Is this manifold suitable for all UFH systems?
It is ideal for small to medium-sized UFH installations. For very large areas requiring more than 5 heating circuits, a manifold with more ports would be necessary.
What is the purpose of the pressure gauge?
The pressure gauge allows you to monitor the water pressure within your underfloor heating system. Consistent pressure is vital for efficient operation and safety.
How does the automatic air vent work?
The automatic air vent continuously releases trapped air from the system, preventing airlocks that can reduce heating efficiency and cause noise. It typically releases air when it builds up and the system is under pressure.
Can I install this myself?
The manifold is designed for straightforward installation and is suitable for both professional installers and DIY use. However, if you are not experienced with plumbing or UFH systems, professional installation is recommended.
What maintenance is required?
Regular checks of the pressure gauge and ensuring the air vent is clear are the primary maintenance tasks. Periodically inspect connections for leaks.
What does 'pre-mounted on an installation bracket' mean?
The manifold comes already attached to a mounting bracket, simplifying the process of securing it to your wall or installation board. You can then position the bracket and manifold as needed for your system.
Troubleshooting
Manifold is not heating the room evenly
Check if the automatic air vent is functioning and has released trapped air. Ensure all UFH loops are open and balanced using the control valves on the manifold.
Low pressure reading on the gauge
Check for leaks in the system. If no leaks are found, top up the system pressure via the filling/drain-off valve according to your boiler manufacturer's instructions.
Visible leaks from connections
Tighten the specific connection carefully. If the leak persists, the euro cone fitting or seal may need replacement.
Difficulty isolating a specific loop
Ensure the isolating valve for that loop is fully closed. If it is stiff, apply gentle pressure. For persistent issues, professional servicing may be required.
Pros and Cons
Pros
Durable and corrosion-resistant stainless steel construction.
Ensures balanced water flow for efficient heating.
Includes essential monitoring tools like a pressure gauge and air vent.
Supplied as a complete, pre-assembled unit for straightforward installation.
Flexible installation options with left/right hand supply capability.
Cons
Specific 17mm pipe connections may require euro cone adapters.
May not be suitable for very large UFH installations requiring more ports.
Requires manual tightening of euro cone fittings for pipe connections.
Pressure gauge requires periodic visual checks for system monitoring.
Setup, Compatibility & Care
Setup:
Mount the pre-assembled manifold onto the provided installation bracket, orienting it for left or right-hand supply as needed.
Connect the UFH pipes from each loop to the manifold ports using appropriate 17mm euro cone fittings. Ensure secure connections to prevent leaks.
Connect the primary flow and return pipes from the boiler or heat source to the 1-inch ball valves on the manifold.
Connect the filling and drain-off valve.
Purge the system of air using the automatic air vent and manual filling/drain-off valve.
Compatibility:
Designed for use with underfloor heating systems.
Features 17mm pipe connections. Use appropriate euro cone fittings for connecting 17mm UFH pipes. Adapters may be needed for other pipe sizes.
The 1-inch ball valves are standard connections for primary heating flow and return.
Care:
Periodically check the pressure gauge to ensure system pressure is within the recommended range.
Ensure the automatic air vent is functioning correctly; listen for any hissing sounds indicating air release.
Inspect connections for any signs of leaks or corrosion.
Clean the exterior of the manifold with a damp cloth. Avoid abrasive cleaners.
