Key Features of Our UFH Manifolds

Designed for Water Underfloor Heating UFH manifolds distribute warm water from the heat source to each underfloor heating pipe circuit.
Flow Control Flow meters help balance each loop, improving comfort and supporting even heat output across different rooms or zones.
Multiple Port Options Choose the manifold size to match the number of UFH circuits required for your project.
Pipe Connector Compatibility Connector cores are available for connecting common 12mm and 16mm underfloor heating pipe sizes to the manifold.
Zone Control Options Manifold actuators allow individual heating zones to open and close based on thermostat demand.
Trade & Domestic Use Suitable for installers, contractors and homeowners working on water underfloor heating systems.

Manifolds, Connector Cores and Actuators Explained

A water underfloor heating manifold is the central distribution point for the heating system. It sends warm water into each pipe loop and allows flow balancing across different rooms or zones. Connector cores are used to connect UFH pipe to the manifold, while actuators are fitted to manifold ports to provide automatic zone control from thermostats and wiring centres.

Component What It Does When You Need It
UFH Manifold Distributes heated water to each underfloor heating pipe circuit. For new water underfloor heating systems and manifold replacements.
Connector Cores Connect UFH pipe to the manifold using compression fittings. When fitting 12mm or 16mm pipe to manifold outlets.
Manifold Actuators Open and close manifold circuits to control individual heating zones. When using room thermostats and a wiring centre for zoned UFH control.
Blanking Caps Seal unused outlets or connections. When closing off an unused manifold or accessory connection.

Best Uses for Underfloor Heating Manifolds

New UFH Installations Use a manifold to distribute water through each underfloor heating loop in a new system.
Multi-Zone Heating Systems Combine manifolds with actuators and thermostats to control different rooms or zones independently.
Manifold Upgrades Replace older or damaged manifolds with a stainless steel UFH manifold assembly.
Pipe Connection & Maintenance Use connector cores, actuators and blanking caps when installing, servicing or adapting a manifold.

Frequently Asked Questions

What does an underfloor heating manifold do? An underfloor heating manifold distributes warm water to each UFH pipe loop. It also allows flow balancing, isolation and zone control when used with actuators and thermostats.
How many manifold ports do I need? The number of ports depends on the number of underfloor heating pipe loops in your system. Larger areas and multiple rooms usually require more loops and therefore more manifold ports.
What are manifold actuators used for? Manifold actuators open and close individual manifold circuits. They are typically controlled by room thermostats through a wiring centre to provide zoned underfloor heating control.
Do I need connector cores for underfloor heating pipe? Yes, connector cores are used to connect underfloor heating pipe to the manifold. Choose the correct size for your pipe, such as 12mm or 16mm.
Can I add actuators to a manifold later? In many systems, actuators can be added to compatible manifold ports later to create individual room or zone control. Always check compatibility with your manifold, thermostat and wiring centre.
