Stainless Steel Underfloor Heating Manifolds
Our range of stainless steel underfloor heating manifolds provides reliable and efficient heat distribution for modern underfloor heating systems. Designed to manage multiple heating circuits from a single central point, these manifolds allow precise control of water flow through each heating loop, ensuring consistent warmth across every room.
Manufactured from high-quality corrosion-resistant stainless steel, our manifolds are built for durability and long-term performance. Each manifold is compatible with standard 16mm underfloor heating pipe and features integrated flow meters for accurate circuit balancing, allowing installers to easily adjust the flow rate through each loop.
Our manifolds are available in a variety of circuit sizes to suit both single room installations and larger multi-zone heating systems.

Types of Underfloor Heating Manifolds
To suit different installer preferences and system requirements, we offer three styles of stainless steel underfloor heating manifolds: Standard, Poly Style, and Auto Balancing. All three designs perform the same core function — distributing heated water evenly throughout the underfloor heating system — but they offer slightly different features depending on installation preference.
Underfloor Heating Manifold Comparison
| Manifold Type | Key Feature | Best For |
|---|---|---|
| Standard Manifold | Traditional manual flow balancing using integrated flow meters | Installers who prefer a simple, proven UFH manifold design |
| Poly Style Manifold | Integrated fill and drain valves built directly into the manifold | Installations where easier filling and flushing is preferred |
| Auto Balancing Manifold | Automatic circuit flow regulation | Larger systems where automatic balancing can simplify setup |
Standard Stainless Steel Manifolds
The standard stainless steel underfloor heating manifold is the most widely used option in UFH installations. It features integrated flow meters that allow installers to manually adjust and balance each heating loop.
- Simple and reliable design
- Easy manual balancing using flow meters
- Widely used by installers across the UK
- Ideal for most domestic underfloor heating systems
Poly Style Underfloor Heating Manifolds
The poly style manifold features integrated fill and drain valves, allowing the system to be filled, flushed and serviced without needing additional fittings.
- Integrated filling and draining valves
- Reduces the need for extra installation components
- Simplifies system commissioning
- Clean, compact manifold layout
Auto Balancing Underfloor Heating Manifolds
Auto balancing manifolds regulate flow automatically across heating circuits, helping maintain consistent system performance with minimal manual adjustment.
- Automatic flow regulation
- Reduces time spent balancing circuits
- Ideal for multi-zone systems
- Helps maintain consistent heat distribution
Compatible Underfloor Heating Components
Our stainless steel manifolds are designed to integrate seamlessly with other underfloor heating system components, including:
Choosing the Right Underfloor Heating Manifold
In practice, the choice between standard, poly style, and auto balancing manifolds often comes down to installer preference and installation style rather than performance differences.
All of our stainless steel underfloor heating manifolds provide:
- Reliable water distribution
- Precise flow control
- Compatibility with modern UFH systems
- Long-lasting corrosion-resistant construction
Underfloor Heating Manifold FAQs
Below are some of the most common questions about stainless steel manifolds, including how they work, how many circuits they can control, and whether they require balancing during installation.
Q1: What does an underfloor heating manifold do?
An underfloor heating manifold acts as the central control point of a water underfloor heating system. Its main job is to distribute heated water from the heat source evenly across multiple heating circuits installed beneath the floor.
The manifold connects to each loop of underfloor heating pipe, allowing the system to supply warm water to each room or zone independently. Integrated flow meters and isolation valves allow installers to control how much water flows through each circuit, helping ensure consistent heat distribution throughout the property.
Most manifolds also connect to system components such as manifold pump and mixing valve sets, wiring centres, and thermal actuators, allowing thermostats to automatically control heating zones throughout the home.
In simple terms, the manifold ensures that heated water is distributed evenly, controlled accurately, and balanced correctly across every underfloor heating circuit.
Q2: How many circuits can a UFH manifold control?
A typical UFH manifold can control anywhere from 2 to 12 heating circuits, depending on the size of the manifold. Each circuit connects to a loop of underfloor heating pipe installed beneath the floor, usually covering a specific room or heating zone.
For example:
- 2–4 port manifolds are commonly used for small systems such as bathrooms, kitchens, or single-room installations.
- 5–8 port manifolds are ideal for medium-sized homes or multi-room heating systems.
- 9–12 port manifolds are typically used in larger properties where multiple zones of underfloor heating are required.
If more circuits are needed, installers can install multiple manifolds connected to the same heating system. Each circuit can also be individually controlled using thermostats, wiring centres, and thermal actuators to create a fully zoned heating system.
Q3: Do underfloor heating manifolds need balancing?
Yes, most underfloor heating manifolds need to be balanced during installation to ensure that each heating circuit receives the correct flow of warm water.
Balancing is achieved by adjusting the flow meters on the manifold, which regulate the flow rate through each loop of underfloor heating pipe. Because different pipe circuits can vary in length, balancing ensures that longer loops receive enough flow while shorter loops are not over-supplied.
Correct balancing helps ensure:
- Even heat distribution across all rooms
- Efficient system performance
- Reduced energy consumption
- Improved comfort throughout the property
Some modern auto-balancing manifolds can automatically regulate flow between circuits, reducing the need for manual adjustment during system commissioning.
