Stainless Steel Underfloor Heating Manifolds

NovaTherm Stainless Steel Underfloor Heating Manifolds – 2 to 12 Port

Choosing the right underfloor heating manifold is essential for reliable water distribution, accurate flow balancing and efficient operation in a wet underfloor heating system.

At Underfloor Heating Trade Supplies, we supply premium NovaTherm Stainless Steel Underfloor Heating Manifolds, available in configurations from 2 to 12 ports, together with a comprehensive range of compatible manifold fittings, controls and installation accessories.

Our pre-assembled manifolds are designed for use in water underfloor heating systems and suitable wall-mounted radiator heating applications, providing professional installers with a practical solution for distributing heated water between individual circuits.

Whether you're installing underfloor heating in a new-build home, an extension, a renovation project or a larger commercial property, our manifold range offers flexibility, quality and value.

What Is an Underfloor Heating Manifold?

An underfloor heating manifold is the central distribution point of a water-based underfloor heating installation.

It distributes heated water from the heating source into individual underfloor heating pipe circuits and collects the returning water, allowing the flow through each circuit to be balanced according to the system design.

By regulating water flow to individual circuits, installers can help ensure that each heated area receives the appropriate level of heat.

When combined with compatible thermostats, manifold actuators and wiring controls, the manifold can also support independent temperature control across multiple rooms or heating zones.

Key Features & Benefits of NovaTherm Stainless Steel Manifolds

Our NovaTherm manifolds are supplied pre-assembled with a range of practical features designed to simplify installation, commissioning and ongoing maintenance.

Premium Stainless Steel Construction

Manufactured from durable stainless steel, the manifold assembly is designed to provide reliable performance in appropriately installed water-based heating systems.

Adjustable 0–5 Litres/Minute Flow Meters

Each manifold features adjustable flow meters with indicators covering 0–5 litres per minute, allowing installers to observe and regulate the water flow through individual heating circuits.

This enables accurate balancing of the system according to the flow rates specified in the underfloor heating design.

10-Bar Pressure Gauge

An integrated pressure gauge provides a convenient visual indication of system pressure during filling, testing and operation.

Automatic Air Vent

The built-in automatic air vent helps remove accumulated air from the manifold assembly, supporting effective filling and reliable heating system operation.

Integrated Filling & Draining Valves

The manifold features filling and drain-off points, making it easier to fill, flush and drain individual circuits during installation, commissioning or maintenance.

Manual & Automatic Circuit Control

The return manifold incorporates adjustable valve pins that can be operated using the supplied manual adjustment caps.

For automatic multi-zone control, compatible electronic manifold actuators can be fitted and connected to appropriate thermostats and wiring controls.

Convenient Wall-Mounted Installation

Each manifold is supplied with mounting brackets, allowing the assembly to be securely positioned on a suitable wall or within an appropriately sized manifold cabinet.

Standard Connection Dimensions

The manifold features a standard 210mm spacing between the flow and return bars, together with 50mm centre-to-centre spacing between individual ports.

This arrangement provides a practical layout for pipe connections and compatibility with suitable pump and mixing units.

Available Underfloor Heating Manifold Sizes

We stock NovaTherm stainless steel manifolds in configurations from 2 to 12 ports.

These dimensions are taken from the NovaTherm manufacturer's datasheet and help installers plan the space required for manifold positioning.

When selecting a manifold, remember that the number of ports refers to the number of heating circuits rather than necessarily the number of rooms.

A larger room may require multiple pipe circuits, while several smaller rooms may each require an individual circuit.

The correct manifold size should always be determined by the underfloor heating design.

Compatible Underfloor Heating Pipe & Connections

NovaTherm stainless steel manifolds are designed to accommodate a range of appropriately matched multilayer pipe sizes.

The manufacturer recommends using pipe no larger than 20mm diameter with NovaTherm manifold connector fittings.

The manifolds also feature 1-inch threaded inlets for suitable isolation valves and associated heating components.

For reliable connections, always select compatible manifold connector cores and fittings that match the pipe's external diameter and wall thickness.

Our range of NovaTherm multilayer pipe includes:

• 12mm PERT-AL-PERT Pipe – For compatible compact and low-profile underfloor heating installations.

• 16mm PERT-AL-PERT Pipe – A popular option for wet underfloor heating circuits.

• 16mm and 20mm PEX-AL-PEX Pipe – For compatible heating and distribution applications.

Correct pipe and connector compatibility must always be confirmed before installation.

Multi-Zone Underfloor Heating & Room Temperature Control

NovaTherm stainless steel manifolds can form part of a multi-zone underfloor heating system, allowing different areas of a property to be controlled independently when appropriate equipment is installed.

The manifold's return valves can be operated manually using the supplied adjustment caps or fitted with compatible electrothermal actuators for automatic control.

When connected to suitable thermostats and a wiring centre, actuators open and close individual heating circuits according to the requirements of each heating zone.

This arrangement can provide:

• Independent temperature control in different rooms

• Flexible heating schedules

• Improved room-by-room comfort

• More efficient management of heating demand

• Control over individual circuits or groups of circuits

Please note: Thermostats, wiring centres and electronic manifold actuators are separate components and should be selected according to the requirements of the installation.

Suitable for Heat Pump & Boiler-Fed Heating Systems

Our NovaTherm manifolds are suitable for integration into appropriately designed water underfloor heating systems supplied by compatible heat sources, including:

• Air-source heat pumps

• Ground-source heat pumps

• Gas boilers

• Other suitable water-based heating systems

Underfloor heating manifolds play an important role in distributing water evenly between heating circuits.

The manufacturer specifies a standard 210mm distance between the flow and return bars, making the manifold suitable for use with various compatible mixing units.

The correct pump, mixing arrangement, flow temperatures and controls must be selected according to the heat source and system design.

Straightforward Filling, Balancing & Commissioning

NovaTherm manifolds are designed with features that help professional installers carry out essential installation and commissioning tasks.

The integrated filling and draining points allow individual pipe circuits to be filled and flushed, helping remove trapped air before the heating system is commissioned.

The adjustable flow meters can then be used to balance the circuits according to their calculated requirements.

The manufacturer specifies a system pressure-test procedure in accordance with EN 1264-4:2009, with the installation tested between 4 and 6 bar.

All filling, pressure testing and commissioning should be completed by a competent installer in accordance with the manufacturer's instructions and the applicable system requirements.
