Water Underfloor Heating Pipe – WRAS-Approved NovaTherm Multilayer Pipe
Choosing the right underfloor heating pipe is essential for achieving a reliable, efficient and long-lasting wet underfloor heating installation.
At Underfloor Heating Trade Supplies, we supply a comprehensive range of high-quality NovaTherm multilayer composite pipes, suitable for water underfloor heating, central heating distribution and compatible plumbing applications.
Our NovaTherm pipe range is WRAS approved and backed by a 50-year manufacturer's warranty, subject to the applicable manufacturer's terms and conditions.
Whether you're installing underfloor heating in a single room, renovating an entire property or working on a large commercial heating project, we have pipe options to suit your requirements.
PERT-AL-PERT Pipe – Designed for Water Underfloor Heating
Our NovaTherm PERT-AL-PERT underfloor heating pipe is specifically suited to modern water-based underfloor heating systems.
PERT-AL-PERT stands for Polyethylene of Raised Temperature Resistance – Aluminium – Polyethylene of Raised Temperature Resistance.
This multilayer construction combines flexible PE-RT plastic layers with a central aluminium core, offering excellent dimensional stability, an effective oxygen barrier and reliable performance in correctly designed heating systems.
The flexible construction makes PERT-AL-PERT an excellent choice for continuous underfloor heating circuits, helping installers create efficient pipe layouts while minimising unnecessary joints within the heated floor.
Our range includes:
12mm PERT-AL-PERT Underfloor Heating Pipe
Available in 80m and 240m coils, our 12mm pipe is particularly suitable for compatible low-profile underfloor heating systems and applications where smaller-diameter pipework is required.
Its compact diameter makes it useful for appropriately designed renovation and retrofit projects.
16mm PERT-AL-PERT Underfloor Heating Pipe
Available in 80m, 100m, 150m, 200m, 300m and 500m coils, our 16mm pipe is a popular choice for traditional wet underfloor heating installations.
Suitable for correctly designed screeded and compatible low-profile systems, it offers an excellent combination of flexibility, durability and ease of installation.
Both sizes are suitable for use in appropriately designed systems, with pipe spacing, maximum circuit lengths and operating temperatures determined by the manufacturer's specifications and system design.
PEX-AL-PEX Pipe – Plumbing & Heating Distribution
Alongside our specialist underfloor heating pipe, we also supply NovaTherm PEX-AL-PEX multilayer composite pipe.
PEX-AL-PEX is manufactured using cross-linked polyethylene layers surrounding a central aluminium core, combining the practical benefits of flexible plastic pipework with the dimensional stability of aluminium.
This construction makes it particularly suitable for compatible plumbing, central heating and heating distribution applications.
Our PEX-AL-PEX range includes:
| Pipe Diameter | Coil Length |
|---|---|
| 16mm | 100 metres |
| 20mm | 50 metres |
| 25mm | 50 metres |
| 32mm | 50 metres |
PEX-AL-PEX pipe is a practical choice for connecting heating system components, radiator circuits and compatible heating distribution networks.
It can also be used in appropriately designed heat pump heating installations, where the correct pipe diameter and flow rates are especially important.

WRAS-Approved Pipe for Added Confidence
Product quality and compliance are important considerations when selecting heating and plumbing components.
Our NovaTherm multilayer pipe range benefits from WRAS approval, providing assurance that the products meet the relevant requirements covered by their approval.
When selecting pipework, fittings and associated components, always ensure that the specific products are compatible with the intended installation and meet applicable water supply and heating system requirements.
NovaTherm 50-Year Manufacturer's Warranty
Our NovaTherm multilayer pipe range is backed by a 50-year manufacturer's warranty, demonstrating the manufacturer's commitment to product quality.
The warranty provides protection against qualifying defects in materials or manufacture under normal conditions of use.
Correct system design, installation and operation are essential. The warranty is subject to the manufacturer's applicable terms, conditions and exclusions.
Underfloor Heating Pipe for Heat Pump Systems
Modern air-source and ground-source heat pumps are often used alongside water underfloor heating because both can operate effectively as part of appropriately designed low-temperature heating systems.
Underfloor heating distributes warmth across a large floor area, potentially allowing the system to operate at lower water temperatures than conventional radiators.
Our PERT-AL-PERT underfloor heating pipe is well suited to the heating circuits in compatible heat pump-powered underfloor heating systems.
Our larger-diameter PEX-AL-PEX multilayer pipe can also provide suitable options for heating distribution pipework, subject to system design, flow requirements and operating conditions.
