Material & Specifications

Key Advantages

• Exceptional Flexibility – PE-RT offers superior flexibility compared to PEX, enabling tight bending radii and easier installation. Can be installed in continuous lengths without excessive fittings, reducing potential leak points.

• High Temperature Resistance – Designed for continuous operation up to 70°C, with transient tolerance up to 90°C. Maintains mechanical properties under sustained thermal stress.

• Full Oxygen Barrier – Integrated EVOH (ethylene vinyl alcohol) oxygen diffusion barrier prevents oxygen ingress into the system, protecting metal components (boilers, pumps, manifolds) from corrosion and extending system lifespan.

• Chemical & Corrosion Resistance – Inert material resistant to common chemicals, scale buildup, and electrochemical corrosion. Compatible with standard antifreeze solutions used in heating systems.

• Smooth Internal Surface – Low friction coefficient ensures optimal flow rates and minimizes pressure loss, improving system efficiency.

• Memory-Free Properties – Unlike PEX, PE-RT does not require cross-linking during manufacturing. The pipe can be easily uncoiled, laid flat, and retains its shape after bending without spring-back, simplifying installation.

• Long Service Life – Designed for service life exceeding 50 years under normal operating conditions, backed by extensive international field performance data.

Applications

• Residential underfloor heating systems

• Commercial building radiant heating

• Hydronic heating systems (floor, wall, ceiling)

• Snow melting systems for driveways and walkways

• Heat pump and solar thermal heating systems

• Low-temperature heating applications

• Radiator connections and distribution systems

System Components

The complete PE-RT underfloor heating system includes:

• Coiled pipes in various diameters and lengths

• Manifolds and distribution units

• Fittings (press, compression, or fusion types)

• Insulation panels and installation accessories

• Fixing clips, rails, and staples

Connection Methods

Installation Overview

The pipe is supplied in coils for continuous installation. Installation methods include:

• Wet System: Embedded in concrete screed for maximum thermal mass

• Dry System: Installed under subfloor or in grooved panels for lightweight construction

• Staple-Up: Secured beneath wood-framed floors

The pipe's flexibility allows for easy layout in serpentine or spiral patterns with minimal fittings.

Standards & Compliance

Our PE-RT Underfloor Heating Pipe is manufactured in compliance with:

• ISO 22391 (international standard for PE-RT piping systems)

• DIN 4729 / DIN 4726 (German standards for underfloor heating)

• ASTM F2769 (US standard)

• EN 1264 (European standard for floor heating systems)

Quality Assurance

All products undergo rigorous quality control, including dimensional verification, pressure testing, oxygen barrier integrity testing, and visual inspection, ensuring consistent quality and reliable performance.
