Product Overview

This PE-RT (Raised Temperature Polyethylene) pipe is designed for use in underfloor heating systems, offering excellent flexibility, durability, and long-term performance. Manufactured in accordance with DIN 16833, the pipe is suitable for modern low-temperature heating applications and provides reliable operation over its full service life.

The pipe incorporates an oxygen-impermeable barrier, compliant with DIN 4726, limiting oxygen diffusion to less than 0.1 g/m³ per day. This protects metal components within the heating system—such as manifolds, pumps, and valves—from corrosion.

Designed for application class 4, the pipe is ideal for area heating systems, delivering efficient heat transfer while maintaining system integrity under continuous operating conditions.

Frequently Asked Questions

  • What’s the difference between multi-layer and PEX underfloor heating pipe?

    PEX pipe is flexible and widely used for underfloor heating, while multi-layer pipe incorporates additional layers that can improve shape retention and reduce thermal expansion. The correct option depends on the system design and compatible fittings.

  • How much underfloor heating pipe do I need for my floor area?

    Pipe quantity depends on the heated floor area, pipe spacing, number of loops and maximum suitable loop length. A designed UFH layout provides a more accurate quantity than calculating from floor area alone.

  • What underfloor heating pipe spacing should I use?

    Pipe spacing should be determined by the room’s heat loss and required heat output rather than room type alone. Areas with higher heating demand may require closer pipe spacing.
