KLETT PE-RT EVOH Heating Pipe 14x2mm / 16x2mm for Underfloor Heating

The PE-RT EVOH hook-and-loop pipe is ideal for low-temperature heating systems with heat pumps, gas and pellet boilers, and solar systems. The maximum continuous operating temperature of 70 °C covers all modern low-temperature systems and is also suitable for standard gas boiler applications if correctly designed.

PE-RT (Polyethylene of Raised Temperature Resistance) is manufactured without a complex cross-linking process and offers high flexibility and easy processing. It is ideal for low-temperature systems (up to 70 °C continuous operation). PE-Xa achieves higher temperatures (95 °C) and is suitable for more demanding applications.

Yes, the EVOH oxygen diffusion barrier in the PE-RT EVOH hook-and-loop pipe reliably prevents oxygen from entering the heating water. This effectively prevents corrosion of the boiler, circulation pump, heating circuit manifold, and system components made of steel or cast iron.

The pipe is pressed directly onto the MC Klett fleece (Slim, Silent, or TempusFlat) and adheres securely without clips. The minimum bending radius of ≥ 5 × outer diameter allows for tight curves and flexible laying patterns. The printed 50 mm grid enables precise pipe spacing from 50–300 mm.

The PE-RT EVOH hook-and-loop pipe is available as rolled goods in 200 m and 500 m rolls. To calculate the exact requirements, we recommend our free configurator, which calculates the heating area, pipe length, and budget for your project in under 90 seconds.
