12mm x 1.5mm PE-RT Underfloor Heating Pipe with EVOH Oxygen Barrier

Experience reliable, high-efficiency heating with the eZheat 12mm x 1.5mm PE-RT Oxygen Barrier Pipe. Designed for underfloor heating systems, this flexible and durable pipe ensures even heat distribution, long-term stability, and complete protection against corrosion.

Key Features

High-Performance PE-RT Construction: Made from Polyethylene of Raised Temperature Resistance (PE-RT) for outstanding flexibility, durability, and heat resistance. Ideal for easy installation and long service life.

Integrated EVOH Oxygen Barrier: The EVOH (Ethylene Vinyl Alcohol) layer prevents oxygen from diffusing into the system water, protecting metal components such as manifolds, pumps, and boilers from corrosion and sludge buildup.

Exceptional Thermal Stability: Withstands continuous operation at 110°C and pressure of 1.9MPa for up to 8,760 hours — ensuring no leaks or breaks.

Dimensional Accuracy: Longitudinal reversion rate ≤ 2%, maintaining pipe integrity and performance under thermal stress.

Proven Pressure Resistance: Rigorously tested under hydrostatic pressure conditions:
• 9.9 MPa @ 20°C / 1 hour
• 3.8 MPa @ 95°C / 22 hours
• 3.6 MPa @ 95°C / 165 hours
• 3.4 MPa @ 95°C / 1,000 hours
