IFAN High Quality PEX-EVOH Pipes

Yes, they are the preferred choice

PEX-EVOH pipes are ideal for radiant floor heating. The oxygen barrier is specifically designed for these systems. They are the most widely used pipes for this application. Example: millions of square feet of floors use them worldwide.

Oxygen barrier protects the system

Radiant floors often have metal pumps and manifolds. Oxygen causes corrosion of these ferrous components. The EVOH layer blocks oxygen from entering the water. PEX-EVOH pipes protect the entire system from corrosion damage.

Temperature compatibility

Radiant floors operate at 35-45°C (95-113°F). This is well below the 95°C (203°F) PEX limit. PEX-EVOH pipes have ample temperature margin for this use. Example: the pipe is not stressed at these low temperatures.

Pressure compatibility

Radiant systems operate at 10-30 psi typically. PEX-EVOH pipes handle 100 psi at 95°C. The pressure is far below the maximum rating. Example: residential systems rarely exceed 30 psi.

Example: residential floor heating installation

A new home has radiant floor heating throughout. The installer uses PEX-EVOH pipes in the concrete slab. The system runs at 40°C and 15 psi. The pipes protect the boiler and pumps from corrosion.

Example: commercial radiant project

An office building has radiant heating in the lobby. PEX-EVOH pipes are embedded in the concrete. The system connects to a central boiler. The oxygen barrier prevents corrosion in the entire system.

Durability in concrete

Radiant pipes are often embedded in concrete slabs. The concrete has a high pH (alkaline). PEX-EVOH pipes resist the alkaline environment well. The EVOH layer is protected by the outer PEX layers.

Flexibility for installation

Radiant floor pipes need to bend around obstacles. The pipe is flexible and easy to install. It returns to shape after bending. PEX-EVOH pipes are suitable for serpentine layouts.

Standards and certifications

PEX-EVOH pipes meet DIN 4726 standards for oxygen barrier . They also meet ISO 15875 for plumbing . PEX-EVOH pipes are approved for hydronic systems.

Example: retrofit radiant floor

A homeowner adds radiant heating to an old basement. They choose Cross-linked Polyethylene – Ethylene Vinyl Alcohol Copolymer pipes for the project. The pipes go under the subfloor with aluminum plates. The system connects to the existing boiler.

Long-term reliability

Radiant floors are inaccessible once covered with concrete. The pipes must last for decades without leaks. PEX-EVOH pipes have a proven track record of 50+ years.

Final suitability summary

Cross-linked Polyethylene – Ethylene Vinyl Alcohol Copolymer pipes are not just suitable for radiant floor heating. They are the best choice for these systems. The oxygen barrier protects metal components from corrosion. They operate well within temperature and pressure limits. They are flexible and easy to install. They resist the alkaline concrete environment. They meet all relevant standards and certifications. They provide long-term reliability and peace of mind. Example: a wise investment for any radiant floor heating project.
