🌀 PEX & PE-RT Pipes – High-Performance Tubing for Radiant Heating

🌡️ The Flexible Core of Your Home’s Comfort

Choosing the right pipe is the most critical decision in any underfloor heating (UFH) or plumbing project. The PEX & PE-RT Pipes category at Termix.ro features advanced polymer tubing designed for maximum flexibility, thermal resistance, and easy installation. Whether you are laying kilometers of floor loops or connecting a single bathroom, our pipes provide a leak-proof foundation for your system. 🚀

Engineered to withstand high pressures and fluctuating temperatures, these pipes offer a modern, corrosion-free alternative to traditional copper or steel.

✨ Explore Our Advanced Piping Solutions:

🛡️ PEX-a & PEX-b with EVOH Barrier: High-density cross-linked polyethylene featuring a specialized EVOH (Ethylene Vinyl Alcohol) outer layer. This barrier prevents oxygen from entering the heating water, protecting your boiler and pumps from internal rust.
🌀 PE-RT (Polyethylene of Raised Temperature Resistance): A highly flexible, cost-effective alternative to PEX, specifically designed for low-temperature underfloor heating systems. Its "soft" nature makes it exceptionally easy to bend into tight loop patterns.
🏗️ 5-Layer Technology (5L): Our premium pipes feature the oxygen barrier embedded inside the pipe wall (protected by two layers of PE), ensuring the barrier isn't scratched or damaged during rough on-site handling.
💧 Potable Water Certified: Specific PEX variants that are fully certified for drinking water applications, ensuring zero taste or odor transfer and total hygiene.
📏 Multiple Diameters: Available in standard sizes including 16mm, 17mm, and 20mm, with various coil lengths (100m to 600m) to minimize waste on any project size.

📊 Why Choose PEX or PE-RT over Metal?

Zero Corrosion: Polymer pipes cannot rust or pit, even in areas with "aggressive" or hard water. 🛡️
Smooth Inner Surface: Extremely low friction loss ensures higher flow rates and prevents the buildup of limescale or "biofilm." 📉
Shape Memory (PEX): PEX-a pipes have "thermal memory," meaning small kinks can often be repaired with a heat gun, restoring the pipe to its original shape. 🪄
Fast Installation: Long coils mean fewer joints. In underfloor heating, the entire loop is a single continuous pipe with zero connections under the floor. ⚡

💡 Expert Advice from the Termix Team:

Barrier is Mandatory: For heating systems, never use a pipe without an EVOH oxygen barrier. Without it, oxygen will permeate the plastic and cause rapid corrosion of the metal parts in your boiler and manifold. 🚫💨
Bending Radius: When installing floor loops, respect the minimum bending radius (usually $5 \times$ the outer diameter). Using a "bending spring" or pipe tackers helps maintain the shape without stressing the polymer. 📐
Pressure Testing: Always perform a pressure test of 6 bar for at least 24 hours before pouring the concrete screed over your UFH pipes. This ensures total peace of mind before the installation becomes permanent. 📊
