With abundant experience, we warmly welcome you to buy high quality pert underfloor heating pipe for sale here from our factory. Also, pricelist and free sample are available.
PERT underfloor heating pipe is the primary conduit for low-temperature hydronic radiant systems. Installed beneath the floor screed, it circulates 35 to 60°C hot water to deliver uniform upward radiant heat, replacing radiators for whole-home comfort. Manufactured from temperature-resistant PE compound, it offers stable pressure retention and creep resistance under prolonged thermal stress. Heat fusion joints weld pipe and fitting into a single homogeneous structure. These attributes make PERT the world's most widely specified all-plastic radiant heating pipe.
Key Advantages
Leak-Proof and Repairable
Fusion joints match pipe body strength. Post-install damage can be locally repaired by re-fusion without full-loop replacement.
50-Year Lifespan
Immune to corrosion and scaling with zero flow degradation. Service life aligns with building structure. Material is 100% recyclable.
Fast Installation
Flexible coils allow joint-free continuous loops and bend easily around obstacles. Lightweight handling cuts labor time and cost.
Comfort and Efficiency
Radiant heat eliminates drafts and airborne dust while saving 15 to 30% energy over radiator systems. Delivers the ideal warm floor, cool head comfort profile.
Applications and Selection
| 20×2.0mm S5 |
Standard residential branches, fits over 90% of layouts. Also for retrofits and agricultural heating. |
| 20×2.3mm S4 |
High-rise and high-pressure systems needing extra safety margin. |
| 25×2.3mm S5 |
Main lines for large homes, hotels, and offices. |
| 25×2.8mm S4 | Central heating plants and outdoor snow melting, high-pressure thick-wall. |
Selection Guide: Branch circuits use 20mm for optimal resistance and heat output. Main lines and high-flow loops use 25mm. Working pressure above 0.8MPa or water hammer risk calls for S4 series upgrade. Villas and passive buildings should be sized per engineered heat load calculation.
FAQ
Q: PERT or PEX, which to choose?
A: PERT enables fusion joining, is repairable and recyclable, ideal for embedded runs. PEX relies on mechanical fittings, cannot be fused or recycled. PERT wins on install flexibility and lifecycle cost.
Q: Maximum water temperature?
A: 70°C continuous, 95°C peak. Underfloor systems typically run 35 to 60°C, well within rating. For combi-boiler direct feed, specify S4 series and add a mixing station.
Q: Conditions for 50-year lifespan?
A: Water at or below 70°C, pressure at or below 1.0MPa, proper installation per standard. Avoid sustained over-temperature or over-pressure operation.
Q: Do I need oxygen-barrier pipe?
A: Recommended when metal components such as manifold, boiler, or valves are present. EVOH barrier blocks oxygen ingress and prevents corrosion. All-plastic systems can use standard non-barrier pipe.
Q: What customizations are available?
A: Color, coil length, wall thickness, and EVOH oxygen-barrier layer are all customizable. MOQ and lead time vary by spec. Contact us for details.
