PE-RT Floor Heating Pipe FAQ
1. What makes PE-RT floor heating pipe better than traditional materials?
PE-RT floor heating pipe offers superior advantages compared to traditional materials like PEX or copper. The molecular structure of PE-RT provides exceptional thermal memory, allowing the pipe to retain its shape after bending. Its excellent flexibility reduces the need for fittings, minimizing potential leak points. PE-RT is also more resistant to scaling and corrosion compared to metal pipes. The material's high temperature resistance (up to 95°C) makes it ideal for floor heating applications while maintaining a long service life.
2. How should PE-RT floor heating pipe be installed for optimal performance?
For optimal performance, PE-RT floor heating pipe should be installed with proper spacing (typically 150-300mm between pipes) according to the heat load requirements. The pipe must be secured properly to insulation boards using clips or staples before the screed is poured. Maintain a minimum bending radius of 5 times the outer diameter to prevent kinking. Always pressure test the system before covering the pipes. Use appropriate manifold systems with flow regulators to ensure balanced heat distribution throughout all circuits.
3. What maintenance does a PE-RT floor heating system require?
PE-RT floor heating pipe systems require minimal maintenance due to the material's excellent durability. However, we recommend annual checks of the manifold system and pressure gauges. The system should be flushed every 3-5 years to remove any potential buildup in the pipes. Maintain proper water chemistry (pH between 6.5-8.5) to prevent corrosion in system components. Unlike metal systems, PE-RT pipes won't corrode or scale, but other system components may benefit from periodic inspection.

Additional PE-RT Floor Heating Pipe FAQ
4. Can PE-RT floor heating pipe be used with all types of floor coverings?
Yes, PE-RT floor heating pipe is compatible with all common floor coverings including ceramic tile, natural stone, engineered wood, laminate, and even carpet. However, the thermal resistance (R-value) of the floor covering affects system performance. For optimal results, consult with your heating system designer about the appropriate water temperature settings for your specific floor covering. Tile and stone offer the best heat transfer, while thicker wood or carpet may require slightly higher water temperatures.
5. How does the oxygen barrier in PE-RT floor heating pipe work?
The oxygen barrier in our PE-RT floor heating pipe consists of a thin EVOH (ethylene vinyl alcohol) layer that prevents oxygen molecules from penetrating the pipe wall. This is crucial because oxygen diffusion into the heating water can cause corrosion in system components like pumps, valves and boilers. Our multi-layer construction sandwiches this barrier between the PE-RT layers, providing superior protection while maintaining the pipe's flexibility and durability. The oxygen permeability of our pipes is less than 0.10 g/m³ per day, meeting the strictest industry standards.
6. What is the maximum circuit length for PE-RT floor heating pipe?
The maximum recommended circuit length for PE-RT floor heating pipe depends on the pipe diameter and the flow rate required for your specific heating load. For our 16mm pipe (2.0mm wall), the practical limit is approximately 100 meters per loop. For 20mm pipe (2.3mm wall), circuits up to 120 meters are possible. These limits ensure proper hydraulic balance and maintain sufficient flow rates for effective heat transfer. For larger areas, multiple circuits connected to a properly sized manifold are preferred over exceeding these length recommendations.
