Short answer: yes
PEX EVOH pipes are an excellent choice for snow melting systems. They handle the temperature requirements. The EVOH layer protects the system from corrosion. Example: heated driveways and walkways.
Temperature requirements
Snow melting systems use hot water or glycol at 40-60°C. The pipe handles up to 95°C. This provides a large safety margin. PEX EVOH pipes are well within their temperature limits.
Pressure requirements
Snow melting systems operate at 1.5-3 bar (22-44 psi). The pipe handles much higher pressures. Even at 60°C, it handles 10+ bar. PEX EVOH pipes have a huge pressure safety margin.
Oxygen barrier protection
Snow melting systems have metal components. Boilers, pumps, and manifolds need protection. The EVOH layer prevents oxygen from entering. PEX EVOH pipes protect the entire heating system.
Freeze protection
Snow melting systems use glycol-based antifreeze. The pipe is compatible with glycol. This prevents freezing in the system. PEX EVOH pipes can be used with glycol.
Embedment in concrete
The pipe is often embedded in concrete or asphalt. The pipe must withstand the alkaline environment. PEX EVOH pipes are compatible with concrete. Example: a durable, safe embedment.
Example: residential driveway heating
A home has a heated driveway to melt snow. PEX EVOH pipes are embedded in the concrete. The pipe carries hot water at 45°C. Example: a safe, snow-free driveway.
Example: commercial walkway heating
A commercial building has heated walkways. PEX EVOH pipes are used for the system. The pipe is embedded in the concrete. Example: safe, slip-free walkways for customers.
Example: airport ramp heating
An airport uses a snow melting system. PEX EVOH pipes are installed in the ramp. The system operates at 50°C. Example: a reliable, efficient snow removal system.
Installation considerations
The pipe is laid in a serpentine pattern. It is secured to rebar before concrete pouring. PEX EVOH pipes installation is similar to underfloor heating.
Pressure testing before pouring
Test the system before concrete is poured. Pressurize to 1.5x working pressure. Check for leaks at all joints. PEX EVOH pipes must be tested.
Final snow melting summary
PEX EVOH pipes are fully suitable for snow melting systems. Temperature (40-60°C) and pressure (1.5-3 bar) are well within limits. The EVOH layer protects against corrosion. The pipe is compatible with glycol for freeze protection. It can be embedded in concrete or asphalt. Installation is similar to underfloor heating. PEX EVOH pipes are an excellent choice for snow melting applications. Example: a reliable, long-lasting snow melting solution.
