PEX pipe - for wall-ceiling heating - 12x2mm - 240m IVAR.PE-Xc-ST

Product detailed description

Wall and ceiling heating systems are commonly used in residential and commercial buildings to provide even and efficient thermal comfort. These systems rely on the uniform distribution of heated water through a network of pipes embedded in the structure. The IVAR PEX pipe is specifically designed for such applications, where the pipe must withstand varying temperatures and pressures while maintaining long-term integrity. Installers working with these systems must ensure correct sizing, secure connections and compatibility with other components to achieve optimal performance.

The pipe is typically installed in drywall or ceiling cavities, where space constraints and thermal conductivity are key considerations. The flexibility of PEX allows for easier routing around obstacles and through tight spaces. The oxygen barrier in the pipe prevents the diffusion of oxygen into the system, which can otherwise lead to corrosion in metal components such as radiators or valves. This makes the pipe suitable for closed-loop systems with mixed metal components.

Technical parameters

Installation and connection

Installation of the IVAR PEX pipe requires careful planning and adherence to technical guidelines. The pipe is connected using the IVAR.TP 4410 crimping tool, which ensures a secure and leak-free connection. The nominal diameter of 12x2mm must be matched with compatible fittings and valves to maintain system integrity. During installation, it is important to avoid sharp bends or kinks in the pipe, as these can restrict flow and reduce efficiency. Installers should also ensure that the pipe is properly supported to prevent sagging or mechanical stress over time.

Compatibility and accessories

This PEX pipe is designed to be used with the IVAR.TP 4410 crimping tool for secure connections. It is compatible with standard heating systems that use cross-linked polyethylene piping and require an oxygen barrier. Additional components such as manifolds, valves and insulation materials may be required to complete the installation. The pipe is suitable for use in radiant heating systems where a closed-loop configuration is necessary to prevent oxygen ingress and corrosion.

Technical background for designers

The IVAR PEX pipe is made of cross-linked polyethylene, a material known for its flexibility, durability and resistance to thermal expansion. The oxygen barrier layer prevents the diffusion of oxygen into the system, which is critical for systems containing metal components. The pipe is designed to be part of a radiant heating system, where it is embedded in walls or ceilings to provide even heat distribution. The service life and efficiency of the system depend on correct installation, proper insulation and the use of compatible components.

Service and operation

During operation, the system should be monitored for signs of leaks, pressure drops or reduced heat output. The oxygen barrier should be intact to prevent corrosion in the system. While no specific service intervals are provided in the technical data, regular visual inspections and pressure tests are recommended to ensure long-term performance. Any issues with the system should be addressed promptly to prevent further damage.

Frequently asked questions

Can the IVAR PEX pipe be used in open heating systems?
No, the pipe is designed for closed-loop systems where an oxygen barrier is required to prevent corrosion. It is not suitable for open systems where oxygen ingress is expected.

What is the maximum operating temperature for this PEX pipe?
The pipe is rated for operation at up to +90°C with a nominal pressure of PN 6. At lower temperatures, the pressure rating increases to PN 10 at +60°C.

Is the IVAR PEX pipe compatible with copper fittings?
Yes, the pipe can be connected to copper fittings using the IVAR.TP 4410 crimping tool. The oxygen barrier ensures compatibility with mixed metal systems.

Can the PEX pipe be used for both heating and cooling applications?
Yes, the pipe is suitable for both heating and cooling systems, provided that the operating temperatures and pressures are within the specified limits.
