Green Wavin pipe intended for underfloor heating

The green Wavin PERT-EVOH-PERT pipe is a flexible pipe for underfloor heating available in two diameters ø 16 and ø 17 mm and two coil lengths for each diameter. The five-layer construction of the pipe provides excellent protection
EVOH layer against mechanical damage. The green color of the pipe refers to ecological heat sources, such as heat pumps, with which the pipe works perfectly.

Properties of the PERT-EVOH-PERT pipe ensuring quick installation

  • Flexible on curves, which allows for trouble-free changes of direction and turns in underfloor heating .
  • Perfect for coastal areas where the pipe density is highest, pipe spacing up to 10 cm without the pipe breaking when changing direction.
  • It does not lift insulation at the ends of loops and does not tear out clips in corners.
  • Thanks to long coils (200 and 600 m for 16 mm diameter and 200 and 560 m for 17 mm diameter), it minimizes the amount of waste when laying loops.
  • A hole in the box allows the pipe to be unwound even in the absence of a decoiler. It also facilitates the assembly of the coil on the decoiler.

The green Wavin pipe is ideal for heat pumps

The green Wavin pipe for underfloor heating, in addition to the standard diameter of 16 mm, is also available with a diameter of 17 mm. Pipes with a diameter of 17 mm are particularly recommended for systems powered by heat pumps . Thanks to the larger diameter, the heating system made of such a pipe has a larger water capacity, which helps ensure a longer life of the heat pump. A larger charge means a larger heat capacity of the system, which allows the heat pump to start less frequently. All this while maintaining the standard height of the screed.

General guidelines for installation and storage of Wavin green pipe

1. Compliance with installation guidelines

  • Always cut the pipe at right angles to the pipe axis.
  • Calibrate the end of the pipe around the circumference and chamfer it with a Wavin calibrator.
  • Insert the pipe into the connector of the manifold until resistance is felt.

2. Installation temperature

The processing temperature of Wavin underfloor heating pipes should not be lower than -10ºC. The optimal temperature range for the installation of Wavin system elements is from 5ºC to 25ºC. At this temperature, the pipe has the best properties - flexibility and increased resistance to kinking.

3. Sealing

Due to the fact that the PERT-EVOH-PERT pipe is intended for underfloor heating installations and low-temperature radiator heating installations, only connectors for the distributor/ radiator with a ring are used. This connector has an O-ring seal and does not require any additional sealing agents - such as paste, threads or adhesives.

4. Repair and straight connectors

For a ø 16 mm pipe, if it is damaged in the installation, the ideal solution will be a repair connector, which can be used to quickly and efficiently replace the damaged part of the installation. In the case of a pipe with a diameter of 16 mm, the Wavin Tigris M5 telescopic repair connector can be used. Straight connectors are available for pipes with a diameter of 17 mm, which can be used to repair damage.

5. Fixing pipes to insulation

Within the Wavin systems, the most popular methods of attaching pipes to the ground are:

  • fastening to the insulating board with a tacker using mounting clips.
  • pipe mounting in the pressed system panel.

We install the clips at a spacing of 70-80 cm; denser on curves – min. 5 clips. The Alfa Premium tacker is ideal for installing clips, its greatest advantage is its smooth operation - it does not jam even when pressing the clips into the insulation very quickly.

6. Storage

PERT-EVOH-PERT pipes should be stored in the original cardboard packaging or possibly wrapped in foil. Thanks to this, they are protected against mechanical damage and weather conditions. It is allowed to store pipes on the decoiler, but protect them against weather conditions, mainly from sunlight.

7. The negative impact of ultraviolet radiation

PERT-EVOH-PERT pipes should be protected against intense, direct sunlight and ultraviolet (UV) radiation. This applies to the storage of both pipes and finished installation parts. For this reason, outdoor storage should be avoided. Finished installations or their parts should be protected against UV radiation using appropriate protective measures.
