x-net C13 dry system Multifunctional lightweight – floor heating especially for renovation.

Underfloor heating for dry screed elements and wet screed. in combination with dry screed elements, the x-net C13 dry system (tubes in the insulating layer) permits especially lightweight floor construction that, in addition, requires minimal time to complete. Even with wet screed, a low construction height and a lower weight over area than the classical wet system (pipes in the screed) can be realised. The new, professional detailed solutions for the tube layout in the manifold connection area make x-net C13 even more application-oriented.

Kermi x-net C13 Trockensystem

System benefits

For use with dry screed elements:

  • Short reaction time
  • Ideal for renovations
  • Low weight
  • No introduction of moisture
  • Low construction height

When used with wet screed:

  • Heating and cooling
  • Lighter weight than classic floor heating-systems (knob and tacker system acc. to design A)
  • Low construction height

Kermi-Plus benefits

  • Low height of the x-net drywall board (25 mm)
  • High load-bearing capacity of the surface thanks to closed structure
  • Three transverse pipe ducts for connecting lines in the head region
  • Easy installation:
    1. Rigid foam insulation made of polystyrene which can be cut with the x-net separating knife
    2. Easy to make additional pipe ducts with the x-net hot cutter
    3. Quick, tool-free length adjustment of the x-net heat-conducting plates
    4. Optimal for pipe laying by one person
  • Perfect protection of the tubes during the rough-in phase of construction. High tube holding force due to Ω contour of the x-net heat-conducting plate
  • Heating technology tested to DIN EN1264 and DIN Certco-certified
  • x-net heat-conducting plate made of steel or aluminium for any given situation

When using x-net aluminium heat-conducting plate:

  • Increased output of 30 % for the same flow temperature
  • Reduction in flow temperature from approx. 3 K with the same heat output, meaning around 7 % energy savings for the heat pump


x-net drywall board 25mm

Kermi x-net C13: Trockenbauplatte 25mm mit 3 quer verlaufenden Rohrkanälen im Kopfbereich
The three transverse pipe channels in the head area allow two heating circuits to be installed in a room without having to create additional pipe ducts.
Kermi x-net C13: Herstellung zusätzlicher Rohrkanäle mit x-net Heißschneider
Additional pipe ducts that may be required, e.g. in front of the distributor, can be created accurately and quickly using the x-net heat-cutter.
Kermi x-net C13: Markierungen auf der x-net Trockenbauplatte 25 mm erleichtern korrekte Positionierung
To assist correct positioning of the x-net heat-conducting plates, there are markings on the x-net drywall board (25 mm).

x-net heat-conducting plate

Kermi x-net C13 Wärmeleitblech: Vergleich Alu vs. Stahl
30% more output compared with the x-net steel heat-conducting plate at the same flow temperature.
Kermi x-net C13: Werkzeugfreie Längenanpassung der x-net Wärmeleitbleche
Tool-free length adjustment of the x-net heat conducting plates by making a simple burr-free break at the pre-punched breaking points.
Kermi x-net C13: Wärmeleitbleich in 3 verschieden große Einzelbleche teilbar
The heat conducting plate can be divided into three separate plates of different sizes (17.5 / 34.5 / 47 cm), thus allowing fast and flexible installation.

x-net detailed solution for pipe guide in the distribution connection area

Kermi x-net C13: Verteilerplatte mit Rohren
Pre-set gap between pipes and load distribution layer: this reduces the floor surface temperature in the distributor area despite close pipe spacing.
Kermi x-net C13: Rohrkanäle exakt und schnell fertigen mit dem x-net Heißschneider
Pipe ducts are cut exactly and quickly using the x-net heat-cutter, which has an x-net Omega cutting tip specially developed for the x-net 25 mm distribution plate. This provides reliable pipe fixing, with particularly high pipe retention strength.
Kermi x-net C13: Querschnitt Omega-Rohrkanal
Omega-shaped pipe duct cut on-site for reliable pipe fixing with a pre-set gap between pipe and load distribution layer.

x-net 5-layer-PE-Xc tube

Kermi x-net C13: x-net 5-Schicht-PE-Xc Rohraufdruck mit Angabe von Restlänge und bereits verbrauchter Rohrlänge
Printed marks on the pipe indicate the remaining length and length already used, allowing optimal utilisation of pipe coils.
Kermi x-net C13: Hohe Flexibilität bei Rohrbiegung
High flexibility allows tight bending radii and reduces the restoring forces in pipe elbows.
Kermi x-net Rohr und Rohrverbinder
Pipes and pipe connectors as defined in DIN 4726 and DIN EN ISO 15875 are tested and monitored regularly by an accredited independent testing institute.

x-net edge insulating strips H 120 mm

Kermi x-net C11: Klebestreifen zur Wandfixierung des x-net Randdämmstreifens H 160 mm
Adhesive strips for wall-fixing of x-net edge insulation strip H 120 mm. Height is matched to the lower floor structure levels of the x-net C13 dry system, ensuring that no adhesive residue is visible later on the wall.
Kermi x-net C13: Extralanger Folienlappen mit x-net Polyethylenfolie T 200
The extra-long protective film with x-net polyethylene foil T 200 allows reliable creation of a screed-separating foil trough.
Kermi x-net C11: Mehrfach-Abreiß-Schlitzung
Multiple tear-off slits for fast tool-free cutting of edge insulation strips without leaving tool marks on the wall plaster.

x-link connection fitting

The combination of a bathroom radiator and underfloor heating is becoming increasingly popular. What was missing was a visually and technically convincing solution for the connection problem.

Using the x-link connection fitting, it is quick and easy to connect the underfloor heating circuit via the bathroom radiator to the existing radiator network.
