STRUCTURAL INSTALLATION VARIANTS

Installation under ceramic tiling

• The netted heating mat must be installed in a downward position with the heating conductor so that the conductor is protected by the netting during speckling and adhesive is spread more easily with the toothed trowel.
• IMPORTANT: The heating conductor must be surrounded fully by adhesive or the leveling layer.
• A rigid foam support element panel should be used as insulation if necessary (for garages or unheated cellars). These panels consist of extruded polystyrene foam with a cement layer on both sides – available in the building materials trade. The panels must be stuck to the floor screed with flexible adhesive.
• Lay netted heating mat and tiles according to version A or version B.
• In both versions, the adhesive or levelling layer should be processed in a consistency that results in the heating conductor being surrounded completely.

• Lay the ETHERMA netted heating mat.
• Continue to version A/step 3a or 3b or version B/step 3.

On timber floorboards and chipboard

• UNDERFLOOR PREPARATION: For wooden floors, a hard foam support plate must be installed as a substrate, or the chipboard must conform to quality grade V100G – at least 25 mm thick. Seams must be designed with a tongue and groove and must be structurally glued. The plates must be screwed tightly to the substrate.
• The fresh undercoat must be sprinkled with furnace-dried quartz sand (grain size 0.7-1.2 mm).
• It must be ensured that the heating element is installed with a distance of at least 30 mm from conductive materials such as water pipes, for example.

Layout:

• 2 cm-thick hard foam support element plates are screwed to the existing floor with drywall screws. Seal joints.
• Pretreatment for laying tiles with flexible adhesive (also see underfloor preparation)
• Laying the ETHERMA netted heating mat.
• Continue as per version A or version B

Installation under carpet floors, glued parquet or PVC floor covering.

• With these surface coverings, a smooth and level surface must be achieved – this is best suited to liquid levelling compound.
• The netted heating mat must be installed in a DOWNWARD position with the heating conductor so that the conductor is pro-tected by the netting during speckling and adhesive is spread more easily with the toothed trowel.
• The heating conductor must be surrounded fully by adhesive or the levelling layer.
• ATTENTION: For parquet, wooden floors and laminate, the surface temperature must be limited to 28 °C.

On new or existing cement screed

On new or existing cement screed

Layout:

• A liquid levelling layer must be used on floor screed, old ce-ramic floors, anhydrite screed and plaster underfloor.
• Pre-treat underfloor accordingly.
• Lay the netted heating mat; use flexible adhesive selectively in order to fix the netting on the floor and prevent it from being raised.
• Apply liquid levelling compound; 10 mm thick.

Layout:

• A 10 mm hard foam support element plate must be used on wooden floorboards and chipboard. Netted heating mats may not be laid on wood.
• 10 mm-thick hard foam support element plates are screwed to the existing floor with drywall screws. Seal joints.
• Undercoat, undiluted (see also underfloor preparation)
• Lay the ETHERMA netted heating mat; use staples to fasten the netting to the plates and prevent it from being raised.
• Level with liquid levelling compound, 20 mm thick (rapid screed)

Additional installation options

• The netted heating mat must be installed in a downward position with the heating conductor; this ensures that the conductor is protected by the netting during speckling and adhesive is spread more easily with the toothed trowel. The heating conductor must be surrounded fully by adhesive or the levelling layer.

Under marble tiles in mortar bed

Layout:

• In adhesive bed with marble tiles/thin-bed tiling. The netted heating mat is laid on the screed; the thin layer masonry mor-tar is laid with marble tiles as normal.

INSTALLATION

1. Connecting cable
   • Must be protected from mechanical impact using a protective pipe or protective hose.
2. Positioning the sensor
   • Caulk in the sensor cable and connect the protective sensor hose. Ensure that the sensor cannot subsequently be cov-ered with furniture. It is best to place it in front of a door.
3. Laying
   • Beginning at the connection box, the mat is unrolled in accordance with the laying plan and is pressed down. The netted heating mat must be installed in a down-ward position with the heating conductor so that the conductor is protected by the netting during speckling.
4. Cutting
   • The netted heating mat is adapted to the floor plan by cutting the glass netting.
   • ATTENTION! Do not sever the heating conductor.
5. Netted heating mat laying options
   • The netted heating mat can be turned if the flooring layout so requires it. The netting (not the heating conductor!) is cut at the appropriate point in order to do this.

Adjustment instructions

• Use a knife or a scissors to turn or adjust the glass netting; when doing so, ensure that the heating conductor is not damaged or severed.
• When making modifications, ensure – even if just one heating conductor is fed further – that it remains on the glass netting in order to ensure level laying. The netted heating mat may not be shortened. (prevention of hotspots with superior cable)
• When making adjustments directly after the PTC thermistor, ensure that the heating conductor cannot be withdrawn for use as an extension to the PTC thermistor in the protective installation hose. Never use the heating conductor as an extension of the PTC thermistor.

Sensor/connection cable

• IMPORTANT: Ensure that the sensor’s caulked protective hose is positioned be-tween the two heating conductors. The temperature sensor and connection cable are then placed in the hose.

Protective coating

• The netted heating mat is coated with flexible adhesive when laid out. Ensure that you mix the adhesive to the correct consistency so that no trappings of air are created between the heating con-ductor and the adhesive.

Inspecting the netted heating mat

• After laying and completion of the floor-ing, the netted heating mat must be in-spected for throughput, resistance and insulation value, compared with the re-sistance value on the rating plate and en-tered in the inspection record. Deviations of -5 to +10% of the set point value are within the range of tolerance.

Lay flooring

After the protective coating has hardened, the new flooring is laid with flexible ad-hesive.

Inspecting the netted heating mat after completion of flooring
After laying and completion of the floor-ing, the netted heating mat must be in-spected for throughput, resistance and insulation value.

Electrical connection

Netted heating mats are intended for fixed connection in a flush-mounted con- nection box.
A requirement from VDE 0100, part 520: The netted heating mat’s connecting ca-ble (cold lead) must be fed into a conduit pipe. All mats are connected in parallel, whereby total power consumption must be considered depending on which con-trol device is used (10 A or 16 A switching current ).

A ground fault circuit interrupter (30 mA) must be provided as a protective measure. Wiring and connection may be carried out by a licensed electrical company only. DIN VDE 0100, Part 753 must be observed.

Connection of electronic controller

• A terminal box, 150 cm in height, is pro-vided for electronic controllers (floor temperature controllers, combined con-trollers). The sensor is fed into the con-duit pipe; this must be caulked into the screed (or other underfloor).
• An aluminium or copper protective hose is attached to the end of the conduit pipe; the sensor measuring element must be positioned in this protective hose.
• Requirement from EN 60335-1; 7.12.2: A switching device with a contact open-ing width of at least 3 mm is required as a separating device. e.g. switch, fuse, ground fault circuit interrupter.
• There must be an all-pole isolating circuit (for 230 V mats only).

Control via room thermostat

• If the floor heating system is controlled via a room thermostat, a capillary tube controller or floor temperature limiter for service distribution-board mounting must be provided as a maximum tem-perature limiter (own supply line for sensor). A 100/100 socket or larger is required for the capillary tube controller.

Floor temperature adjustment

• Recommended controller default tem-perature setting:
• 36 °C in bathrooms and saunas
• 30 °C in living rooms
• 28 °C for parquet, wooden or laminated floors
• ETHERMA MTS installation kit: 2.5 m installation sleeve SS-12 1 x copper sensor protection tube FSH-12

INSTALLATION

After the tile adhesive or the leveling compound has hardened, but at the earliest after 24 hours (observe the manufacturer’s instructions), the heating can be put into operation and the user instructed.
