TASSU S
• Tassu S heating cable is designed for renovation installation on top of old oors, in concrete structures,
on a plasterboard or in a wooden structure oor.
• The heating cable is not suitable for mounting on a wall.
• The cable loading of the Tassu S heating cable is approx. 10 W/m.
• The minimum laying distance for the Tassu S heating cable is 90 mm.
• The minimum bending radius for the Tassu S heating cable is 40 mm.
• The maximum power per square meter for the Tassu S heating cable installation is 140 W/m2.
Installation on top of an old oor (Fig. B)
1. Old ooring
»Prepare the old ooring according to the oor-
ing manufacturer’s instructions.
2. Adhesion layer (Primer)
»Spread renovation plaster according to the
manufacturer´s instructions.
3. Heating cable
»Installation depth is 20-30 mm.
4. Installation tape or mesh
»Attach the heating cable to a concrete and slab
oor with installation tape or with cable xing
strip XBC1230.
»You can also use a mesh (e.g. a thin wire mesh,
approx. 25x25 mm). Attach the heating cable to
the mesh with cable ties or a similar fastening
method in such a manner that it does not cause
permanent deformation of the cable sheath.
5. Floor sensor in protective tube
»Close the protective tube watertight with a plug,
tape or similar.
6. Screed
»Screed thickness is 30-50 mm when using
gypsum, and 20-30 mm when using concrete.
»Install the heating cable in a medium of equal
thermal conductivity over the whole installation
area.
7. Filler (if necessary)
8. Flooring material
9. Thermostat
Installation in plasterboard oors (Fig. C)
1. Plasterboard layer
»Prepare the layer according to local building
regulations and manufacturer’s instructions.
»Leave an intact layer of plasterboard under
the heating cable. Attach additional strips of
plasterboard to this layer.
2. Heating cable
3. Floor sensor in protective tube
»Close the protective tube watertight with a plug,
tape or similar.
4. Plasterboard strips
»Attach the strips to the base according to
manufacturer’s instructions.
5. Grooves for heating cable
»Lay the heating cable in the grooves.
»Fill the grooves with stone-based plaster.
6. Filler
7. Plasterboard
8. Damp proong (if necessary)
9. Ceramic tile adhesive (if necessary)
10. Flooring material
11. Thermostat
Installation in wooden structures (Fig. D)
1. Thermal insulation
2. Aluminium foil
»Spread aluminium foil over the insulation to
improve heat conduction and prevent the heating
cable from overheating.
3. Attachment mesh
»Spread a mesh between the xing battens for
attaching the heating cable.
4. Heating cable
»Minimum distance to the ooring material is
30 mm.
5. Floor sensor in protective tube
»Install the sensor at the oor joint and oor
material connection point without touching the
cable.
6. Crossing the xing battens
»Notch the crossing points to make them loose,
e.g. 40x25 mm.
»Take also into consideration the durability of
the structure.
»For ame proong put a protective metal plate
where the cables cross the runner.
7. Flooring material
»Use a ooring material suitable for underoor
heating. Check the suitability with the manufac-
turer of the ooring material.
8. Thermostat
»Use a thermal cut-out, if necessary.
