ELECTRIC HEATING CABLE
CTAV-10, CTAV-18 EN

Twin conductor heating cables CTAV-10/18 are designed for installation in
concrete or into layer of glue and used both for new heating floors and renovated
floors, also for frost protection of outer staircases. Heating cables are laid directly
on the concrete or old tiles in the bathroom, kitchen, room or other premises.
Different flooring requires different heating cables. We recommend:
Recommended heating cable Floor surface
Indoor
CTAV-18 (100-150W/m²) Tiles on concrete: kitchen, room, hall
CTAV-18 (100-120W/m²) Tiles on concrete - F-BOARD oor insulation
CTAV-10 (100W/m²) Wooden oors: laminate, parquet, timber boards.
Outdoor
CTAV-18 (250-300W/m²) Heating of external stairs and staircases

3. The installation of heating system should be done only by approved
specialist.

2. CONCRETE FLOOR HEATING
The system of heating cables can be the main (the only) heating source of
premises but also can supplement other ways of heating - water or electric panels,
replaces. Then we shall arrange system of the “heated oors”.
The heating cables are installed in a free space of oor (not covered with steady
equipment freezer, cooker, kitchen furniture, bath, washing machine, etc.), in 35 mm
layer of the concrete. Using CTAV-18 cable which has 18 W/m power, the distance
between the cable loops (C-C) is 5-15 cm. Such a layer of concrete and the distance
between cable loops is important for evenly spread of heat and helps to avoid the
uctuations of temperature.
The thickness of oor can be reduced by pouring self-levelling compound over
the cables CTAV-18, CTAV-10 or installing cables directly in the layer of tiles adhesive.
The distance C-C is simply to keep using mounting tape (the distance is 25 mm).
The mounting tape is laid in 50-100 cm distance. The consumption of tape is 1-2
m/m2. Tape is xed by nails or glued.
3. FLOOR HEATING BASE ARRANGEMENT
If you want to have the oor giving comfort and heat to your house, rst of all
you have to arrange the base for heating oor (Pic. 1 and Pic. 2).

2. Thermo insulation

4. Thermostat sensor (in sealed
pipe)
5. Heating cable (in layer of adhesives or self-
levelling compound)
6. Damp insulation (in bathrooms)
7. Layer of adhesives or self-levelling compound
8. Tiles or other ooring material
It is very important that construction of heating oors have good thermo
insulation, otherwise big part of heat will be lost. Especially this is important when
unheated cellar or ground is under the oor.
The thermo insulation of vertical edges of heating zones (outer walls) secures
the heat does not ow to the sides, walls or unheated areas. Besides, the vertical
insulation absorbs horizontal expansion of oors because of heating.
ATTENTION! Heating cable cannot touch the thermo insulation material.

4. ACCUMULATED HEATING INSTALLATION
Accumulated heating of oors is designed for heating oors in residential houses,
oces, industrial premises, etc., where is the possibility to use night low tari
electric energy. Heating cables are installed into thick (7-15cm) layer of concrete
(Pic. 3) which accumulates heat during the low tari period.

Usually installed power for accumulated heating is 150-200W/m2.
5. BEFORE HEATING CABLE INSTALLATION YOU HAVE TO
• Check if the product in the package corresponds to one indicated on the
package label.
• Measure the resistance of heating cable and its insulation. Resistance of the
cable has to correspond to the value indicated on the product label (+/- 5%). The
value of resistance has to be not less than 0,5 MΩ.
• Cut the channel in the oor and wall till the thermostat junction box for sensor
pipe and cable connection wires.
• Clean oor from sharp things.

6. HEATING CABLE INSTALLATION
• Fix the mounting tape to the oor.
• Lay the heating cable and x it on the tape keeping the distance between the
loops (C-C).
• Distance C-C = heated area (m2)/ heating cable length (m).
• Put the sensor pipe into channel and seal its end. The end of pipe has to be
between the cable loops, not nearer than 30 cm from the edge of heated area.
ATTENTION! Heating cable (RED) cannot be shortened, crossed or touch itself.

Installation tape is mounted onto clean
surface (concrete) within 0.5 meter intervals.
Cable is installed when xing it on the
installation tape in distance C-C between
cable loops. Picture 5
Minimum bending radius has to be 8
diameters of the cable.
Heating cable has to be xed to the
installation tape using hooks.

• Measure the resistance of heating cable. Its value must correspond to the one
indicated on the label. The data of measurement should be put into warranty
coupon which is on the last page of instruction.
• Draw the layout of laid heating cable and indicate the place of joints (i.e. 30 cm
from the one wall, 50 cm from another).
• Pour the cable with self-levelling compound or cover with tile glue.
• Measure once more the resistance of heating cable and its insulation. The
measured value should correspond to the rst measurement’s value. This value
should be put into warranty coupon.
• Apply the tile glue and lay the tiles or let the self-levelling compound to harden
and then apply any ooring.
WARNING! Always mount sensors in protective pipes to enable easy change
of them.
7. INSTALLATION OF FROST PROTECTION SYSTEM IN STAIRCASES
Ice and snow melting system can be used as eective help against icy and
slippery stairs. We recommend using thermo insulation in stairs, especially if they
are open from bottom and fast freezing. And opposite, in monolithic stairs thermo
insulation is not necessary.
Installed power is chosen 250-300 W/m2. Cables are laid with C-C = 7 cm, or 4
loops of cable in one stair (pic.8).
As the cable is not installed into vertical side of stair, the rst line of cable is laid
as near as possible to the edge of stair for more eective melting.
• Before installation of heating cables clean stairs from sharp things because they
can damage the cables.
• Install cable directly into concrete and cover it with 1-2 cm of concrete or install
directly into layer of tile glue.

8. THERMOSTAT INSTALLATION
• Let adhesive to dry, once more check the resistance of heating cable and its
insulation, connect the heating cable to the thermostat. Now the heating can
be switched on.
• The devices for full disconnection, according to the requirements of III rd
category of overpower, must be included into standard installation.
ATTENTION! In case heating cable is damaged, repair must be done by approved
specialist. Cable should be repaired by connecting it with special joint.
