Product specifications and details
The floor heating system is designed exclusively for interior floor heating. The system is not designed for snow
melting or any other outdoor uses; it is mainly designed to complement a building’s primary heating source by
serving as a secondary (floor warming) or primary room heat source (radiant floor heating);
This heating system, is a cable made of a twin conductor with a 10 feet cold lead.
The heating cable consists of a resistance-heating element insulated with Fluoropolymer (FP) having high
dielectric strength and high temperature withstand ability, which makes the heating cable safe. A metallic
sheath is provided to give additional mechanical strength and provide ground path. A final outer jacket of PVC
or Fluoropolymer is given to make it sturdier and provide corrosion protection. The hot and cold junction
is uniquely designed to make it fool proof.
These are available in a wide range of capacities and length to suit your requirements.

Selection of floor heating system
Selection of floor heating system will depend on the application.
As a general guideline, we recommend installation at a maximum of 12 watts per Sq.ft. for heating and comfort
applications.
Depending on the claimed result, the cable system can also be used in 9 watts per Sq.ft. applications. To ensure
optimal heating results, please contact a qualifed individual.
Wet areas (in locations subject to saturation with water) like showers, saunas and steam rooms, bathrooms, etc:
12 watts per Sq.ft. The UL listing for this product does not cover use in wet location in the United States.
Please note the above-indicated values are meant as a general guide, actual requirement will depend on insu-
lation levels, floor construction, type of floor coverings, ambient temperature, movement of the people etc.
Note: The floor heating system can be installed under a shower floor only if the floor is ceramic or natural stone.
A waterproof membrane must be used to maintain the heating cables in a dry environment. The manufacturer recom-
mends using a separate cable for the shower area. The UL listing for this product does not cover use in wet location in
the United States.

Critical information
1Heating cable must not touch, crossover or overlap itself at any point. (Please use strapping to avoid
bunching or crossover of cable). This could cause the cable to overheat.
2Heating cable cannot be cut.
3The heating cable length cannot be altered in any circumstances. This may cause over heating resulting in
damage to the cable.
4Take precautions to avoid damage to the heating cable during installation, due to dropping sharp objects
or stepping or careless pouring of concrete or banging the trowel on the heating cable while applying cement
mortar for tiling/flooring. In case of remodeling of floors, make sure that old mats/cables are removed before
you lay new heating cables.
5Heating cables should be separated from other heat sources such as floor luminaries and chimneys.
6Do not install the heating cable below -15 °C (5 °F) ambient temperature.
7Minimum bending radius of the under cable while laying shall not be less than 1 inch (25 mm).
8If Thermal Insulation Boards of adequate thickness is used, please ensure the item has typical R Value
of 0.027 or less.
9The cold lead, normally 10 feet long, can be cut/extended to suit the location of the electrical power
connection box.
10 Floor thermostat sensor location shall be centered between two adjacent runs of heating cable.
Do not locate oor thermostat sensor closer than 1 inch to heating cable or allow to overlap any other
cable.
11 Maximum limit of the temperature setting on the thermostat should not exceed 30 °C (86 °F).
12 Check the main voltage and wattage of the heating cable as per the selection made. These are marked
on the label of the product.
13 Keep the power leads conduit separate from the sensor cable conduit.
14 It is highly recommended to connect the Cablecheck during the installation to warn about accidental damage
to the heating cable or lead wires.
15 Incase GFCI trips during normal operation, and cannot be reset, there is likely a fault in the cable. No attempt
should be made to re-energize the heating cable. GFCI must not be bypassed in any circumstances.

Thermal insulation
The insulation levels of a floor will affect both the performance & running costs of floor heating system.
The thermal insulation reflects the heat upwards into the floor tile instead of allowing heat to penetrate into the
subfloor and keeps the floor warmer for longer time. While installing the floor heating system, user should install
adequate thermal insulation below it. In cases where the floor heating system is being installed over large areas,
insulation boards will greatly reduce warm-up times & running costs.
When floor heating systems are installed on a concrete slab, we strongly recommend adding a layer of insulation
to the slab prior to installing the heating cables. Adding insulation on top of the concrete slab or board, and
beneath any floor heating system will allow a greater percentage of heat generated to transfer to the flooring
surface.
The heating cable system is approved for the following types of installation:
• Onasuboor
Important: The subfloor material in contact with the heating cable must be able to withstand
a temperature of at least 90 °C (194 °F).

fixed objects such as appliances/baths/kitchen units, etc.) and required watt density for your room. Now calculate
total required output by multiplying area x watt density required for the room. Choose nearest suitable wattage
cable from the available range. When calculated size required is between two sizes of offered cables, select the
smallest of the two.

Each cable’s length is listed in the product selection guide; combine the cable lengths if more than one is being
used. It is recommended that you cut out a measuring template out of cardboard representing the distance
between the cable. You will then be able to place this template next to a cable in order to determine where the
next run should be placed.
We recommand the installation of the cable at a spacing of 3 or 4 inches for an uniform floor temperature.
