2.3 Resistance tests
Using a multimeter, measure the OWC-M cable resistance at each stage of the installation and note the values
in the measurement chart on the electrical panel label available in the envelope provided with the product.
Dangerous test. For the warranty to be applicable,
you must fill the measurement chart and ensure
that 8 measurements have been correctly recorded.
The system’s cable resistance must be determined by a certified
electrician using the following method:
- Use only a calibrated multimeter.
- Measure the resistance at the loose end of the cold lead between
the two power conductors.
- Record the value measured in the measurement chart.
- Ensure the integrity of heating cables by comparing the value
measured with the value specified on the cold lead label.
- If the value measured is null or very different from the resistance
rating at any stage of the installation, postpone the work and
contact Ouellet Canada’s specialists at 1 800 463-7043.
3.3 Typical floor coverings
Typical floor covering
Thermal resistance
R RSI
Vinyl tiles 0.20 0.035
Linoleum 0.22 0.039
Ceramic 0.25 0.044
Low-pile carpet 0.70 0.123
Parquet flooring 0.70 0.123
Floating floor 10 mm to 16 mm (3/8” to 5/8”) 0.70 0.123
The thermal resistance of any floor covering must
not exceed R = 1.0 (RSI = 0.246). There is no thermal
insulation limit under the floor.
IMPORTANT : Consult floor covering manufacturers when assessing a heated floor system’s compati-
bility with engineered-type hardwood floors, laminate floors, vinyl-covered floors or concrete floors with
glued linoleum covering.
