Q 6.1 Floor Heating System
Q.1: Can I cut the Therma Cable heating cable to shorten it?
A.1: NEVER. If the Therma Cable is too long, spread it on the floor in regular
loops. Keep the minimum distance from the walls and between parallel
runs of cable (radius bending of at least 20 mm [¾”] for loops). Be sure
to keep 76 mm (3”) (other spacing option: 100 mm [4”]) between each
heating cable loop.
Q.2: What should I do before choosing the Therma Cable system that’s
right for me?
A.2: Make sure which power source will be used (120 or 240 Vac) to power the
heating cable or mat chosen. There must be a drawing plan to determine
the coverage area to be heated considering the elimination of the fixed
elements including: countertops, vanity, shower, bath, appliances,
wardrobes, toilet, etc. It should also be eliminated from the total surface
area a clearance of between 2’’ and 3’’ wide in respect to the surrounding
walls of the room and fixed elements.
To help you optimize your Therma Cable route running on the floor, we
must need YOUR WORK PLAN WITH ALL RELEVANT MEASUREMENTS OF
THE SURFACE TO BE HEATED by fax at 1 800 662-7801 and an assessment
will be made for this purpose.
Q.3: How do I repair Therma Cable in case of a malfunction?
A.3: First, as a PREVENTIVE measure during installation, test the cable each time
as specified in the installation guide. Also complete the measures’ table.
However, in case of a malfunction, an authorized Ouellet Canada Inc.
repair person will visit to LOCATE the fault and REPAIR it. It is recommended
that you keep spare ceramic tiles or flooring for this purpose.
Q.4: Are there other watt densities per square foot available?
A.4: Ouellet Canada Inc. believes that 12W/sq. ft. (130W/sq. m) at 76 mm
(3”) spacing is the best watt density to optimize comfort and prevent
floor overheating. Therma Cable can also be installed with a 100 mm
(4”) spacing for a 9W/sq. ft. (96W/sq. m). Moreover, the 240V and 120V
systems provide equal heating power per square foot.
Q.5: Can I crisscross, overlap, or touch two heating cables together?
A.5: NEVER. This will cause overheating. Keep cables at least 76 mm (3”) or
100 mm (4”) apart.
Q.6: Can the cable be bent 90°?
A.6: Yes, but make sure the radius bending is at least 20 mm (¾”). Any bending
smaller than this may damage the cable.
