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 [3/4”] 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 :
Sketch a plan to determine the surface area. We can help optimize your
work plan. Fax it to us at 1 800 662-7801.
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 (3/4”). Any
bending smaller than this may damage the cable.
6.2 Installation
Q.7 :
Can I install one Therma Cable system on top of another?
A.7 :
NEVER. The system will overheat. Heating power must not exceed
12W/sq. ft (130W/m
2
).
Q.8 :
Can Therma Cable be used for exterior snow melting?
A.8 :
No.
Therma Cable
is designed to provide comfort and heating in indoor
residential applications only.
Q.9 :
Is a GFCI necessary?
A.9 :
A GFCI is required in the bathroom. It is recommended for all other rooms.
Q.10 : Is a floor sensor necessary?
A.10 :
Yes, to control floor surface temperature so that it does not exceed the
floor covering's maximum temperature tolerance.
Even if it is not an obligation to use a floor sensor when using the system
with an ambient thermostat, Ouellet Canada Inc. recommends the use of
a floor sensor.
