3. Heating options
The OWC-R concrete heating cable system is designed to maximize two different comfort objectives:
1. Floor control: used as a back-up heating source (surface heating). Will provide year round warm
and comfortable floor surface.
2. Ambient control with floor limit: used as the main heating source (ambient heating). Will provide
occupants with surrounding and uniform heat. It is important to ensure that heat loss in any room does
not exceed the thermal capacity of the installation and to follow all provisions outlined in the following
paragraphs for these types of installation.
IMPORTANT: Because of environmental specifications which are outside Ouellet Canada Inc.’s control,
such as thermal insulation, available surface, emittance of floor covering, heat losses, etc., installation of
a heated floor, regardless of how precisely it is performed, cannot guarantee an entirely uniform surface
temperature. Therefore, Ouellet Canada Inc. may not be held responsible for any comfort inadequacies
such as a cold area on the floor which may result from deficient parameters. Ouellet Canada Inc.’s
responsibility is thereby limited to the adequate performance of its products.
3.1 Floor control
Comfort heating system, provide back-up heating to the main heating system. This type of heating method will
maintain a comfortable, warm floor covering at all times. Simply unroll the OWC-R concrete heating cable and
cover the entire room to be heated. It is important however to adequately insulate the ground underneath the
concrete cables. This insulation will ensure the least possible heat loss at the bottom level. For this type
of configuration, the concrete heating cable must be connected to a suitable temperature control device
(see section 5) and must be paired with a floor-type heating mode and temperature sensor. The sensor must be
installed in accordance with instructions and be connected to the heated floor temperature control device.
