1. Concrete heating cable OWC-M Series
1.1 General information
The concrete heating cables, series OWC-M include plastic mats of heating cables combined with an electrical
connection which can be connected to an electrical power source. This system is typically referred to as a
series heating cables set in accordance with the Canadian Electrical Code.
Installation must meet requirements specified by the following codes, when applicable:
- Canadian Electrical Code (CSA C22.1)
- American National Electricity Code (ANSI/NFPA 70)
- Any additional national or local installation code
In order to avoid any risk of electrical shocks,
always make sure the power from the electrical supply
circuit is turned off before handling the cables.
1.2 Critical information
- The OWC-M product is a system intended to heat a building either as a back-up heating system for a specific
room (floor control) or as the main heating system for a specific room (ambient control with floor limit).
Note: Installations using the OWC-M system for ambient control with floor limit only, see section 3.
- The OWC-M concrete heating cable system is designed and approved for interior heat (dry and humid
environments) as per specifications from the Canadian Electrical Code.
- The OWC-M concrete heating cable system is not designed for snow clearance applications or any other
exterior applications.
- The OWC-M concrete heating cable system can be installed under interior partitions, staircases, showers
and other sanitary fixtures, if clearances from drains and other fixed obstacles (fixed in concrete) are
adhered to and provided the system is used with a temperature sensor which regulates the temperature
of the concrete slab (see the following section for clearance guidelines).
- Floor temperatures will vary depending on floor insulation and characteristics. Maximum temperatures for
the floor and the room depend on various factors such as the type of insulation present in the room, the slab,
the number of windows, type of floor covering selected, etc...
- The OWC-M concrete heating cable system must be completely encased in concrete.
- The OWC-M concrete heating cable system must be installed by a certified electrician who is familiar with
the proper assessment of power strength requirements and risks associated with installation requirements,
as well as the construction techniques required for the installation and usability characteristics of the OWC-M
concrete heating cable systems.
- The OWC-M concrete heating cable system is but one step in the construction of a floor. Each building trade
involved is responsible for its own contract stipulations and must ensure that the work performed immediately
before their work segment begins has been completely and adequately finished, all according to good engi-
neering practices. Everyone is a stakeholder in the installation process and the onus of responsibility
rests equally on every individual.
