Electric space-heating systems
62-200 Electric space heating
Rules 62-202 to 62-226 apply to fixed electric space-heating systems for heating rooms and similar areas.
62-202 Temperature Control
(1) Each enclosed area within which a heater is located shall have a temperature control device.
(2) Manually operable controls for electric heaters in bathrooms shall be located at least 1 m from the bathtub
or shower stall, this distance being measured horizontally between the control and the bathtub or shower
stall, without piercing a wall, partition or similar obstacle.
(3) If the condition in Subrule (2) is not practicable, be located not less than 500mm from a bathtub or
shower stall and be protected by a ground fault circuit interrupter of the class A type.
62-204 Connections to branch circuit conductors
(1) A cable set or heating panel used for interior space heating shall have non-heating end leads for
connection to branch circuit conductors.
(2) For the heating panel referred to in Subrule (1), the non-heating end leads shall be permitted to be
attached at the time of installation in accordance with the manufacturer’s instructions.
62-206 Proximity of other wiring (see Appendix B)
Wiring of other circuits located
(a) above heated ceilings shall be spaced not less than 50 mm above the ceiling and shall be considered as
operating at an ambient temperature of 50 °C, unless thermal insulation having a minimum thickness of
50 mm is interposed between the wiring and the ceiling;
(b) in heated concrete slabs shall be spaced not less than 50 mm from the heating cables and shall be
considered as operating at an ambient temperature of 40 °C.
62-208 Installation of central units
(1) Central units shall be installed so that there is reasonable accessibility for repair and maintenance.
(2) Central units shall be installed
(a) in an area that is large compared with the physical size of the unit unless specifically approved for
installation in an alcove or closet; and
(b) to comply with the clearances from combustible materials as specified on the nameplate.
62-210 Wattage of heating panels and panel sets
In accordance with the manufacturer’s instructions and Rule 62-214, the heating portion of the heating panels
and panel sets, when in contact with gypsum board or plaster lath or when embedded in plaster, shall not have
a watt density that will produce an exposed ceiling surface temperature in excess of the limiting temperature of
the ceiling finish materials used.
62-212 Location of heating panels or heating panel sets
(1) The heating portion of heating panels or heating panel sets shall not be
(a) installed in or behind any wall surface, nor in any location where it may be subject to mechanical
injury either during or after construction; or
(b) run through walls, partitions, floors, or similar portions of structures.
(2) The heating panels or heating panel sets shall be permitted to be in contact with thermal insulation but
shall not be run in or through thermal insulation.
62-214 Installation of heating panels and heating panel sets
(1) Field-made connections necessary to assemble heating panel sets shall be permitted to be inaccessible
provided that they are accessible before ceiling finishing materials are applied and the connectors and
enclosures are part of the heating panel sets.
(2) Nailing or stapling of the heating panels and heating panel sets to the ceiling or to the floor joist, headers,
or nailing strips shall be done only through the unheated strips provided for this purpose.
(3) Heating panels and heating panel sets shall not be cut through or nailed through any point closer than
6 mm to the element.
(4) The heating portion of the heating panels and heating panel sets shall not be installed closer than 200 mm
to any outlet to which a lighting fixture or other heat-producing equipment is liable to be connected.
(5) Heating panels and heating panel sets shall not be installed above or below cupboards, walls, or other
obstructions.
(6) Heating panels and heating panel sets shall be permitted in ceilings and below floors of clothes closets if
they are provided with an independent temperature control.
62-200 Electric space heating
