Introduction
The particular requirements of part 7 supplement, modify or supersede the general requirements of
the other parts of HD 384.
The numbers following the particular number of section 753 are those of the corresponding parts,
chapters or clauses of HD 384.
The absence of reference to parts, chapters or clauses means that the general requirements of
HD 384 are applicable.
753 Floor and ceiling heating systems
753.1 Scope, object, fundamental principals
753.1.1 Scope
This standard applies to the installation of electric floor and ceiling heating systems which are
erected as either thermal storage heating system or direct heating system. It does not apply to the
installation of wall heating systems.
NOTE A ceiling located under the roof of a building down to a vertical height of 1,50 m measured from the finished floor
surface is also regarded as a ceiling within the meaning of this standard.
753.1.2 Normative references
NOTE Normative references to international publications with their corresponding European publications are listed in annex ZA.
753.2 Definitions
For the purpose of this Harmonization Document, the following definitions apply:
753.2.1
thermal storage floor heating system
heating system in which, due to a limited charging period, a restricted availability of electrical
energy is converted into heat and dissipated mainly through the surface of the floor to the room, to
be heated with an intended time delay
753.2.2
direct heating system
as floor or ceiling heating system denotes a heating installation which generates heat from electrical
energy and dissipates it to the room to be heated, with a response time being as low as possible
753.2.3
complementary floor heating
direct heating system integrated into the floor construction e.g. in the border zones close to outer
walls which complements the heat dissipation of a thermal storage floor heating system
753.2.4
heating-free area
unheated floor or ceiling area which is completely covered when placing pieces of furniture or kept
free for built-in furniture
753.2.5
heating cable
cable, with or without a screen or metal sheath, for a fixed heating system

HD 384.7.753 S1:2002 – 4 –
753.2.6
flexible sheet heating element
heating element consisting of sheets of electrical insulation laminated with electrical resistance
material, or a base material on which electrically insulated heating wires are fixed
753.2.7
heating unit
heating cable or flexible sheet heating element with rigidly fixed cold leads or terminal fittings which
are connected to the terminal of the electrical installation
753.2.8
cold lead
insulated cable or cord intended to connect the heating unit with the electrical installation
753.2.9
self limiting heating cable
cable to EN 50019 which cannot exceed 70 °C and which does not require cold leads for connection
to the electrical installation
753.4 Protection for safety
753.41 Protection against electric shock
753.412 Protection against direct contact
753.412.3 Protection by obstacles
Protection by obstacles is not applicable.
753.412.4 Protection by placing out of reach
Protection by placing out of reach is not applicable.
753.413 Protection against indirect contact
753.413.1 Protection by automatic disconnection of supply
As disconnection devices RCD with a rated residual operating current not exceeding 30 mA shall be
used.
753.413.1.6 Supplementary equipotential bonding
Where a conductive sheath or grid above the floor heating elements or under the ceiling heating
elements is provided, it shall be connected to the protective conductor of the electrical installation
by equipotential bonding conductors.
NOTE In the case of heating units which are delivered from the manufacturer without exposed-conductive-part a
conductive sheath or grid may be provided as exposed-conductive-part above the floor heating elements or under the
ceiling heating elements.
753.413.2 Protection by using equipment of Class II construction or equivalent insulation
Circuits supplying heating equipment of class II construction or equivalent insulation shall have
additional protection by the use of RCD with a rated residual operating current not exceeding
30 mA.
