The 17th Edition Wiring Regulations are published by The Institution of Engineering and Technology and form the British Standard for the requirements for electrical installations. The 17th Edition Wiring Regulations cover all installations designed after 30th June 2008 and it is a legal requirement for electrical work and systems to comply with them.
The standard is BS7671:2008 and there are many different chapters covering everything from basic wiring requirements through to specialist areas such as electrical systems in boats. Section 753 of the Regulations exclusively covers electric underfloor and ceiling heating, its installation and use.
Section 753 17th Edition Wiring Regulations
Section 753 of the 17th Edition Wiring Regulations introduces the requirements for the installation and safe use of electrical underfloor and ceiling heating, although it specifically excludes use of these systems outdoors for instance as frost or snow protection.
The Section introduces many requirements for the design of heating systems and also includes a list of information that the installer of the system must provide to the end user once they have left. All Heat Mat instructions are written to comply with the legislation and support the installer in their obligations for passing on information to the end user. All Heat Mat systems are 17th Edition compliant, and Heat Mat was the first company to list their systems as such.
All installers of electric underfloor heating should ensure that they are aware of the requirements of Section 753, and that the supplier of the heating system confirms the systems are compliant.
