Keeping up with electric water heating regulations_1

Our industry is covered by many different areas of legislation and there can be lots of acronyms and jargon that can be overwhelming, especially regarding electric water heaters. In order to help our customers currently looking at electric hot water heaters, we’ve compiled a brief overview of some of the key UK regulations.

Any installed water fitting that carries or receives water from the public mains water supply in the UK, must comply with the Water Supply (Water Fittings) Regulations 1999 for England and Wales, the Water Byelaws 2000, Scotland and the Water Regulations Northern Ireland. These require that a water fitting should not cause waste, misuse, undue consumption or contamination of the water supply and must be ‘of an appropriate quality and standard’. It would be highly unusual to find any CE marked water heater that causes any of these issues, but it’s worth bearing this in mind!

KIWA and WRAS

KIWA is one of several independent UK organisations certified to approve unvented hot water storage systems to the requirements of the above legislation, as well as the Building Regulations. KIWA has tested all Ariston electric water heaters to ensure they comply with the necessary criteria, illustrating the quality of our products and providing you with added peace of mind.

Similarly, WRAS (Water Regulations Advisory Scheme) approval demonstrates a material or water fitting complies with Water Supply (Water Fittings) Regulations or Scottish Byelaws outlined above. WRAS Product Approval applies to items such as valves, boilers and showers, demonstrating compliance with requirements and indicating a product is ‘of an appropriate quality and standard’.

Our UK unvented electric water heaters (such as Andris Lux, Andris Lux Eco, Velis Evo Wi-Fi and Pro1 Eco) that come into contact with mains water are KIWA tested and approved to abide by WRAS regulations. As a result, you can rest assured our hot water units offer you exceptional levels of safety and performance.

G3

Part G3 of the Building Regulations refers to hot water supply and systems, detailing the rules that must be followed by hot water heater manufacturers, installers and professional service companies. When installing an electric water heater, although there is no gas connection involved, fitting an unvented system over 15 litres is classified as a “Controlled Service” under UK Building Regulations, so Regulation G3 applies. As a result, the 30-litre versions of our Andris Lux and Andris Lux Eco electric water heaters, as well as all units in our Velis Evo and Pro1 Eco ranges, are supplied with an unvented kit, ensuring compliance with G3.

For smaller units with a capacity of 15 litres or less (such as our Piccolo or smaller Andris Lux models), there is no need for G3 certification, unless any electrical work is also required to comply with Part P.
