Development and production processes

Quality is a major factor in the development and production of our appliances. A.O. Smith is a trendsetter in the field of advanced water heating products and technologies. A good example developed entirely in-house, is our patented PermaGlas Ultra Coat enameling: a glass protective layer on the interior surface of the steel tank, ensuring maximum corrosion resistance and a long lifetime of the appliance.


The processes by which our appliances are manufactured are compliant with quality standards such as ISO 9001:2008. As a global manufacturer local standards and directives are also applied. CE certification is obviously standard for the entire European market. Supplementary certificates required for eligibility for local and regional subsidy programs are applicable in The Netherlands, France, Belgium and Great Britain.

Custom solutions

One popular option is to obtain support from your local Sales Engineer or, alternatively, our Technical Support department. This support is available starting from the planning and design stages, when important decisions need to be made. We’re also available to discuss your installation and service requirements, when the need arises.
