KNOWLEDGE FOR BETTER DECISIONS

Frequently asked questions about hot water and decarbonisation

Where do I register my product?

Please register your product here.

What is the production date of my device?

Using the serial number of your device, it is easy to determine the production date. The first two digits indicate the production year and the next two digits indicate the production week.

The serial number can be found on the device’s nameplate (a sticker on the device).

Example:
If the serial number starts with 2037, then the device was produced in week 37 of 2020, or between September 7 and 13, 2020.

Want to look up the production date directly or more information? Then check out our page on production dates.
You can also watch the video that explains step by step how to read it.

How do I know which water heater is most suitable for my project?

The choice of the right system depends on several factors, such as the required amount of hot water, the desired temperature, and any peak demands within your project. Every situation is unique and requires a solution that fits both technically and economically.

At A.O. Smith, we look beyond the individual unit and focus on the complete hot water solution. Thanks to our broad product range and expertise, we can combine different technologies when needed to create a reliable and sustainable system tailored to your application.
