EcoSmart® Water age
How to determine the date of production/manufacture or age of EcoSmart® brand Water Heater Systems.
Water heaters in general have an average estimated useful service life of 10-12 years, though water quality, routine upkeep/maintenance, and location of the water heater will all play critical roles in the longevity of these systems.

Year of manufacture is NOT coded within the serial number.
EcoSmart uses sequential serial numbers. You must contact the manufacturer for assistance in determining the manufacture date.
Note the some units include a specific and separate date code label typically located on the side of the unit. The year of manufacture is typically the 3rd & 4th digits of the date code.
In absence of the date code tag, you may be able to use the warranty verification tool from the manufacturer website which can provide the date of registration (if the unit was registered).

Additional Info:
EcoSmart® designed and released a new logo in early 2019. The logo is a blue water drop encasing green continents of the world (see below). If the unit bears this new logo, it cannot be any older than 2019.
