Knowing how old your water heater is can be helpful when planning for replacement and knowing when you're better off replacing the unit instead of putting money towards repairs. In most cases, if a water heater is more than 10 years old you should consider replacement. As water heaters enter their second decade the risk of developing leaks increases, which can potentially cause damage to your home.
You can find the age of your water heater by looking for the serial number on the manufacturer’s sticker near the top of the water heater. The serial number contains the date that the water heater was manufactured. It will not be in a standard date format, but will have a date code such as "G062052658".
G is for the month and G is the seventh letter in the alphabet, so it represents the seventh month, July. Next, the first two digits of the serial number are 06, which represents the year, 2006. So this water heater was made in July 2006. Each manufacturer uses a similar date code, but they may vary – so check the manufacturer’s website to learn more.
