Kenmore water heater life expectancy
Many homeowners want a Home Inspector to predict how long their water heater will last.  This is simply impossible and beyond the scope of a Home Inspection — depending on the model, maintenance, and fuel source its lifetime could be anywhere between 2 to 20 years or more.
If you can’t determine the installation date of the Kenmore water heater, it’s worth checking to see if you’re nearing time for a replacement based on age.  Since finding the date of installation isn’t always straightforward, we came up with the handy guide of all known water heater manufacturers to help you decode your water heater’s serial number.
