How do I tell the age of a Whirlpool water heater from the serial number?
Wednesday, September 12, 2018
Whirlpool water heaters are manufactured by Craftmaster, and their coding system is that the first two numbers of the serial number are the year of manufacture. So the serial number of the water heater data plate in the photo below (circled in red) indicates that the water heater was manufactured in 2005.
To determine the age of another manufacturer/brand of water heater, go to How do I determine the age of my water heater?
To find the age of other home components, go to How can I find out the age of a roof? and How do I determine the age of an electrical panel? and How do I determine the age of my air conditioner? For life expectancies, visit What is the average life expectancy of the components of a house?
