GE (General Electric) 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, installation, maintenance, and fuel source its lifetime could be anywhere between 1 to 20 years or more.
The first step you should take when determining the water heater’s age is to check the manufacturer’s label on the side of the water heater.
The label will often include pertinent information including:
- Manufacturer Name
- Brand Name
- Manufacture Date
- Model Number
- Serial Number
If you can’t determine the installation date of the water heater, it’s worth checking to see if you’re nearing time for a replacement based on the manufactured date/age. You can use the model number in conjunction with the serial number of the unit in order to determine the water heater’s age. We have compiled a guide of the most popular water heater brands for you to use in the determination the age of the water heater.
