How long does a water heater last? Lifespan by type and how to read the date
Most gas tanks last 8-12 years and electric tanks 10-15 years. Heat pump models commonly reach 12-15 years. Tankless can reach 18-20 years with service.

Service life is a planning range
Age provides context, while water quality, maintenance, installation, and visible symptoms reveal actual condition.
The table is a planning guide, not a promise for a particular home. Water quality, fuel, installation conditions, demand, maintenance, and the location of the tank all matter. A heater in a protected utility room can show a different pattern from one in a garage or upstairs closet.
| Gas tank | 8-12 years |
| Electric tank | 10-15 years |
| Heat pump | 12-15 years |
| Gas tankless | 18-20 years |
Age is most useful when combined with symptoms. A newer unit with a failed valve can be a repair conversation. An older unit with corrosion, a leaking seam, or repeated component failures deserves a replacement comparison.
The age range also helps with timing. A working heater near the end of its expected range may be worth replacing on a calm schedule, while a younger heater with one serviceable part may be worth repairing. We compare the condition, the location, and the available replacement options rather than using age as the only answer.

How to read the manufacture date
The rating plate and serial number usually reveal the production date once you know the brand's format.
Find the rating plate and photograph the full model and serial number. Do not rely on a partial number or a guessed letter code. The date formats vary by brand and product generation, and the complete label lets us verify the unit before recommending work.
Bradford White
The first letter is the year code and the second letter is the month code. The letter cycle repeats, so confirm the model style when the age is ambiguous.
Rheem
Many Rheem serial numbers begin with four digits that show the month and year. A serial beginning 0821 usually indicates August 2021.
A.O. Smith
Many A.O. Smith serial numbers start with two digits for the year followed by two digits for the week of that year.
Navien
Use the complete serial number from the rating plate. Navien date formats vary by product generation, so we verify it against the model.
Rinnai
Use the full model and serial number on the side rating plate. Rinnai date formats vary, so we verify the production date from both numbers.
Bradford White uses a repeating letter cycle, so its model style matters. Rheem examples can show month and year at the start of the serial. A.O. Smith examples can use year and week. Navien and Rinnai should be checked using the complete model and serial information.
If the label is damaged or partly hidden, photograph the entire side of the unit and the connections as well. The model, fuel, capacity, and installation location help us narrow the identification. Do not remove insulation, controls, or covers just to find a serial number.

End-of-life symptoms
Rust, noise, leakage, and repeated failures carry more weight than the manufacture date by itself.
Moisture at the base or a tank seam
Rust-colored hot water
Rumbling or popping from sediment
Slow recovery or less available hot water
Repeated pilot, element, thermostat, or valve repairs
Corrosion around connections or the tank body
Maintenance can extend useful service, but it cannot reverse a failed tank shell. A flush may address sediment. A valve or heating component may be repairable. A seam or bottom leak means the stored tank itself has failed and replacement is the safe comparison.
Maintenance also has limits when access is poor or when a component has been allowed to fail repeatedly. A service visit should leave you with a clear choice: repair the part, plan a replacement, or monitor a stable condition. It should not hide the age or condition of the tank.

Make a year 10 plan
Local scope, relevant code details, and the practical information needed for this decision.
At year 10, look at the label, service history, corrosion, recovery, and room protection. Compare the likely repair with installed replacement ranges before an emergency. Texting the label gives us the fastest start, and we can discuss a tank, tankless, or heat pump option based on the home's fuel and space.
