Most water heaters have a lifespan of around 8-12 years. But it’s important to keep in mind that this lifespan can be shortened if the heater is not properly maintained.
If your water heater is older than 8 years, you may want to start considering a replacement. And if you’re noticing that your water is taking longer to heat up, or if your energy bills have been increasing, then it’s likely time for a replacement.
If you’re not sure whether it’s time for a replacement, please consult with a professional technician. They will be able to inspect your heater and tell you what needs to be done in order to extend its lifespan.
