about how long does a hot water heater last
Clue #1: Age. The older the water heater, the more likely it is to break down. As a general rule, a tank type water heater will last, on average 8 to 12 years. With proper maintenance and a little luck, you may be able to nearly double the lifespan of your water heater. But sometimes even with the best care, a water heater will need to be replaced after only a few years.
