How long is the average lifespan of an A.O. Smith water heater?

The average lifespan of an A.O. Smith water heater is approximately 10-12 years. However, this can vary depending on several factors such as the model, usage patterns, maintenance, and water quality. Regular maintenance, including flushing the tank annually and checking for any signs of corrosion or leaks, can help extend the life of your water heater. Additionally, using a water softener or installing a water heater with a scale prevention system can minimize the potential damage caused by hard water minerals, increasing the longevity of your unit. It is important to note that proper installation and professional servicing can also contribute to the overall lifespan of an A.O. Smith water heater.
