What is the lifespan of a hot water heater?

Answer 1

As a rule of thumb, 10 to 15 years is the expected useful lifetime. If yours is older than that, you need to replace it before it's too late.

This all depends on whether the hot water heater has been installed correctly and whether the maintenance of it has been kept up to date. A well looked after hot water heater can last for many many years. A hot water heater is the same as a car, because if you maintain your car with regular services, it will be in good running order and last for years, its the same concept with a hot water heater.

A secret to those not in the know, to help your ELECTRIC hot water heaters lifespan even more, make sure that the anode is replaced every 2 years, 95% of people who own hot water heaters never replace the anode resulting in burst hot water heaters and hot water heaters which don't last very long, replacing a hot water heater is expensive, replacing the anode every two years is not. Be wise.
