The answer to this question depends on the nature of the water heater and its use. This article will discuss the various signs of ageing in a water heater, the different choices available to you and advice on your tank.
As for a electric water heater (..., 30, 40, 60, 100, ...) gallons of good quality, the average service life ranges from 10 – 12 years. It's important to emphasize the words “good quality”, because a basic water heater is not equipped with the same materials, which reduces its life expectancy. It's obvious that some water heaters will stop working before 10 years, while others will work like new after 15 years, for example.
If you don't see any of these signs and your water heater is 10 to 12 years old, we suggest you consult your contract with your insurance company to guide you in your decision. Some insurance companies will not reimburse damage if your tank has exceeded the age limit set out in your contract. In condos and apartments, it's not uncommon to be forced to change your tank as a preventive measure after 10 to 12 years.
Then, if you don't have any restrictions, it's time to make a decision. You can choose between preventively replacing your water heater when it reaches 10-12 years of age, or waiting until it stops working. On the other hand, if you wait until it stops working, there's a greater risk of the water heater breaking through due to rust, which could dirty your floor. Then you run the risk of running out of hot water until we can come and change your water heater (which shouldn't take too long!).
