As is the case with any appliance, water heaters do not last forever. So, how long can you expect a water heater to last, and are there any factors that will reduce its lifespan?


Simply put, the average water heater will have a lifespan of about 10 years. There are, however, various factors that will change this such as the amount of water it has to heat up. Naturally, the more it is used, the harder it works which will increase the wear and tear placed on it.


How and where a water heater is installed plays a major role when it comes to estimating its life span. Some homeowners want to keep costs low and so attempt to install the heater themselves, this can be a mistake, though, as many find it a lot harder than they realized, especially if it is a tankless gas heater. The location of the water heater is also important. It should be placed upright and in a well-ventilated space. Avoid installing it in an area prone to flooding as this will make it more vulnerable to rust. When choosing the location for your water heater, you should also keep in mind the need for future repairs and maintenance and select an area that is easy to access.


If you are currently shopping around for a water heater it’s good to remember that you get what you pay for. In general, the more money you pay, the better the quality. The length of the warranty can also give you an idea of how long it will last. Usually, if the warranty is for a long time, the water heater will also last longer.
