How Long Does A Tankless Water Heater Last?
Tankless water heaters are a great upgrade to any home or business that has previously only utilized a traditional tank water heater. Many wonder, however, how long these types of water heaters last, as they can cost more upfront than a traditional tank water heater model. So, if you’re also asking the question of how long does a tankless water heater last, whether due to an aging unit or the consideration of buying one for the first time, read on for the scoop.
Water Quality
There are numerous factors that affect the longevity of a tankless water heater. One such factor, water quality, affects tankless water heater longevity, traditional water heater longevity, and the longevity of nearly all other plumbing components in a home or office. Hard water, for example, contains many particles, like calcium and magnesium, that go on to solidify inside water heaters and other plumbing components. When water quality is an issue, the internal parts of a tankless water heater will undergo much more wear-and-tear, particulate buildup, and even corrosion and clogging, that all go on to contribute to a shorter lifespan.
Brand Quality
As with most manufactured wares out there, the quality of the product is ultimately determined by how well it’s made by its manufacturer. Tankless water heaters are no exception to this rule. A better-built and often more pricey model will almost always offer a longer lifespan than a lesser model or brand.
Installation Location
The location in which a tankless water heater is installed is another significant determining factor in its ultimate life expectancy. When these systems are installed in a more climate-controlled space, such as in a utility or laundry room inside a home, they do not have to work as hard in order to warm the water they are fed. On the other hand, units installed in areas that aren’t as well covered by heating and air systems must work harder and undergo harsher conditions in general.
Fuel Type
The type of fuel that tankless water heaters utilize also tends to be a determining factor in longevity. Electric models tend to run into problems quicker, while gas tankless water heaters usually offer a bit of a longer lifespan. This is due to how these fuel types work inside of these systems and the resulting strain placed on them over time.
Realistic Tankless Water Heater Life Expectancy
In conclusion, the answer to the common question of how long does a tankless water heater last, on average, is 20 years or more. This lifespan can sometimes be extended, however, if the wear they’ve experienced is mainly on parts that are replaceable. Compared to a traditional tank water heater, this is a great increase of 5-10 years of life expectancy.
