The average life span of a traditional tank storage water heater is between 10 and 15 years, and some models need to be serviced every six months or so. By contrast, a tankless water heater is more advanced and efficient than a traditional water heater, and it can last for 20 years or more with only minimal maintenance. With correct installation and proper maintenance, a tankless unit can even last as long as 25 to 30 years.

Noritz has designed its tankless water heaters to be direct replacements for traditional tank-based water heaters. These tankless water heaters are perfect for homes of every size, even those with high demand for hot water. By purchasing Noritz tankless water heaters, San Diego homeowners can enjoy the benefits of endless hot water, lower energy bills, and unparalleled dependability. Keep reading to learn how long you can expect your Noritz tankless water heater to last.

How Heat Exchangers Affect Longevity

The longevity of a tankless water heater depends in large part on the type of heat exchanger installed in the unit. For example, if the tankless water heater has a copper heat exchanger, it will probably have a shorter life span. However, with yearly maintenance and proper water treatment, a tankless water heater with a copper heat exchanger can typically last somewhere between 12 and 20 years.

On the other hand, a stainless steel heat exchanger dramatically increases the life span of a tankless water heater. Units with stainless steel heat exchangers typically last for 15 to 25 years. As with units that have copper heat exchangers, proper water treatment and regular maintenance can significantly lengthen the life of an on-demand water heater with a stainless steel heat exchanger, and it can last for 25 to 30 years.

Why Noritz Tankless Water Heaters Last So Long

Noritz is an industry leader in heat exchanger technology with its inclusion of U-bend, 316L austenite stainless steel heat exchangers in its tankless water heaters. This higher grade of stainless steel is much more durable and efficient than materials used in other tankless water heaters. Because Noritz tankless water heaters are manufactured with commercial-grade heat exchangers, they offer long-term reliability that will keep your water heater operating efficiently for decades. 

As long as these high-quality tankless water heaters are cared for properly, they can last an extremely long time.
