Tankless water heaters have become increasingly popular in recent years due to their energy efficiency and space-saving design. However, one common question that homeowners have is: what is the average lifespan of a tankless water heater?

The lifespan of a tankless water heater can vary depending on a variety of factors, including the quality of the unit, how well it is maintained, and how often it is used. On average, most tankless water heaters have a lifespan of around 10-15 years. However, with proper maintenance and care, some units can last even longer.

One key advantage of tankless water heaters is that they do not store water like traditional tank-style water heaters. This means that there is less opportunity for corrosion and rust to develop, which can extend the life of the unit. Additionally, tankless water heaters are generally more efficient than traditional models, which can also help prolong their lifespan.

To ensure that your tankless water heater lasts as long as possible, it's important to follow manufacturer recommendations for maintenance. This may include flushing the unit regularly to remove mineral buildup, checking for leaks or other issues, and having it professionally serviced on a regular basis.

In conclusion, the average lifespan of a tankless water heater is around 10-15 years. By properly maintaining your unit and using it correctly, you may be able to extend its lifespan even further. Tankless water heaters offer many benefits over traditional models, including energy efficiency and space-saving design, making them a great option for many homeowners.
