Factors That Affect Tankless Water Heater Lifespan

Tankless water heaters are the go-to option for homeowners who prefer convenience, energy-efficiency, and cost-effectiveness over traditional water heaters. These units can last for several years without giving any significant issue if homeowners take proper care of them.

However, tankless water heaters are not indestructible. They can wear down and experience breakdowns over time due to various factors. Below, we discuss some factors that impact how long a tankless water heater will last:

Frequency Of Use

Water heaters, like most other appliances, can wear down from everyday use. The more frequently a tankless heater is used, the more often it sustains wear and tear. Generally, a tankless water heater can last between 10 and 15 years with regular maintenance and proper operation.

However, if a household has a higher hot water demand, the tankless water heater may struggle to keep up with constant workloads. In such cases, the unit may experience more faults, and its lifespan may shorten.

Some tips to reduce the workload on your tankless water heater include:

  • Taking short showers- long, hot showers can put a lot of strain on your tankless water heater. Shortening your showers can help reduce the workload the unit has to handle.
  • Using lower water temperatures- high water temperatures will typically require more hot water to be produced. Setting your water temperature to a lower setting can help reduce the workload on your unit.

Water Quality

Water quality can also impact the lifespan of a tankless water heater. Different types of water contain different minerals, some of which can corrode or wear down the interior of the heater, leading to leaks or faults.

Hard water, in particular, can be especially damaging. Hard water contains high amounts of minerals such as calcium and magnesium that can stick to the interior of your unit, forming limescale and other blockages.

To prevent these issues, homeowners can install a water softener. Water softeners are designed to remove hard minerals from water, reducing the risk of buildup inside your tankless water heater.
