How Long Should Your Tankless Water Heater Last For?

One of the most common questions asked by consumers about tankless water heaters is how long they will last. A tankless water heater can last anywhere from 15 to 20 years with proper maintenance and operation. In comparison, a standard tank water heater normally has a working life of 10 years or less.

How Do Tankless Water Heaters Work?

Tankless models heat water only as you need it. When you turn on a hot water tap, it will trigger the water flow through the tankless unit. This will cause the heating elements to turn on, rapidly heating the water. Within a very short time, the water coming out of your tap will be hot. In comparison, a tank water heater stores gallons of heated water in anticipation of hot water use. The continual heating and reheating of water is not energy efficient and can drive up your energy costs.

Why Do Tankless Water Heaters Have a Longer Lifespan?

The biggest point of failure within a regular water heater is the tank itself. During the heating process, minerals in the water separate, floating down into the bottom of your tank and clinging to heating elements. This causes sediment buildup, which can lead to a failure in the tank body. Once the tank ruptures, the entire water heater needs to be replaced.

A tankless heater still contends with the corrosion caused by water. However, it doesn’t run the risk of a tank failure. With routine maintenance, a tankless model can last up to twice as long as a standard tank water heater.
