The answer to the lifespan of a water heater is that the average lifespan is 8-12 years, with proper maintenance and care. Water heaters are a critical appliance in most homes, providing hot water for daily use. However, they are subject to wear and tear over time, and their lifespan can be affected by factors such as the quality of the unit, the water quality in your area, and how often the water heater is used.
With proper maintenance, such as flushing the tank annually to remove sediment buildup and checking the anode rod every few years, a water heater can often exceed the average lifespan. However, even with good maintenance, water heaters will eventually need to be replaced as components wear out over time. When a water heater starts to show signs of age, such as decreased efficiency, strange noises, or leaks, it's a good idea to start planning for a replacement to avoid the risk of a sudden failure and potential water damage.
