How long do storage tank combustion water heaters typically last?

5 to 7 years
8 to 10 years
10 to 12 years
15 to 20 years

The correct answer is: 10 to 12 years

Storage tank combustion water heaters typically have a lifespan of around 10 to 12 years. This timeframe is influenced by several factors, including the quality of the unit, the frequency of use, water quality, and maintenance practices. Regular maintenance, such as flushing the tank to remove sediment buildup, can help extend the life of the heater. While other ranges of years mentioned may apply to specific models or other types of water heaters—like tankless water heaters or high-efficiency models—the average life expectancy for a traditional storage tank water heater falls within the 10 to 12-year mark. It’s essential for homeowners to be aware of this timeframe to plan for potential replacements and to ensure they get the most efficient performance out of their units during that period.
