The lifespan of water heaters in Colorado is influenced by factors like water quality, maintenance, and usage. On average, traditional tank water heaters typically last 10-15 years, while tankless models may endure 20 years or more. In areas with hard water, like some parts of Colorado, regular maintenance is crucial to extend longevity. Flushing the tank annually and addressing sediment buildup can help optimize performance and prolong the water heater's lifespan.
