The lifespan of a conventional water heater typically ranges from 8 to 12 years, depending on usage, maintenance, and water quality. However, with diligent upkeep, this lifespan can often be extended. Tankless water heaters, on the other hand, generally have a longer lifespan of over 20 years due to their design and fewer moving parts. Regular maintenance and timely repairs play significant roles in how long a water heater remains efficient and reliable. At Powers Plumbing, we provide full-service maintenance plans designed to maximize the longevity and performance of your water heater in the distinct San Diego environment.
