What Factors Affect the Lifespan of A Water Heater?

The local water quality is one of the factors that contribute most significantly to the performance and longevity of water heaters. Specifically, highly alkaline water will lead to the accumulation of scale, which will impact the efficiency of tankless and gas storage water heaters and can lead to decreased water hater life. Conversely, soft water increases the risk of corrosion, which can decrease equipment life by more than half if not properly mitigated. Increasing the lifetime of water heaters can improve the cost-effectiveness and increase the amount of savings achieved by an efficient water heater investment. Based on the specific water quality characteristics in a given location, different water heater design parameters and maintenance requirements can be applied to mitigate scale accumulation and corrosion in hard and soft waters, respectively.
 
Like most appliances, a regular maintenance schedule is also very important for extending the lifespan of water heaters. Replace the anode rod in time, keep the lining of the tank from corroding, maintain the temperature of the water in its tank continuously, they will attribute to increasing the service life of a water heater.
