How often should hot water heaters be flushed to maintain efficiency?

Flushing a hot water heater at least once a year is important for maintaining its efficiency and prolonging its lifespan. Over time, sediment and mineral buildup, such as calcium and lime, can accumulate at the bottom of the tank. This accumulation can lead to reduced efficiency, as the heating element has to work harder to heat the water, resulting in higher energy bills and potentially damaging the heater.

By flushing the tank annually, the accumulated sediment is removed, allowing for efficient heating and helping to prevent corrosion and other issues that could arise from prolonged sediment buildup. This routine maintenance not only enhances the efficiency of the water heater but also helps in reducing energy consumption and extending the overall life of the appliance, making it a recommended practice for homeowners.
