How Water Heaters Lose Efficiency as they Age

Last updated 5 years ago

Your hot water heater is one the largest, most energy intensive appliances in your home. While many newer water heaters can keep wasted energy to a minimum, older models may dramatically inflate your water heating costs. Here’s a look at the different reasons why water heaters lose efficiency as they get older:

1.  Buildup of Sediment and Scale

When water is warmed in your water heater, the minerals dissolved in your tap water solidify and collect inside of the tank. In addition to potentially damaging your water heater, sediment buildup can shrink the available volume in the tank. This means that your water heater has to use more energy to produce the same amount of hot water, which means higher energy costs.

2.  Wear of the Burner and Heating Element

Your burner or heating element can experience wear and tear over time. Rust, fuel deposits, sedimentation, and other changes in the health of your burner or heating element can make your water heater much less energy efficient. While proper maintenance and professional repair will help to maintain efficiency levels, the heating components will eventually wear out and fail.

3.  Damage to the Water Tank

As your water heater’s tank ages, it may develop problems that reduce its energy efficiency. Factors like rust buildup, sediment deposits, and leaking can affect how much hot water you get for every dollar you spend on energy. Water heater tank damage is usually difficult or impossible to repair, making replacement your most practical option.
