Factors that Can Affect Your Water Heater’s Efficiency

corroded water heater Temecula, CA

You need your water heater to function at its best year-round, especially during the colder months. If you’re noticing a decline in your appliance’s efficiency, several factors may be to blame. As your go-to team for water heater repair in Temecula, CA, A.M. Plumbing & Rooter outlines what can cause your water heater to suffer reduced performance.


A traditional hot water heater has an anode rod. This sacrificial anode is usually made of magnesium or aluminum and is meant to attract the corrosive elements in the water so they will not cause damage to the tank. After a significant amount of time, sacrificial anodes can completely corrode and lose their ability to perform their duties. When this occurs, the tank becomes vulnerable to rust and can begin to leak, causing both efficiency and safety issues.

Sediment Buildup

Minerals and other debris can accumulate at the bottom of the tank, forming a thick sediment layer. This significantly reduces the water heater’s efficiency by acting as an insulator, ultimately preventing the heat from transferring properly to your water. This results in your unit working harder and longer than necessary to produce the hot water you need and driving up your energy bills.

During water heater installation, your plumber will provide instructions on how to drain and flush your tank regularly to prevent sediment buildup. In areas with hard water, installing a water softener may also be beneficial to reduce the amount of minerals in your water.

Age of the Water Heater

A traditional tank-style model has an average lifespan of 8 to 12 years. In comparison, a tankless water heater lasts about 20 years. But this depends on usage and maintenance, of course. No matter which type you own, its efficiency will naturally decline as it ages. If your water heater is reaching its expected service life, it may be time to consider a replacement for better performance.

Your water heater is one of your home’s most used and essential appliances. Make sure it runs at peak efficiency by getting top-notch water heater services from A.M. Plumbing & Rooter. We are dedicated to providing the reliable solutions you need.
