What is an Anode Rod?

Water heaters should be maintained regularly in order to keep them running effectively and efficiently to keep your energy bill down. Regular service can also help stretch your water heater's lifespan. Normally, we recommend water heaters be serviced once a year, especially if your water heater sees a lot of use.


One of the most important parts of maintenance is checking and replacing the anode rod in your water heater. The anode rod is a metal rod that runs down the center of your tank, usually made from magnesium, aluminum, or aluminum/zinc alloy. This is one of the most vital components of your water heater. Its purpose is to attract the sediment and corrosive elements (like minerals in the water) so that they corrode the anode rod rather than the inside of your water heater tank.

Because of the mineral content in the Las Vegas water supply, it is important to get your anode rod replaced more often than in other parts of the country. Make sure to get your replaced on a regular basis to ensure that your water heater is running efficiently and effectively. We recommend getting it checked annually or biannually.


On average, water heaters use about 13-15% of household energy, but when the heater malfunctions, it may have to work twice as hard to give you the same amount of hot water. This can lead to an increase in your energy costs, and might seriously impact your household expenses.
