Reducing the Impact of Water Softeners on Heaters

There are other elements in water besides H₂O, such as calcium and magnesium. The concentration of these minerals depends on geographical location and the water source (municipality or a private well). A high concentration of these minerals is what commonly creates the condition know as “hard water”.

Hard water can be a nuisance, clogging or corroding pipes and fixtures, thus ultimately impacting the comfort of your shower or bath.

The installation of a water softener is a common solution to this issue.

How a Water Softener Works - A softener replaces the calcium and magnesium ions with sodium ions.

The Problem -The exchange of calcium and magnesium ions for sodium ions, results in the water being more conductive. The higher conductivity of the water will cause the water heater’s anode rod to deplete more rapidly. Once the anode rod is depleted, the tank is more susceptible to corrosion.

Solution-Bradford White’s operation manuals recommend the inspection of anode rods every two years. If using a water softener it is important to inspect the anode rod more frequently, and to replace it if necessary.

The anode rod is a crucial part to ensure the longevity of a water heater.
