    I have a Buderus Logalux S-120 water heater with a new Aluminum/Zinc replaced anode.

    I have well water that is softened and am getting the “rotten egg” smell at all hot water outlets, even though plumber replaced the old rod with the Alumnium/Zinc rod.

    I have two questions:

    1) Will the smelly water problem go away or even lesson if I replace the Aluminum/Zinc anode with a powered anode?

    2) I’d like to purchase a new anode from this sight, given the model of my heater, which anode would be appropriate?

    Thanks for your help!

    First off, yes, a powered anode will solve the odor issue. But the trouble is that you have a Buderus. It may not be possible to find a powered anode that will work with it. The user guide appears to show a hex anode, but the thread size may be wrong because Buderus is a European design and the anodes are not the same as American ones. If it’s compatible, though, you’d want a Corro-Protec, SKU23. Check with Buderus to see if the thread size is compatible but don’t tell them you’re considering a powered anode. That might void the warranty. And that’s not because there is anything wrong with powered anodes. Manufacturers only warranty products they’ve tested, which is actually sensible.
