Which Size Should You Choose For Your Anode?

Published and updated

Our response

The size of your anode depends on your anode type and the capacity of your water heater. In the case of a sacrificial anode, its rod is much larger than an impressed current anode, because the more material there is, the longer it offers a protection time.For the Corro- Protec impressed current anode, its protection is provided by an electrical current that is proportional to the capacity in gallons of your water heater and not to the size of its rod.
