Sacrificial anodes for water heaters are installed in order to protect the water heater against corrosion. The purpose of the anode is to "sacrifice" itself and thereby protect the water heater against corrosion. That way, you never have to replace the water heater because it has rusted, but only the anode. Sacrificial anodes for water heaters are something we have many of!
