Scubawise,
Don't know what unit you have but if you have PEX piping a air blow is quite sufficient but it does require a careful understanding approach.
If you have an older unit with Non-PEX pipe best to air Blow then use the non-toxic RV antifreeze to be on the safe-side.
If you have the on-demand water heater like I do don't take a chance. Use the RV antifreeze.
