Breaker switch for hot water heater?

Not sure what unit you have, but for mine, in addition from the wall switch, there is a rocker switch under the heater exterior cover that can be operated to isolate the electric heater. You can also isolate further by opening the AC breaker for the heater in the power panel. Operating the gas switch inside will shut down the gas side, and you can also pull the 12VDC fuse for the water heater in the distribution panel for extra isolation. You can also turn off the gas at the bottles.... how sure do you want to be?

One can also install a battery disconnect switch that will ensure the heat will not be available.
