That will wait until spring though.
Several members have just made ways to switch the electrical outlet that the water heater is plugged into on/off. They leave the outside switch in the on position, and just use their modified outlet switch to turn the electrical on/off at the outlet itself.
Others still, leave the outside switch in the on position, and just use the electrical breaker (in the breaker box) that powers the outlet to the water heater as an on/off switch.
Others, even add a switch inline between the breaker box and the water heater outlet.
There are several forums detailing this. Here is one from Iggy:
Added switch for Hot Water Heater inside
Just keep in mind, when making a switch for the 120 volt electrical element, the switch itself and any added wiring has to be rated for 120 volt AC (and usually 15 amps).....and not 12 volt DC (like the propane/DSI switch is).
