I know I could just trip the breaker but would like it to be in the control panel. I have open switch slots that just have the covers over them because they are unused.
It's a hair more complicated than just dropping a switch. First off, the electric heating element is 120 volt AC, not 12 volt DC (like most of the switches in the control panel).
You would have to get a switch and wire rated for 120 volt AC, to be able to do it just from a switch/wire standpoint.
Suburban does have an option for what you are trying to accomplish, but it utilizes a 12 volt DC switch/wire going to a 12vDC/120vAC relay, where the relay then turns on the 120 volt heating element.
What many people do instead, is to make a switch for the 120 volt AC outlet, that the water heater is plugged into. They then can just switch on/off the outlet..... and this turns the water heater element on/off.
Hold on and I will get you some links and schematics.
