Again, though, if you drain the hot water it must remain shut off! So at least shut the switch off If you do the heat and dump into the main tank thing Phil described. Since I typically camp with others, I’d pull the fuse or figure out some other way to prevent someone switching the tank on if I was camping with a drained hot water tank.
I wish they would have located the hot water tank switch inside the cabinet.
A fuse!
Damn I forgot about that when I drained the system while skiing this last winter.....dummy just used duct tape to keep toggle on 'off'.
