Should I be emptying my hot water heater?

My system must be different, I don't heat hot water. I only heat the cold water.

Really? What happens when you don't use any hot water for a while and the water in the tank falls below the low temperature set point? Do you drain all the hot water out and replace it so you only heat cold water?

Really?

Does this mean I'm never going to find out how you only heat cold water?
That's a shame cause I was also going to ask if you had propane tanks on your RV.
Cause I got both, a hot water heater and propane tanks.
