When you winterize the water system you are replacing water with potable antifreeze. The Aquahot heats its own antifreeze solution that transfers heat to the heat exchangers, the hot water tank (and the engine if you turn that switch on). When you drive the engine heats the same fluid. So once winterized running the Aquahot on diesel or electric to heat the coach or the engine works fine. The electric heating element in the Aquahot will provide enough heat down to about 40°, maybe a bit less. At that point it can't keep up with the heat demand and the fans in the heat exchangers and the Aquahot pumps will run almost continuously. Not good for the batteries.
We leave the diesel Aquahot on all day. Once the system is heated up it only needs to keep it hot by running every once in a while. It will use some battery but not too much. We turn the heat down but not off at night or if we are not in the coach. You should be OK overnight running the Aquahot. We get by in the late Fall with a couple hours of generator time. Be warm.
