1. TRUE Tankless RV water heaters CANNOT utilize 120 volts to give continuous HOT water. Even HOME 240 volt systems must be designed for AC operation and will NOT function as well as LP or Natural Gas Tankless Water Heaters.
2. Even the LARGE Aqua hot with 2- 120 elements, will only give about 4 gallons of hot water before the 120 elements cannot keep up with the demand--Aqua hot states to utilize the Diesel burner for continous
3. Most RV TANKLESS water Heaters are LP powered or Diesel powered(Aqua Hot)
4. Lets say the OP came back after a week and had Hot water. He needs to then run the Hot water and see HOW long/much hot water he had. I doubt more than a gallon if his switches were indeed turned off. But, if he does have a 120 system also, then that would account for the hot water he had but just not much hot water. Doug
I'll try that tomorrow, good idea. At least, then I would know what the source is. As you stated the electric is only for things like washing your hands, doing a small load of dishes, etc. I you are going to take a shower, you have to use the LP.
