We had our motor home built for us. It came with the standard HW tank but we had the option of ordering the hot water on demand system. We have enjoyed it as it puts out a continuous flow of hot water. However for it to work well you have to have close to 55 pounds pressure for it to operate properly. If you are in a campground with low pressure we fill our fresh water tank and run the pump. We find that it uses very little propane as it only heats when you draw hot water. The only draw back is it is a little more difficult traveling in very cold winter weather. It is important that you drain it when traveling in freezing weather as it causes major damage if your copper coils burst. You are fine if you are set up in even zero degree weather. We have used it at six degrees. You cannot travel with the gas on to the unit as when it runs while moving the flame can fan out and burn its wiring.
My new one will keep the temps high enough to keep the unit from freezing. Haven't had it blow out yet. my fridge has never blown out either
