One or the other, not both.
A water heater with a tank heats the water to a given temperature and only fires the propane (or electric heater or both) when the temperature in the tank reaches a lower threshold. This can be due to ambient heat losses or the intrusion of cold water as the hot water exits the tank to the faucets and/or shower.
An "On Demand" or tankless water heater only fires the propane when there is enough water flow sensed through the heating coils in the tank; heating the water as it flows through the heat exchanger.
So which one do you have again?
