They will waste more water, unless they have a constant recirculation or heat setting. This setting keeps the heater warm and reduces the amount of time for the heater to start heating the water. Kind of defeats the purpose of the unit. All the tankless heaters take time to sense the water flow, start the ignition cycle and then get the heat exchanger up to temp. could be anywhere from 5 seconds to 20 seconds.
