For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%-34% more energy efficient than conventional storage tank water heaters. For larger use of hot water, approximately 86 gallons per day, they can be 8%-14% more energy efficient. In addition, by installing a tankless hot water heater at each hot water outlet, you can save 27%-50% of energy.
