Do tankless water heaters require more electricity?
According to Energy.gov, “For homes that use 41 gallons or less of hot water daily, demand (or tankless) water heaters can be 24% to 34% more energy efficient than conventional storage tank water heaters.” Tankless water heaters (if gas-fired) will save homeowners over $100 annually the longer they remain in service.
Is it worth it to install a tankless water heater?
According to the U.S. Dept. of Energy, a tankless water heater is more efficient and uses less energy than a conventional water heater, providing a $25 to $107 in annual savings. If your hot water use is low (less than 41 gallons per day), a tankless water heater will be 24% to 34% more efficient.

What is a tankless water heater?
Natural gas tankless water heaters have electronic ignition and power-vented exhaust. They are usually installed close to where hot water is needed. Depending on your hot water use, a tankless water heater may not have enough capacity to meet your home’s needs.
What is a storage tank water heater?
Water is heated and stored in a tank so that it is available to use in the home at any time. When a storage water heater is not in use it loses heat through the shell of the tank. New natural gas storage tank water heaters have increased insulation levels to help minimize the heat loss.
What is an on-demand water heater?
Instead of using a tank to store hot water, these heaters, also known as on-demand or instantaneous water heaters, only heat water when it is needed and avoid heat loss through the tank walls and water pipes.
