Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which can save money.
Check out the Energy Saver 101: Water Heating infographic to learn if a tankless water heater is right for you, and our #AskEnergySaver discussion on water heating for more answers on efficient water heating.

Tankless water heaters heat water instantaneously without the use of a storage tank. When a hot water faucet is turned on, cold water flows through a heat exchanger in the unit, and either a natural gas burner or an electric element heats the water.
As a result, tankless water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water. However, a tankless water heater's output limits the flow rate.
Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a tankless water heater to its limit.
To overcome this problem, you can install two or more tankless water heaters. You can also install separate tankless water heaters for appliances -- such as a clothes washer or dishwater -- that use a lot of hot water in your home. However, additional water heaters will cost more and may not be worth the additional cost.
Tankless water heaters avoid the standby heat losses associated with storage water heaters. However, although gas-fired tankless water heaters tend to have higher flow rates than electric ones, they can waste energy if they have a pilot light. This can sometimes offset the elimination of standby energy losses when compared to a storage water heater. In a gas-fired storage water heater, the pilot light heats the water in the tank so the energy isn't wasted.
The cost of operating a pilot light in a tankless water heater varies from model to model. Review the manufacturer's literature to determine how much gas the pilot light uses for the model you're considering. Look for models that have an intermittent ignition device (IID) instead of a standing pilot light. This device resembles the spark ignition device on some natural gas furnaces and kitchen ranges and ovens.
Proper installation depends on many factors. These factors include fuel type, climate, local building code requirements, and safety issues, especially concerning the combustion of gas-fired water heaters. Therefore, it's best to have a qualified plumbing and heating contractor install your demand water heater. Do the following when selecting a contractor:
If you're determined to install your water heater yourself, first consult the manufacturer. Manufacturers usually have the necessary installation and instruction manuals. Also, contact your city or town for information about obtaining a permit, if necessary, and about local water heater installation codes.
After your demand water heater is properly installed and maintained, try some additional energy-saving options to help lower your water heating bills. Some energy-saving devices and systems are more cost-effective to install with the water heater.
Energy efficiency is the use of less energy to perform the same task or produce the same result. Energy-efficient homes and buildings use less energy to heat, cool, and run appliances and electronics, and energy-efficient manufacturing facilities use less energy to produce goods.
Energy efficiency is one of the easiest and most cost-effective ways to combat climate change, reduce energy costs for consumers, and improve the competitiveness of U.S. businesses. Energy efficiency is also a vital component in achieving net-zero emissions of carbon dioxide through decarbonization.
The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) champions clean energy through its technical offices and programs that fund research and development and promote energy efficiency across all sectors of the U.S. economy. Learn how you, too, can become a Clean Energy Champion.
Energy-efficiency programs improve community resilience and address energy equity by bringing efficient, cost-effective technologies and infrastructure to underserved communities, including communities of color.
Reducing energy use is essential in the fight against climate change, because traditional power plants burn fossil fuels that release greenhouse gases and contribute to air pollution. Energy-efficient homes and buildings are also better equipped to switch to renewable energy, which does not produce harmful emissions.
Energy-efficiency improvements reduce the amount of electricity on the grid at one time, known as load, minimizing congestion and stress on the U.S. electric grid. Less load prevents power disruptions.
The Building Technologies Office works to enable high-performing, energy-efficient and demand-flexible residential and commercial buildings, in support of an equitable transition to a decarbonized energy system by 2050, starting with a decarbonized power sector by 2035.
Buildings and manufacturing plants account for about two-thirds of carbon dioxide emissions in the United States. Energy not used is energy saved, and the U.S. Department of Energy encourages partners to lead with energy efficiency. Organizations can set goals and partner with the Energy Department to reduce greenhouse gas emissions through the Better Climate Challenge.
The Industrial Efficiency and Decarbonization Office's industrial decarbonization efforts are aimed at phasing out atmospheric greenhouse gas emissions from all aspects of industry, in support of the Biden-Harris administration's plan to achieve net-zero carbon emissions by 2050.
EERE is dedicated to building a clean energy economy, which means millions of new jobs in energy efficiency, including construction, manufacturing, and more across industries. Learn more about job opportunities in clean energy:
