What is a Tankless (or On-Demand) Water Heater?

Traditional water heaters are large tanks connected to a burner or electrical heating element. The tank fills with heated water and distributes it to the piping when turned on. This water heater is ubiquitous in homes across DE, MD, PA, and around the globe. They aren’t particularly energy-inefficient. The heated water in the tank must be reheated periodically to maintain the proper temperature, even when the water is not being used. This wastes electricity or gas.

Tankless water heaters, also known as demand-type or instantaneous water heaters, provide only hot water as needed. They don’t produce the standby energy losses associated with storage water heaters, which can save you money. Here you’ll find basic information about how they work, whether a tankless water heater might be right for your home, and what criteria to use when selecting the suitable model.

Tankless water heaters, on the other hand, have no storage tank. They are “on-demand” systems, heating water only when the homeowner needs it. Without a bulky storage tank, they can be installed in tight spaces, helping to save room inside the home.

What are the Advantages and Disadvantages of a Tankless Water Heater?

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. They can be 8%–14% more energy efficient for homes that use a lot of hot water — around 86 gallons per day. You can achieve even greater energy savings of 27%–50% if you install a demand water heater at each hot water outlet. ENERGY STAR® estimates that a typical family can save $100 or more yearly with an ENERGY STAR-qualified tankless water heater.

The initial cost of a tankless water heater is greater than that of a conventional storage water heater. Still, tankless water heaters will typically last longer and have lower operating and energy costs, which could offset their higher purchase price. Most tankless water heaters have a life expectancy of more than 20 years. They also have easily replaceable parts that extend their life by many more years. In contrast, storage water heaters last 10–15 years.

Tankless water heaters can 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 constantly burning pilot light. This can sometimes offset the elimination of standby energy losses 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. Ask the manufacturer how much gas the pilot light uses for the model you’re considering. If you purchase a model that uses a standing pilot light, you can always turn it off when it’s not in use to save energy. Also, consider models with an intermittent ignition device (IID) instead of a standing pilot light. This device resembles the spark ignition on some gas kitchen ranges and ovens.
