A demand-type water heater—also known as a “tankless water heater”—is an advanced water heater with several benefits for your home: chiefly, that unlike a standard water heater, it cannot “run out” of hot water. In addition to their energy-efficient and compact design, this versatility has made them popular for large families where multiple people need to shower in the morning or evening.
Overall, there are many benefits to making the switch to a demand-type water heater. In this article, we’re going to run through some of the advantages of upgrading.

How a demand-type water heater works
First-things-first: as the name implies, tankless water heaters do not have tanks. Traditional (or “standard”, “storage-type”) water heaters warm water inside of a tank, and then store that water until needed at the faucet when showering, doing dishes, or laundry. In contrast, demand-type water heaters heat water as needed, running cold water past heated coils or gas burners inside the unit to quickly heat it and deliver it to your faucet.
Because they don’t need a tank, demand-type water heaters are often more compact. Many units can actually be wall-mounted in your garage.
Many homeowners like the convenience of an endless supply of hot water, but tankless units are also more energy-efficient than traditional storage-type models. Storage-type systems work constantly to keep water hot, whether it’s needed or not. Demand-type units only use energy when required.
According to the U.S. Department of Energy, an electric tankless unit can save about $44 per year on energy costs compared to a conventional storage water heater. Gas heaters can save about twice that, reducing costs by an average of $108 annually.
Consider your home’s hot water needs
One of the drawbacks of demand-type systems is that there are limits on how much hot water they can provide at any given time. A single unit may not be able to keep up with a dishwasher and shower running simultaneously.
However, if your home does have high demand, the compact size of tankless models makes it possible to install a unit near each hot water outlet. ENERGY STAR estimates that doing so can save between 27 and 50 percent in energy costs compared to a single storage-type heater.
Tankless water heaters are more expensive than systems that use tanks, but they also have a longer life expectancy and easily replaceable parts. While storage heaters usually last between 10 and 15 years, most demand-type models have a lifespan of more than 20 years.
