Until fairly recently, the only type of water heater used in homes was the tank variety. Tank water heaters make use of large storage tanks, which keep many gallons of water heated at all times just in case they are needed. In the past few years, however, tankless water heaters have started to become more and more popular. If you are in the market for a new water heater, take a look at what a tankless water heater can do for you.
How Tankless Water Heaters Work
A tankless water heater, as you might imagine, doesn’t use any kind of storage tank to keep water heated. Instead, it makes use of a heat exchanger, not unlike those that boilers use to heat water. As water flows through the heat exchanger, it absorbs heat from the burner assembly below on the way to its destination. A tankless water heater turns on only when it is needed, and turns off again as soon as the demand for hot water subsides. This is in contrast to storage tank water heaters, which tend to stay on at all times to maintain a supply of hot water.
Advantages of Tankless Water Heaters
By turning on only when needed, a tankless water heater can save you a sizeable amount of money in operating costs on a yearly basis. Not only that, but not needing a storage tank makes the entire system a good bit smaller than a tank water heater. Tankless water heaters are designed to provide the same output levels as tank water heaters, without the added drawbacks of size constraints and energy inefficiency. If you want to cut down on costs while still having access to the same amount of hot water, a tankless water heater is a good idea.
