Tankless vs. traditional water heaters

Understanding the difference between tankless water heaters and traditional storage models

When it comes to replacing your water heater, understanding all the options available is important. Water heating is the second highest energy user in the average home, and once installed, you likely won't need another one for another decade or so. Here, we break down the difference between modern tankless water heaters and more traditional, or storage, water heater models. 
 

Understanding the difference

Tankless Storage 
  • Tankless models heat water on-demand, meaning you'll enjoy an endless supply of hot water without the need for a tank.
  • Storage water heaters are the most common model in the U.S. 
  • According to the EIA, tankless water heaters are 24-34% more energy efficient than conventional storage tank water heaters, because you only heat the amount of water you really need. (Source)
  • If you're watching your budget closely, traditional water heaters offer lower upfront costs between installation and purchase price. 
  • The small size of the tankless water heater makes it easier to fit in smaller spaces, like apartments, finished basements or even outside your home. 
  • Storage water heaters offer a steady reserve of hot water and are an economical way to heat water for all your household needs.
