FAQs About Tankless Water Heaters: Answers to Common Questions

Posted April 15, 2014

Tankless water heaters, also known as on-demand water heaters, are becoming increasingly popular for their efficiency and convenience. 

If you’re considering installing one, you may have questions about how they work, their advantages, and the installation process. Here, we answer some of the most frequently asked questions about tankless water heaters.

How Does a Tankless Water Heater Work?

A tankless water heater works on demand, meaning it doesn’t use gas or electricity until hot water is needed. When you turn on a faucet or shower, the unit activates and heats water as it flows through the system. Unlike traditional water heaters, it doesn’t store hot water in a tank.

Premium tankless water heaters, also called hybrid water heaters, include a buffer tank with a pump. This eliminates the "cold water sandwich" effect—a brief burst of cold water before hot water reaches the faucet—and allows hot water to flow more quickly to the point of use.

What Are the Advantages of Using a Tankless Water Heater?

Tankless water heaters offer several benefits:

  • Endless hot water: You can enjoy consistent hot water for as long as you need, whether it’s a quick shower or hours of use.
  • Energy efficiency: They are more efficient than traditional water heaters, reducing your gas or electricity bills.
  • Longevity: All parts are replaceable, which means a much longer lifespan compared to tank-type water heaters.
  • Space-saving design: Without a bulky tank, tankless water heaters save floor space and won’t flood your home if they fail.
  • Better warranties: They often come with longer warranties compared to traditional models.

Can a Tankless Water Heater Be Installed in the Same Place as the Old Water Heater?

Yes, tankless water heaters are highly versatile and can be installed almost anywhere, including the same location as your old water heater. The installation process allows flexibility, and adjustments can be made to fit the space available in your home.
