Choosing Between Tankless and Conventional Water Heaters

When it comes to selecting a water heater for your home, the decision can be overwhelming. With so many options available, how do you know which one is right for you?

In this ultimate guide, we will discuss the main differences between tankless and conventional water heaters, as well as the advantages and disadvantages of each. By the end of this article, you will have all the information you need to make an informed decision about which type of water heater is best suited for your needs.

Tankless Water Heaters: How Do They Work?

Tankless water heaters, also known as on-demand or instantaneous water heaters, heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe and into the unit.

A gas burner or an electric element heats the water, providing a constant supply of hot water as needed. This eliminates the need to wait for a storage tank to fill up with enough hot water.

Advantages of Tankless Water Heaters

  • Energy Efficiency: According to the U.S. Department of Energy, tankless water heaters can be 24% to 34% more energy efficient than conventional storage tank water heaters for homes that use 41 gallons or less of hot water daily.
  • Longevity: Tankless water heaters typically have a longer life expectancy, lasting up to 20 years or more, compared to 10-15 years for conventional water heaters.
  • Space Saving: Due to their compact size, tankless water heaters can be installed in smaller spaces, freeing up valuable square footage in your home.

Disadvantages of Tankless Water Heaters

  • Higher Initial Cost: Tankless water heaters generally have a higher upfront cost compared to conventional water heaters, although they can save money in the long run through energy efficiency.
  • Limited Flow Rate: Tankless water heaters can struggle to supply enough hot water for simultaneous, multiple uses in larger households.

Conventional Water Heaters: How Do They Work?

Conventional water heaters, also known as storage tank water heaters, store and heat a large amount of water (usually 30-50 gallons) in a tank. The hot water is released from the top of the tank when a tap is turned on, and cold water enters the bottom of the tank to replace it. The heating element within the tank maintains the water temperature, ensuring a consistent supply of hot water.

Advantages of Conventional Water Heaters

  • Lower Initial Cost: Conventional water heaters typically have a lower upfront cost compared to tankless water heaters.
  • Easy to Replace: If a conventional water heater fails, it can be easily replaced with a similar unit, often without the need for additional plumbing or electrical work.

Disadvantages of Conventional Water Heaters

  • Lower Energy Efficiency: Conventional water heaters are generally less energy efficient than tankless water heaters, as they continuously heat the water in the tank, even when it's not being used.
  • Shorter Lifespan: Conventional water heaters have a shorter life expectancy, typically lasting 10-15 years.
  • Space Requirements: Due to their large size, conventional water heaters require more space for installation, potentially taking up valuable square footage in your home.
