Advantages of Tankless Water Heaters

Also called on-demand heaters, tankless units don’t store hot water – they quickly heat it as needed. This design offers several benefits to homeowners, including:

  • Unlimited supply of hot water – Everyone in the household could take hour-long, back-to-back hot showers, and the supply still won’t run out.
  • Reduced energy consumption – Because tankless models heat water on demand rather than continually, they’re much more efficient than traditional tank heaters.
  • Smaller appliance size – Instead of taking up a large amount of floor space, a tankless model can be mounted on small section of the wall.
  • Longer warranty – On-demand heaters typically come with a 12 to 15 year warranty, while traditional tank models are generally covered for a shorter period of time.


Drawbacks of Tankless Water Heaters

When it comes to water heater replacement, going tankless isn’t all gravy. The disadvantages of installing a tankless model include:

  • Higher upfront cost – On-demand heaters are more expensive than traditional tank units, and the difficulty in installation further drives up the price.
  • Increased time to deliver hot water – Because tankless models heat water as it passes through, household members may be left waiting for longer.
  • Flow limitation – In colder climates, small on-demand heaters may provide a lower flow of hot water
  • Need for regular flushing – Scale and mineral buildup can make tankless models malfunction, so units must be flushed regularly to prevent an early demise.


Should You Go Tankless?

As you can see, making a decision on whether to install a traditional tank or tankless water heater requires careful consideration.

If you opt for a tankless model, you’ll pay more for water heater replacement. But, you’ll also enjoy significant energy savings every month – and with proper maintenance, the unit can remain in good working order for decades.


In contrast, a tank heater is likely to need replacement within 10 to 15 years. However, the cheaper upfront cost may outweigh the benefits of going tankless.
