Pros and Cons of Tankless Water Heaters


Tankless water heaters have been popular in the EU for a while and are becoming more and more popular among Canadian homeowners–and for good reason. They’re highly energy efficient and although they’re more expensive than their tank counterparts, you’ll reap the benefits of energy savings that will add up over time. 

If you’re in the market for a new hot water heater, or if you’ve been wondering if making the change to tankless will provide benefits that’ll make it worth the investment, consider tankless water heaters. Take a look at the pros and cons of tankless water heaters before deciding on your new water heater installation in Mississauga, ON.

The Pros of Tankless Water Heaters

  • Constant Hot Water: The idea of never running out of hot water halfway through a shower could be reason enough for some homeowners to make the switch. Because tankless water heaters heat water on demand, you’re unlikely to run out of water when you need it. 
  • Longevity: They last longer than tank water heaters which means you won’t have to worry about replacing it for 15-20 years. Compare this to tank water heaters that only have a lifespan of 10-15 years. 
  • Compact Design: Their compact design takes up much less space than a tank heater. They can even be mounted on the wall. That means more room in your garage or man cave.
  • Cleaner Water: As tank water heaters age, they can develop deposits of rust, scale, and grime on the inner walls which can contaminate your water. Tankless heaters provide clean, pure water for their lifespan.
  • Decreased Energy Bills: Because they’re not heating water 24/7, they use a lot less energy. That energy saving translates into cheaper energy bills for you.

The Cons of Tankless Water Heaters

  • Higher Initial Purchase Price: Even though they’re smaller, tankless water heaters cost more than their traditional tank counterparts. That’s because they’re more complex and technologically advanced. 
  • Hot Water Delay: Because tankless water heaters only heat water on demand, there will be a slight delay between the time you turn on the hot water and actually get hot water flowing from the faucet, tap, or showerhead. However, this delay is only 10-15 seconds.
  • Cold Water Sandwich: This occurs when cold water is “sandwiched” in between hot water usage. The intermittent use of hot water causes you to feel an initial surge of hot water, followed by cold water, which quickly turns hot again.

Is Tankless Right for You?

Perhaps you’ve decided that the pros outweigh the cons and you’re ready to make the switch to tankless. While tankless water heaters are incredible systems, they’re not necessarily the ideal option for your particular household. If you buy one that’s improperly sized, it won’t be able to provide enough hot water for your entire family. 

Every household is different. Hopefully, we’ve given you some food for thought so you can evaluate your family’s needs and decide if now’s the time to switch to tankless technology.
