Whether you’re moving into a new house or it’s time to replace your old water heater, knowing the differences, pros and cons of tank and tankless water heaters will help you make the best decision.

  • Minimal upfront cost
  • A reliable system that has been perfected over time
  • Quick and easy installation
  • Readily available back up water supply in the event of an emergency
  • Electric tank water heaters don’t always require major changes to the design of your home when they are installed

The cons of tanks water heaters are:

  • Shorter lifespan (usually 10-15 years)

  • Wait time once the tank is emptied and has to refill
  • Increased risk of property damage caused by leaks

If you find yourself on a budget or need a unit installed quickly, a tank water heater might be your best option.

Tankless Water Heaters

Tankless water heaters are compact devices that heat your water on command using either gas or electricity. Because tankless water heaters have output limits, you’ll need to be cognizant of how much water you use at one time. A common problem for larger families is running out of hot water when everyone is trying to shower at the same time in the morning. With that being said, tankless heaters that run on gas generally have higher output limits than ones that are powered by electricity.

  • Money, energy and water saved since the machine isn’t running until you turn it on

  • More expensive installation and setup costs
  • Significant adaptations may have to be made to your home
  • The upfront costs may be greater than the money you save over the long term depending on the circumstances

If you already have gas in your house and the cost of installation poses no issue, installing a tankless water heater can save you substantial money on your heating and electric bills every month.
