If your home needs a new water heater, you’ll find that water heaters come in two different types: traditional and tankless. On the surface, it may seem like an inconsequential decision, but a water heater can impact your life more than you may think. Just think about the annoying feeling that occurs when you’re in the middle of taking a shower only for the hot water to run out.

Now you are likely wondering whether tankless or traditional water heaters are better. Here at Ace Plumbing, our expert plumbers will tell you that there is no correct answer and that each option has pros and cons. At the end of the day, the decision comes down to personal preference. Here are some pros and cons of both traditional and tankless water heaters.

Traditional Water Heaters

Traditional water heaters store and preheat 30 to 50 gallons of water in a tank. This preheated water is used whenever somebody showers, does the laundry, or uses the dishwasher. The tank then refills to be reheated once again. Traditional water heaters are typically stored indoors, inside closets or garages.


  • Lower initial cost: The initial cost of a traditional water heater is typically around half that of a tankless water heater.
  • Ease of replacement: Traditional water heaters are both easy and inexpensive to replace. Also, you can install a new electric water heater without making major changes to your home’s electrical system.
  • Good for emergencies: In an emergency, you will have a fresh water supply in the tank.


  • Higher utility bill: Constantly reheating water can lead to a higher utility bill, especially during the winter months.
  • Shorter life: Traditional water heaters last 10 to 15 years, shorter than tankless water heaters.
  • Harder to place: If you have a small space, it may be difficult to find an inconspicuous place to put your water heater.

Tankless Water Heaters

Rather than storing hot water in a tank, tankless water heaters heat your water on demand using gas or electric coils. Typically, gas units heat water faster than electric ones.


  • Lower cost in the long run: While the initial cost of installation for a tankless water heater is higher, it will save you money in the long run thanks to its higher energy efficiency.
  • Small in size: Tankless water heaters are much smaller than traditional water heaters and can be installed in more places in your home.
  • Longer-lasting: Tankless water heaters typically last over 20 years.


  • Higher initial cost: If you’re on a tight budget, a tankless water heater may not be the right choice, due to its higher initial cost.
  • Harder to retrofit: If you want to retrofit your traditional water heater with a new tankless system, things get complicated and the cost increases.
