Tankless vs. Traditional Water Heaters: Pros & Cons

We’ve come a long way with home technology, and water heaters are no exception. Gone are the days when there was just one basic way to get hot water in your home. Now, there are multiple options, each with its own benefits and drawbacks. The decision isn’t always straightforward — choosing between tankless vs. traditional water heaters depends on your home’s hot water needs, budget, and energy preferences.
Do you go with a traditional tank water heater, which stores hot water and keeps it ready to use, or a tankless water heater, which heats water on demand? Both systems can get the job done, but there are some key differences that can impact your household’s daily routine and long-term costs. Let’s discuss the difference between tankless and tank water heater systems to help you make the right choice.
How Traditional Tank Water Heaters Work
Traditional storage tank water heaters are the most common type of water heater found in homes. They work by storing a set amount of water — typically 30 to 80 gallons — in a tank. A gas burner or electric heating elements heat the water. This keeps it at a constant temperature so that it’s ready to use whenever you need it.
Advantages of Traditional Tank Water Heaters
While storage tank models aren’t the newest technology, they still have their advantages.
- Lower Upfront Cost: Traditional tank models cost less to purchase and install compared to tankless models.
- Easier Installation: Since most homes are already designed for a tank water heater, switching to a new one is straightforward.
- Reliable Hot Water Supply: As long as the tank is full, hot water is available immediately when you turn on the tap.
Disadvantages of Traditional Tank Water Heaters
Although traditional water heaters are reliable, they can come with a few downsides.
- Limited Supply of Hot Water: Once the tank is emptied, you have to wait for it to refill and reheat before more hot water is available.
- Higher Energy Costs: Because the heater constantly warms the water in the tank, energy is wasted even when no one is using hot water.
- Takes Up More Space: Storage tank water heaters are bulky and require a designated space in your home.
How Tankless Water Heaters Work
Tankless water heaters, sometimes called on-demand water heaters, don’t store water in a tank. Instead, they heat water only when needed. When you turn on a hot water tap, cold water flows through a heat exchanger, where it’s heated by gas or electricity before heading straight to your faucets.
Advantages of Tankless Water Heaters
Many homeowners choose tankless water heaters due to their energy efficiency and convenience.
- Endless Hot Water: Since these units heat water as needed, you won’t run out during long showers or back-to-back appliance use.
- More Energy Efficient: Tankless water heaters tend to use less energy because they don’t keep a tank of water heated all day.
- Compact Size: Without the need for a storage tank, these units take up much less space.
- Longer Lifespan: A well-maintained tankless water heater can last over 20 years, compared to a lifespan of ten to 15 years for traditional models.
Disadvantages of Tankless Water Heaters
Despite their benefits, tankless heaters can have a few potential downsides.
- Higher Initial Cost: The upfront cost of a tankless unit is typically higher than a traditional tank model.
- May Need Multiple Units: If your home has high hot water demand, a single unit may not be enough, requiring multiple tankless models.
- Possible Installation Upgrades: Some homes may need upgraded gas lines or electrical work to support a tankless system.
Is It Worth Switching to a Tankless Water Heater?
Many homeowners wonder if upgrading to a tankless system is the right move. The answer depends on how much hot water your household uses and your long-term goals.
If you frequently run out of hot water or want to lower your energy bills, a tankless water heater could be a smart investment. The energy savings over time can help offset the higher initial cost, making it a worthwhile upgrade for many homes.
However, if you prefer a lower upfront cost and don’t mind waiting for a storage tank to refill occasionally, a traditional tank heater may still be the best fit for your needs.
Gas vs. Electric: Which Water Heater Is Best?
Once you’ve decided between tank and tankless heaters, the next choice is the power source. Both gas water heaters and electric water heaters have advantages, but the right one depends on your home setup and energy preferences.
Gas Water Heaters
- Heat water faster than electric models
- Work during power outages if they don’t rely on electricity for ignition
- More energy efficient than electric models for homes with high hot water demand
- Higher installation costs if new gas lines are needed
Electric Water Heaters
- Electric tankless water heaters typically have a lower initial cost compared to gas tankless water heaters
- More energy efficient in areas where electricity is cheaper than natural gas
- Easier to install since they don’t require gas lines
- May take longer to heat water compared to gas models
Choosing the Best Water Heater for Your Home
Ultimately, deciding between tankless vs. traditional water heaters comes down to your household’s needs. If you want an instantaneous water heater that provides endless hot water and saves space, a tankless model might be worth it. If you’re looking for a more budget-friendly option and don’t mind a large storage tank, a traditional heater could still be the right choice.
