If you’re thinking about upgrading your water heater, you’ve likely heard about the growing popularity of tankless systems. Tankless water heaters, also known as on-demand water heaters, offer several modern conveniences and energy-saving benefits.
But are they the right fit for your home and household needs? In this post, we’ll break down what you need to know about tankless water heaters so you can make an informed decision.
Benefits of Going Tankless
1. Endless Hot Water Supply
With a tankless system, you don’t run out of hot water like you might with a conventional tank. This is especially useful for larger households or families with back-to-back showers, loads of laundry, and dishes.
2. Energy Efficiency
Tankless water heaters are typically more energy efficient because they only heat water as needed. According to the US Department of Energy, homes that use 41 gallons or less of hot water daily can be 24–34% more energy efficient with a tankless system than with a traditional tank model.
3. Space Savings
These systems are compact and wall-mounted, freeing up valuable space in utility rooms, garages, or closets. Their sleek size makes them ideal for smaller homes or apartments.
4. Longer Lifespan
A tankless water heater can last up to 20 years—much longer than the 10 to 15 years you can expect from a traditional tank system. This longer service life can offset the higher upfront cost.
5. Reduced Risk of Leaks and Water Damage
Because tankless systems don’t store water, there’s less risk of catastrophic leaks or tank ruptures, which can be costly and damaging.
Things to Consider Before Switching
1. Higher Upfront Cost
Tankless water heaters cost more to purchase and install. The installation often requires plumbing and electrical upgrades to handle the unit’s demands, especially if switching from a gas to electric system or vice versa.
2. Limited Flow Rate
While they provide endless hot water, the total flow rate (how many fixtures can use hot water simultaneously) may be limited. If you have multiple people using hot water at the same time, you may need a larger unit or even more than one system.
3. Maintenance Requirements
Tankless systems require periodic descaling, especially in areas with hard water. Mineral buildup can reduce efficiency and damage the unit if not maintained properly.
4. Gas Line or Electrical Upgrades May Be Needed
Depending on the model, you may need to upgrade your home’s gas line or electrical panel. This adds to installation costs and could require permits or inspections.
Is a Tankless Water Heater Right for You?
You may benefit from a tankless system if:
- You want to save energy and lower long-term utility bills.
- You have limited space for a traditional tank water heater.
- Your household doesn’t use excessive hot water simultaneously (or you’re willing to invest in a high-capacity system).
- You plan to stay in your home long enough to justify the initial investment.
However, if you’re on a tight budget, need to run multiple hot water fixtures at once, or don’t want to worry about additional maintenance, a traditional tank system may still serve your needs better.
