Tank vs. Tankless Water Heaters: Is It Time to Make the Change?

March 11, 2025

Upgrading your home’s hot water system is a big decision. If your current water heater is aging or you want to improve energy efficiency, you may be wondering if now is the right time to switch to a tankless water heater.

Both traditional tank and tankless (on-demand) water heaters have benefits and drawbacks. The best choice depends on your household size, water usage, and long-term energy goals. Here is what you need to know before making the switch.

How Do They Compare?

Traditional Tank Water Heaters

A tank water heater stores and heats a set amount of water, usually between 40 and 80 gallons. When you use hot water, the tank refills and reheats so that hot water is ready when needed.

Pros:

  • Lower upfront cost
  • Simple and reliable
  • Can handle high water usage if the tank is large enough

Cons:

  • Hot water can run out during heavy use
  • Higher energy costs due to standby heat loss
  • Shorter lifespan (typically 10 to 15 years)

Tankless (On-Demand) Water Heaters

A tankless system heats water only when needed, rather than storing hot water in a tank. Water is instantly heated as it moves through the system, providing an endless supply without standby energy loss.

Pros:

  • Uses less energy, lowering utility bills
  • Provides unlimited hot water
  • Takes up less space
  • Lasts longer (typically 20 years or more)

Cons:

  • Higher upfront cost
  • May require upgrades to gas or electrical systems
  • Slight delay before hot water reaches the tap

Why Consider an Upgrade Now?

If your current water heater is aging or inefficient, now is a great time to invest in a better system. Many homeowners are switching to tankless water heaters to reduce energy costs, improve convenience, and free up space.

A tankless water heater may be the best choice if:

  • Your family uses a lot of hot water and you often run out
  • You want to lower energy costs and improve efficiency
  • Your current system is aging and may need replacement soon
  • You want to free up space by removing a bulky tank

Some energy-efficient water heaters may also qualify for rebates or incentives, helping to reduce the cost of upgrading.

Is It the Right Choice for Your Home?

Upgrading to a tankless system can be a smart investment, but the best choice depends on your household’s needs. If your current water heater is still working well and meets your needs, keeping it may be the right choice for now. If you are looking for a system that will last longer, provide unlimited hot water, and lower your energy costs, tankless water heaters are worth considering.
