Tank vs. Tankless Water Heaters: Which One Is Right for You?

Hot water is such a daily convenience now that most of us don’t even think about it – until it’s suddenly gone. Then, we find ourselves scrambling to find a plumber and determine whether to repair or replace the unit.

If the old unit is far gone or awfully out of date, then a replacement is typically the cost-effective and prudent option. Then, the question often comes down to “tank or tankless?”

In this brief article brought to you by Texas Rooter, we share our case for each. The decision ultimately depends on your needs and preferences, as well as the layout and condition of your plumbing system.

Here’s How Each System Works

Tank-style water heaters are the traditional version that most of us grew up with. They store a large amount of water (typically 40 to 80 gallons) in an insulated tank and keep it heated at all times. When you open the tap, that hot water flows from the tank to your faucet or shower.

Tankless water heaters, also known as on-demand units, eliminate the storage part of the old process. Instead, they heat water as it passes through the piping. When you turn on the tap, burners or electric elements kick on to heat water on the spot.

Both systems get the job done; that is, they heat water and get it to your faucets, taps, and showerheads. The difference lies in how they fit your lifestyle, usage habits, and home layout.

The Case for the Tank-Style Water Heater

If you prefer simplicity and reliability, then a tank water heater may be your best bet. These systems have been around for many decades and they have fewer complex parts. This makes them easier and often cheaper to install. Any qualified plumber can repair or replace one without much fuss. 

Moreover, a tank-style water heater might be right for you if you prefer:

• Lower Upfront Cost: Tank-style systems are more affordable to buy and install.
• Straightforward Maintenance: Most plumbing companies are familiar with them, and replacement parts are easy to find.
• Consistent Temperature: Once the tank is full of hot water, you get an immediate and steady supply of hot water. When the power goes out, you still have spare in the tank.
• Easier Retrofit: If your home already has a tank, then swapping in a replacement is a piece of cake.

However, tanks do have downsides. They take up more space, waste energy keeping that massive tank of water hot when it’s not being used, and can run out of hot water if demand exceeds capacity.

The Case for the Tankless Water Heater

A tankless water heater is a more modern solution and appeals to those who prioritize energy efficiency and space savings. Because it heats water only when needed, tankless units can dramatically reduce standby energy losses.

Additionally, a tankless water heater might suit your home if you prioritize:

• Unlimited Supply: As long as your system is properly sized, you can shower, wash dishes, and do laundry without running cold.
• Longer Lifespan: Tankless models can outlast most traditional tanks by nearly a decade.
• Compact Design: Mounted on a wall, tankless units frees up valuable floor space. Perfect for properties where square footage counts.

The trade-off is cost. Tankless systems are pricier to install, and even costlier if switching from a traditional tank. Moreover, water heater repair can get tricky as parts are harder to find.
