Why Should Upgrade to a Tankless Water Heater?

Water heaters traditionally feature a large tank of standing water that is heated and reheated throughout the day. When someone needs it, the water is already warm and ready for use.

However, homeowners can now choose tankless water heaters, and it’s easy to see why so many people prefer them. From energy savings to increased lifespans, tankless water heaters are an attractive option. Whether you’re in Memphis, TN, or Bangor, ME, a tankless water heater might be the right fit for your home.

Traditional water heaters use a tank filled with standing water. The system heats the water continuously throughout the day so that it’s ready when someone needs it. But the hot water is not instant, and there are other drawbacks as well.

Tankless water heaters, on the other hand, create warm water almost instantly. Rather than reheating the water throughout the day, tankless water heaters produce hot water on-demand using electric coils or a high-power gas burner.

There are many benefits to using a tankless water heater, but there are some drawbacks too. You’ll want to look at all of the variables to decide whether a tankless water heater is right for your home. 

The Advantages of Tankless Water Heaters

There are many reasons people are switching over to tankless water heaters. Here are some of the top benefits of using a tankless water heater in your home:

Instant Hot Water

One of the biggest benefits of a tankless water heater is that the hot water is almost instant, so there’s no waiting involved when you need it. There’s also no shortage of hot water as long as you’re not using it for multiple purposes simultaneously. 

Space Saving

Tankless water heaters are much smaller than traditional water heaters because they don’t need a large tank to hold the heated water. Water heater tanks are often 60 inches tall and about 24 inches wide, so they can take up a lot of precious space in your home. 

Having a tankless water heater is much more convenient, and the small size makes it easier to maintain. 

Increased Service Life

Another benefit is that tankless water heaters typically have a longer service life than their bulky counterparts. A water heater with a tank will usually last around ten years, while a tankless option has a lifespan of about 20 years. 

Decreased Maintenance

Tankless water heaters also require less maintenance overall. You should have your traditional water heater checked every year by a technician, but tankless water heaters only need to be inspected every four to five years.

This reliability can save you money and hassle in the long run, and you can have peace of mind knowing your tankless water heater is likely to run smoothly for years. 

Lower Monthly Cost

One of the biggest advantages of tankless water heaters is that they cost less money to operate. This efficiency means your energy bills will be less expensive every month.

They cost less because traditional water heaters need to use energy constantly to heat the water in the tank and keep it ready. Because tankless water heaters create warm water instantly, they don’t waste energy when not in use. 

The Drawbacks of Tankless Water Heaters

Of course, like anything else, there are some drawbacks to tankless water heaters, and you’ll want to consider your needs to decide whether they’re right for you. Here are some disadvantages of using a tankless water heater in your home:

Higher Initial Cost

Probably the biggest drawback of a tankless water heater is that it costs more upfront. While you will enjoy energy savings down the line, it can take some time to make up the difference in price between a tankless water heater and a traditional one. 


It can also be a little more challenging to get lukewarm water from your tankless water heater because of how it operates. Additionally, if multiple people are using the hot water at once, you can experience inconsistent temperatures.

However, as long as people are using the hot water back-to-back (not at the same time), the hot water supply from your tankless water heater is unlimited. 


Installation can also be a concern for tankless water heaters. You may need a technician to install a water softener along with it to get it to work properly. A water softener will remove sediment and chemicals. However, this may not be necessary if you already have one installed in your main water line.

Additionally, you might need a plumber to reroute your gas lines, but an electric tankless water heater can be an excellent solution for this concern. There is also an increased need for venting when using a tankless water heater. 

No Hot Water During a Power Outage

Tankless water heaters require energy whenever they’re in use and don’t hold a reserve of warm water. This drawback means that when a power outage occurs, hot water won’t be available.
