Considering upgrading your water heater this spring? If you’re changing out your old water heater, you should consider upgrading to a tankless system. In this blog, we’ll review the benefits of tankless water heaters, and why you should consider one for your home.

What are tankless water heaters?

Tankless water heaters go by several names, including:

  • Demand-Type Water Heaters
  • Instantaneous Water Heaters

No matter what they’re called, these systems are a new type of residential water heater that heats up water without storing it in a tank. Instead, the system runs cold water through a series of superheated internal pipes, quickly warming it to the desired temperature before sending that now-heated water to the faucets and shower heads of your home.

  • In a gas demand-type system, this heating is accomplished through the combustion of natural gas. The water is then pushed past gas burners.
  • In an electric tankless system, this heating is accomplished by running the water in pipes past heating elements.

This method of heating water distinguishes this type of water heater from “traditional” water heaters, which typically refers to systems that heat water and then store it for future use in a tank.

What are the advantages of a tankless water heater?

Tankless water heaters have several advantages over standard water heaters. Here are four reasons you should strongly consider replacing your aging traditional water heater with a demand-type system:

The benefits of tankless water heaters include energy-efficiency, endless hot water, and—as seen in this image—space savings.


Tankless systems are more energy-efficient than standard water heaters. They use up to 30% less energy than regular water heaters, which can amount to $100 per year in savings. Over the course of the lifespan of the system, those savings can really add up.

If you’ve been looking for ways to make your home more energy-efficient, a tankless water heater is a great place to start. Give Southern a call to learn about other ways you can start saving.

Endless hot water supply

Tankless water heaters are also known as “demand-type water heaters.” This is because, true to their name, they can provide your home with hot water as its needed at the tap or shower head. Since the system heats water as needed, there’s no “running out” of hot water like with standard water heaters.

With an endless hot water supply, your entire family can take showers in the morning without the last person feeling like they’re taking an ice bath.

Less floor space

Most tankless water heaters are wall-mounted, and can go inside your garage, washroom, or even on the side of your home. This frees up the floor space used by your current water heater.

In addition, tankless water heaters don’t carry some of the same risks as standard units. For instance, tankless systems can’t “burst” and flood your home like a tank system can if not maintained.

Systems last longer

On average, tankless water heaters last almost twice as long as standard water heaters. With standard systems, that combination of stored water, heat, and metal can only last so long, even with a sacrificial anode rod. A tankless water heater, in contrast, can last up to 20 years, providing your home with great value for decades to come.

Is a tankless water heater worth it?

We’ve talked about the benefits. So, what are the downsides of a tankless water heater? For one, demand-type systems are typically more expensive than “tank” water heaters. In some cases, the system and its installation can cost twice that of a traditional water heater.

However, it’s worth noting that the system’s improved lifespan and energy-efficiency will typically make up that difference over time. In other words, this is the type of home here in Louisiana where a tankless water heater probably fits best:

  • You plan on staying in your home for the foreseeable future, which means you’ll be around to inevitably recoup the costs through lower utility bills and the extended lifespan of the water heater.
  • You have a large family, and your cumulative morning water use makes a standard water heater impractical.
  • You live in an area of the state where municipal or utility rebates are available to homeowners who upgrade to an energy-efficient water heater.

As with most things in your home, be sure to take the long view when it comes to making an upgrade: even though a demand-type system might cost more upfront, the benefits of tankless water heaters may make one well worth the cost to you.
