Hot water is an essential part of your daily routine. From morning until night, you rely on your home’s water heater to provide reliable hot water when you need it. After all, there’s nothing worse than jumping in the shower and being blasted with cold water.

For some homeowners, the best way to keep the hot water flowing is with a tankless water heater. These systems are also known as “on-demand” water heaters, as they only provide hot water when needed.

If you’re interested in replacing your water heater with a tankless model, it can be helpful to familiarize yourself with these systems before you make a decision. So, how does a tankless water heater work? What can you expect from installing one of them?

Let’s go over what a tankless water heater is and how it works!

What Is a Tankless Water Heater?

Do you currently have a traditional tank water heater in your home? You might be surprised to learn that there are many differences between traditional water heaters and tankless models. Consider using this guide to learn more about how these systems are different from one another:


How Do Tankless Water Heaters Work?

If you ask a friend what they think about their tankless water heater, they’ll probably rave about its energy efficiency and space-saving design. However, they might not know about the ins and outs of tankless water heaters.

So, how does a tankless water heater work, exactly? The good news is that the process is pretty straightforward. First, when the hot water tap is turned on, cold water is sent to the unit. From here, the heat exchanger inside the water heater is warmed up with a gas burner or electric element.

The heat exchanger will heat the water to a preset temperature. Once the water has reached the desired temperature, the hot water flows to the faucet or shower for you to enjoy.

How does a tankless water heater work in comparison to a traditional unit? All-in-all, these systems work much in the same way. However, traditional units have to heat much more water to ensure it’s ready for use.

Is a Tankless Water Heater Worth It?

Now that you know what a tankless water heater is, you’re probably wondering if you should have one installed in your home. When it comes down to it, there are many benefits of tankless units that are worth considering. For example, these systems are known for being energy efficient, which can translate to excellent energy savings over time. You’ll also receive hot water on demand, which can be advantageous if your household tends to use tons of hot water.

However, it’s also worth noting that tankless water heaters can have their fair share of problems if they aren’t sized correctly for a home. When installing a tankless water heater, it’s important to ensure that it has a flow rate that matches your needs.

The “flow rate” measures how much hot water a water heater can provide in gallons per minute. If you install a tankless unit that’s too small for your needs, you can end up with cold water when running the dishwasher, shower, and other appliances simultaneously.

Larger homes will likely need to have tankless water heaters installed with higher flow rates. Your local plumber can help you find the right-sized water heater to fit your specific needs.
