If you’ve recently made a big move to a new house with a tankless water heater or just decided to install a new one, you’re probably scratching your head in confusion. Perhaps after looking at the mystical heater from the future, you’re wondering, ‘how does a tankless water heater work?’

Well, let us help you out!

What is a Tankless Water Heater?

Just like how the name suggests, tankless heaters store and heat water. However, the water is not kept in a tank. The pipeline is systematically connected so that you can get hot water on-demand! This means you can get hot water whenever you want, without waiting for it to heat in real-time. This helps to save time and electricity since the heater doesn’t continuously heat the water all day long.

How Does a Tankless Water Heater Work?

Tankless water heaters contain multiple sensor points inside their bodies. This means that, consequently, through the help of gas or electricity, they instantly convert the cold water to hot. When you go to turn the tap on for hot water, one of the sensors immediately sends a signal.

In the case you use a water heater, the burner inside its body will heat the water. Whereas on the other hand, if you power the tankless water heater through electricity, a heating coil will be used.

Step-by-Step Guide on How a Tankless Water Heater Works

If you’re still confused about the itty bitty parts of the process, don’t worry. We’ve got you covered. Have a look at the following step-by-step guide to see how a tankless water heater works.

Step 1 — Hot Water Tap: ON

Start off by turning on the tap, specifically the one for hot water. This is usually on the right side of the sink.

Step 2 — Water Flows to the Heater

When the faucet is turned on, the water flows through the heater. In real-time, however, this process is done in an instant as the water flow doesn’t stop.

Step 3 — Sensor Detects Water Flow

The built-in sensors automatically detect the water. This helps them to prepare as the water flow heads towards the direction of the heater.

Step 4 — The Burner Automatically Turns On

Once the water reaches the heater, the burner inside also instantly turns on. As a result, the water gets hot on impact.

Step 5 — Endless Stream of Hot Water

And Voilà! You’re met with an endless stream of hot water. Moreover, this makes it easy for you to use hot water any time of the day, no matter what.
