Tankless water heaters work quite differently when compared to the traditional tanked water heaters. They don’t hold hot water in a large tank. Instead, they’re used only when there is a demand for hot water. This is usually when you want to take a shower or use certain appliances

To have a refreshing hot shower, all you need to do is simply turn on the tap. The tankless water heater will heat the water passing through it, giving you hot water when you need it. With tankless water heaters, you don’t need to heat the water throughout the day and night.

In the tankless water heating systems, a burner usually ignites upon getting a signal indicating the need for hot water. The water then passes over a heat exchanger made of aluminum, which heats the water directly. The system can be put to a standby mode by shutting off the hot water supply.

The hot gases resulting from the whole operation don’t accumulate inside the home. They are exhausted outside the house with the help of a vent. Now, let’s understand the various stages involved in the operation of tankless water heaters:

Stage 1

To begin operating the tankless water heaters, you turn on the hot water knob. This would allow the water to flow through the pipes. There are tankless water heaters with single or dual knobs. So, you’ll need to make sure that you’ve turned on the appropriate knob to allow water to flow through.

Stage 2

In case of regular water heaters, you expect hot water to flow from the tank. With tankless water heaters, water flows through sensors that trigger the heating process. Thus, the flowing water is heated with the help of the system.

Stage 3

The internal system promptly ascertains the required heat of the burners once it is triggered. This helps in heating the water to the desired temperature. All the work is done by either a gas burner or an electrical component. The constant flow of hot water is maintained in this way. Because of this efficient system, you don’t need to wait for the tank to fill up.

Stage 4

When the burner starts heating the water, it goes around a heat exchanger. Once it achieves the set temperature, water exits the heater and travels through the pipes. It continues to flow until it exits through the tap.

Stage 5

You can enjoy a constant flow of hot water by using a tankless water heater. Once you no longer need hot water, you can turn off the tap. The tankless water heater would then shut down automatically. You can thus save a significant amount of energy by using such water heaters.

You might be wondering whether or not to have a tankless water heater. Before you arrive at a decision, it would be a good idea to know how it works. You’d also want to know the benefits of having one at your home or office.

As it uses far less energy to operate than the traditional water heater, you’d certainly save big on energy. Another major benefit is that you can enjoy a steady stream of hot water for your use.
