How does a Tankless Water Heater Work?

In today's fast-paced lifestyle, everything gets done in the blink of an eye. From ordering a meal to booking a flight, you don’t need to wait for anything in your life. Then why should you wait for hot water in the bathroom?

This is why you need tankless water heaters! Tankless or online instantaneous geysers are compact, lightweight water heating units that provide you with hot water instantly. That means you will never have to keep waiting in the shower.

In this blog, we will delve deeper into tankless water heaters and explain their working mechanism. We will also get you acquainted with Racold's Aures range of tankless or online instantaneous geysers.

Components of a Tankless Water Heater

Before understanding the working of a tankless water heater, let’s take a look at its components! In this section, we will explain the role of key components in a tankless or online instantaneous geyser. So, let’s get started!

Inlet pipe –The inlet pipe allows cold water to enter the tankless water heater.

Outlet pipe –Hot water exits the tankless geyser through the outlet pipe.

Heating element –In the case of electric water heaters, the heating element is responsible to heat the water.

Thermostat –The role of the thermostat in a tankless electric water heater is to keep a check on the temperature. It makes sure that the water doesn’t get overheated and you get the perfect hot shower experience.

Working Mechanism of a Tankless Water Heater

The most distinguishing factor in the working of a tankless electric water heater is that it doesn’t need a storage tank to store hot water.

When you turn on the faucet, cold water flows into the tankless water heater through the inlet pipe. Here, the heat from the heating element gets transmitted to the water.

In the Aures 5.5kW electric water heater, the water gets heated at a lightning-fast speed. This is because it is equipped with a powerful heating element of 5.5kW.

Unlike the tank-type geysers where water is stored and continuously heated in the tank, tankless geysers heat water on demand and prevent standby heat loss. This conserves energy and enables greater savings.
