How Does an Immersion Heater Work?

An immersion heater works by using an electric heating element to heat water directly in a tank or container.

Understanding the basic functioning of an immersion heater

An immersion heater, simply put, is a device installed inside a tank or container to heat a liquid. The heater operates by converting electrical energy into heat, which is then transferred to the fluid that surrounds it.

A thermostat attached to the immersion heater regulates its operation based on pre-set temperature levels.

The core component of an immersion heater is the heating element composed of metal loops. These loops generate heat when electric current passes through them due to resistance — similar in function to elements found in common household appliances like hair dryers and ovens.

This process ensures your supply of hot water remains constant and ready-to-use.

How it heats water and provides hot water supply

An immersion heater works by directly heating the water in your tank, providing you with a constant supply of hot water. When you turn on the immersion heater, an electric current passes through a heating element that is immersed in the water.

This heats up the surrounding water, gradually raising its temperature to your desired level. The heated water then rises to the top of the tank and flows out whenever you open a tap or use a shower.

To ensure that the hot water supply remains consistent, it’s important to run the immersion heater for at least two hours each day. This allows enough time for the entire volume of water in your tank to reach and maintain its desired temperature.

Keep in mind that different factors such as insulation quality and age of your tank can affect how long it takes for the water to heat up.
