What is the purpose of an immersion heater?

An immersion heater is designed to heat water directly using electric elements. This type of heater typically consists of a metal element that is submerged directly in the water, allowing it to transfer heat efficiently. When an electrical current passes through the element, it generates heat, warming the water surrounding it. This direct heating method is effective in achieving a higher temperature in a relatively short amount of time compared to other methods.

The direct heating mechanism is particularly useful in applications where rapid heating of water is required, such as in storage tanks or individual vessels. Immersion heaters are commonly used in residential systems for various hot water needs due to their straightforward design and effective performance.

Additionally, while mixing cold and hot water, regulating temperature, or filtering impurities are important aspects of a plumbing system, they do not specifically pertain to the primary function of an immersion heater.
