Immersion Heaters: Everything You Need to Know

What Are Immersion Heaters?

An immersion heater is an electric heating element used to heat water in a tank or cylinder. Typically installed in hot water cylinders, immersion heaters are reliable and energy-efficient systems for producing hot water. They function by heating a metal coil that is submerged in the water, transferring heat and raising the water temperature.

Who Would Use Immersion Heaters?

Immersion heaters are ideal for both domestic and commercial use. Homeowners with vented hot water cylinders often rely on immersion heaters for a steady supply of hot water, while commercial buildings, offices, and facilities that need consistent hot water for various operations also utilise immersion heaters. They're especially useful in areas where a traditional central heating system is not in place or when additional heating support is needed.

Copper vs. Incoloy Immersion Heaters

There are two main types of immersion heaters: copper and Incoloy.

Copper immersion heaters are known for their excellent thermal conductivity and are perfect for areas with soft water. Copper’s natural resistance to corrosion makes it a popular choice for domestic use.

Incoloy immersion heaters, on the other hand, offer superior corrosion resistance and are ideal for hard water areas or systems that need to endure higher temperatures. Incoloy's strength ensures that these heaters provide long-lasting reliability in harsh environments.

Where Are Immersion Heaters Installed?

Immersion heaters are typically installed in vented hot water cylinders. They are fitted into the side or top of the cylinder, allowing the heating element to be submerged in water for efficient heating. Depending on the size and application, immersion heaters can also be used in commercial water heating systems and larger heating tanks.

Why Are Immersion Heaters Installed?

Immersion heaters are installed to provide a reliable and efficient source of hot water. They offer energy-efficient water heating with accurate temperature control. Whether used as the primary source of hot water or as a backup in case of a boiler failure, immersion heaters provide a cost-effective and versatile solution. They are especially beneficial in properties without central heating systems or for households that need an extra boost of hot water for peak demand periods.
