Whether it’s for residential hot water systems, commercial boilers, or industrial fluid heating, immersion heaters play a vital role in delivering safe and consistent heating performance.

What Is an Immersion Heater?

An immersion heater is an electric heating element that is submerged directly into a liquid, such as water, oil, or chemicals, to heat it efficiently. These heaters convert electrical energy into heat and are widely used in:

  • Domestic water heating systems

  • Commercial boilers

  • Industrial chemical tanks

  • Oil heating units

  • Food processing equipment

Immersion heaters are typically made of stainless steel, copper, or Incoloy for corrosion resistance and come in different forms such as screw plug, flanged, and over-the-side configurations.
