How Does an Immersion Heater Work?

The most common immersion heaters for water, oil and other liquids use electricity to power the heating element. Electricity offers stable heating in a range of kilowatt ratings. Depending on the purpose of the equipment, the heater can be used to maintain a consistent temperature, vary the temperature or quickly reach the desired temperature.

Most immersion heaters are submerged in the product, while others use a process liquid to transfer heat from the heater to the particular product. Either way, a durable sheathing is required to protect the electric heating element.

A complex control system carefully adjusts the power to the heating element. Combined with a thermocouple or other temperature-sensing device, the control system helps control the immersion heater to provide accurate, repeatable results.

Because immersion heaters rely on electricity to power the heating element, you won’t have to worry about combustion hazards. This line of industrial heaters is particularly popular when heating combustible liquids or gases. Instead of relying on an open flame, electric heaters use conduction and convection to thoroughly heat your chosen product.
