There are various categories of electric heaters. Here are some common categories:

1. Classification of resistance heating type by heating mode:

Use the resistance wire or resistance belt to generate heat for heating. For example,the resistance wire heating element in a household electric heater. Electromagnetic induction heating type: through the principle of electromagnetic induction to make the heated object itself heating. Often used in large heating equipment in industry,such as electromagnetic induction furnaces. Infrared heating type: the transfer of heat by infrared radiation mode. Infrared bath bully is the application of this heating method.

2. Classification tubular electric heaters by structural form:

The heating element is tubular and is usually used for the heating of a liquid or a gas. Common in heating pipes in water heaters. Plate electric heater: heating plate form,heating area is larger. Can be used for the heating of the plastic machinery. Box electric heater: the whole box structure,internal heating components. It is often seen in laboratory incubators.

3. Industrial electric heaters are classified by application scenario:

Large power,suitable for chemical,oil,machinery and other industrial fields of heating demand. For example,the heating device in the chemical reactor. Civil electric heater: the power is relatively small,to meet the heating needs of the family and daily life. Like electric heaters,electric kettle,etc. Commercial electric heater: used in commercial places,such as restaurant insulation table heating,shopping mall air conditioning auxiliary heating,etc.

4. Classification by heating medium

Liquid electric heater:

Specifically pecially for heating liquids such as oil,water,etc. Often used in hot oil furnace,water heater.

Air-electric heater:

Heat up the air. Common in the air-conditioning system of the auxiliary heating,industrial drying equipment.

Solid-state electric heater:

Used for the heating of the solid matter. Such as mold heating.

For example,in industrial production,different types of electric heaters will be selected according to different process processes and heating media. For example,in the petrochemical industry,for high temperature,high pressure and corrosive liquid media,may choose special material tubular electric heater; and in the home,in order to quickly heat water,moderate power resistance tubular electric heater is usually installed in the electric water heater.
