Electric heaters are an important item we use in our everyday life - You might not even realize that you use one.
These types of heaters act as an alternative heat source to other conventional methods like wood fires, gas fires, and water heating. Electric heating is a tried and tested method and is used worldwide for a variety of reasons. These types of heaters can provide a fiscal heating option as they allow for greater operational control.
How are they Made?
The process of electric heating involves electrical energy getting converted into heat. Electric heaters contain a heating element enclosed inside a protective casing. The heating element can be created from metal like Nichrome, resistance wire or etched foil, ceramic, polymers (rubber), or a composite material. This element, regardless of its physical makeup, will convert electricity into heat through a resistive or Joule heating process.
The heating element is often exposed on one side through a protective grill to allow the heat to disperse into the environment.
What Types of Electric Heaters are There?
The kinds of electric heater are numerous, and the list below provides the main types available:
- Space heaters (Portable and not secured to a wall).
- Heat pumps (Take heat from one environment and push it into another)
- Wall mounted heaters (Generate and circulate the hot air).
- Outdoor heaters (Tall tower with enclosed heating element)
- Electric arc furnaces (Used in industrial environments).
- Immersion heaters (Used to heat water).
These are not the only heaters made, anything that contains a heating element and powered by electricity would be considered an electric heater.
What are the typical common uses?
The primary use of electrical heaters is obviously to provide a heat source someplace that has none. Heaters that are built to heat a particular area mainly are used in homes, offices, small factories, etc. They are usually portable to be able to take into different rooms when a direct heat source is needed or mounted into the walls and turned on when the temperature drops.
Industrial heaters have a wider and more technical application for their heating benefits. Processes such as arc welding and other high-temperature actions (soldering, casting, etc.) can make use of electric heating either using a direct current or a through a dielectric loss method.
Immersion heaters perform the heating of water through the immersion process. An electrical heating element is placed within the water in a secure container and then produces heat which in turn raises the temperature of the water. A combination of sensors and temperature controls allow the water temperature to be changed as desired.
As a method of heating used worldwide and that has been thoroughly tested, electric heaters are extremely useful for many aspects of our daily lives and industrial purposes.
