Electric Heater has been used as a source of heat in homes as well as industries for decades. These electric heating devices use electrical energy as an input source of power and transform it into thermal energy to heat the air or things in a specific space. All electric heaters use one or more of the three basic heat transmission mechanisms: convection, conduction, or radiation.
Electric Heater – Concept of Electric Heating
The process of transforming electrical current into heat energy is known as electric heating. An electric heater has a built-in heating element, called an electrical resistor. When current passes through that heating element (resistor), heat is generated.
This method is extensively used in a wide range of domestic applications. Cooking on an electric burner, boiling water in a kettle, and, of course, keeping your home warm are all examples.
Electric industrial heaters are used in different applications to raise the temperature of an object or process. Lubricating oil, for example, needs to be warmed before being given to a machine, or a pipe requires the use of a tape warmer to prevent it from freezing in the cold.
Electric heaters and radiators function similarly to plumbed central heating radiators, with one significant difference: they do not rely on a boiler and a network of pipes to deliver heat. This is advantageous since it provides more control over the temperature of each unit. It also enhances reliability since if your boiler fails, your heating system continues to function normally, keeping your home warm.
How do Electric Heaters Work?
Electric heaters are stand-alone machines that use heating elements to heat a core. Oil-filled and dry cores are the two major types of cores used in electric radiators and heaters. Most of the reputed electric heater manufacturers in India use ceramic to build dry core heaters and radiators which makes them lightweight and leak-free.
When the heater is turned on, power is transferred through the heating element, which uses electrical resistance to generate heat. As the element heats up, the heat energy is transmitted to the core, which is then conducted by the heater’s casing before being transferred to the surrounding air and maintaining a beautiful, comfortable temperature in your home.
Electric Heaters for Industrial Use
Many industries use heat in their industrial processes. Whether it’s eliminating leftover moisture from a part’s surface, drying a coating on cable assemblies, or preheating metals during a forming process, heating is a key component. When selecting heating technology, end users must consider what they want to obtain out of their process. It can be difficult to determine which technology is best suited for the procedure.
When choosing heating equipment, factors such as maintenance, safety, and repeatable controls must all be considered. The electric industrial heater is one of the most common industrial heating technologies. This heater is a versatile option that can be easily integrated into a variety of industrial applications.
Features of an Electric Heater
These devices use an electrical element to heat a highly conductive core, such as thermal fluid or ceramic, which is far more efficient than heating water and delivering it through a network of pipes, resulting in lower operational costs when compared to traditional plumbed heaters and radiators.
Electric heaters are an eco-friendly heating alternative for your house due to their absence of combustion and hazardous emissions, allowing you to save money and the environment!
Ease of Maintenance
Electric heaters make industrial equipment easier to maintain. Electric heaters do not require a unique monitoring system or valves to deliver hot air to a process.
Ensure Safe Operation
When using heat in an industrial process, safety is always a concern. Operators are subject to specific operational factors while using technologies such as gas combustion. Operators can potentially harm the equipment they are working on and become injured if not managed appropriately.
Types of Electric Industrial Heaters
Electric heater types are determined by a mix of design and application. The most common types of electric heaters in use are:
Electric Fan Heaters
Electric Fan Heaters are made up of a heating element that generates thermal energy by passing an electrical current through a resistive element that generates heat through the Joule effect. They also have an electric fan that blows air across the heating element and distributes hot air throughout the room. These heaters are classified as convection heaters because they provide a consistent heating effect and, depending on how well the space being heated is insulated, can maintain comfort levels even after the unit is turned off. Many of these heaters are portable and are powered by a normal outlet connection.
Ceramic heaters are a type of electric heater in which the heating element is composed of positive temperature coefficient (PTC) ceramic material. These heaters are available in both a convective form that uses a fan to transmit heat to the room and a radiant form that performs similarly to the previously described electric infrared heater. This sort of heater is safer because the heating element is made of ceramic. When polycrystalline ceramic heats up, its thermionic resistance begins to increase. This leads to a self-limiting state for the heating element, prohibiting the ceramic from absorbing more heat from the electrical resistance and, as a result, limiting the heater’s temperature.
Installing electric floor heaters, which employ electric heating cables or floor heating wires buried in the flooring of rooms, is another electric heater alternative. These heaters are frequently referred to as in-floor radiant heating, although as previously stated with electric baseboard heaters, the term radiant – which normally refers to heat transfer via radiation – is less applicable in this case. This type of heating system employs both conduction and convection. Electric floor heating can be an energy-efficient option that provides an even, comfortable heating effect in a room; however, it is more difficult to install on existing floors and is therefore frequently used in new construction situations.
Electric Water Heaters
Electric water heaters, while technically classified as electric heaters, do not heat the air or space in a room. Instead, they heat water for bathing, washing clothes and dishes, and other water needs.
