Many might view an electric heater as unnecessary in today's world, where most buildings feature advanced central heating systems. However, these heaters can actually offer an efficient way to conserve energy while providing effective warmth. Electric heaters serve as a smart complement to central heating systems, delivering personal comfort and maintaining a consistent temperature, yet consuming less energy. The significant advantage of using an electric heater is its potential to reduce heating costs.
At times, temperatures aren’t sufficiently low to activate a central heating system, resulting in discomfort. Although adding clothing layers can help, it’s not always feasible for every scenario. An electric heater offers a practical solution, fostering a snug and cozy atmosphere and enhancing work or leisure activities.
If only one person is home, opting for an electric heater may be more economical than running the entire central system. This is particularly beneficial when working from a home office, spending time in a bedroom, or in the kitchen. Modern electric heaters are lightweight and portable, easily adaptable to various spaces.
The U.S. Department of Energy states that heating and cooling account for more than half of an electric bill. A viable method to cut these costs is by incorporating electric heaters. The energy department indicates that about $1800 annually is spent on an electric furnace. Given electricity costs of $0.12 per kilowatt hour, using an electric heater in a single room for 12 hours daily between November and March could cost around $315, representing significant savings.
Climate significantly influences the efficacy of electric heaters. In areas like California, where temperatures stay mild, heating might not be necessary for extended times, reducing the need for electric heaters. However, in colder states such as Minnesota, Wisconsin, Idaho, and North Dakota, where temperatures drop below freezing, electric heaters are key in achieving cost savings. It should be noted that electric heaters are optimal for heating individual rooms and should ideally enhance a central heating system.
Enhancing electric heater efficiency involves several practical measures when used alongside central heating systems. The major benefits include lowered heating expenses while heightening convenience and comfort. It’s crucial to follow certain methods and practices for energy conservation and efficient electric heater integration.
Implementing a programmable thermostat is a savvy move to cut down heating expenses. These thermostats, sometimes referred to as setback or clock thermostats, let you alter temperatures during various times of the day, permitting cooler temperatures when the room is unoccupied. Adjusting the thermostat to 10 to 15 degrees lower during such times facilitates a potential 5 to 15 percent reduction in heating costs, as per the U.S. Department of Energy.
Another effective method is to lower temperatures in a building when only certain rooms are occupied, utilizing electric heaters to ensure those spaces remain warm and comfortable. Identifying used rooms and equipping them with the appropriate electric heaters is essential for this system’s effectiveness.
In this era of emphasizing environmental stewardship, electric heaters offer the benefit of heating specific areas more sustainably. No energy spent on these heaters is wasted, and, as they don't utilize natural gas or oil, they emit no air pollutants. Infrared heaters are particularly popular for being environmentally friendly devices.
Electric heaters function on principles similar to central heating systems, but on a smaller scale. Given the extensive options, it’s essential to select a model tailored to your specific needs. Making impulsive purchases should be avoided; careful consideration ensures an optimal match.
The essential element in all heaters is an electrical resistor that transforms electrical energy into heat. Resistance may often seem negative, but in heater technology, it is vital for heat generation. A high-resistance material obstructs current flow, converting that energy into heat. Thus, more resistance equals higher heat output.
The resistor in an electric heater performs multiple roles. It regulates the electric current flow and, usually crafted from carbon, ensures voltage consistency and provides spike protection. The quality of the resistor determines the efficiency and longevity of the heater.
Different forms of resistors are available including ceramic cylinders, mica-embedded wires, ceramic-coiled, tubular core, or those insulated with magnesium oxide powder. Ceramic, an excellent heat conductor and insulator, allows resistors to use moderated power without reheating. Mica-embedded wire resistors are cost-effective and offer high resistance for lower power. Tubular core resistors vary in diameter based on their use and can handle significant power loads. A specific tubular model uses magnesium oxide insulation to cover and assist the electric wiring in conducting heat.
Upon activation, a heater's electrical current warms its nichrome wire component, the heating coil. The resistor generates heat while the unit’s fan draws air past the heating elements, warming a space similar to a hair dryer through convection heating.
Lacking a fan, the heater relies on air passing over coils and venturing outward, dubbed as radiant heating. This design suits smaller areas as it heats nearby air, which takes time to affect larger spaces. A key example of radiant heaters includes the electric baseboard model using natural convection at a lower cost.
Different electric heaters are available with or without thermostats. Models lacking thermostats merely heat a room with a basic on/off switch. In contrast, those with thermostats include a digital display or dial for specific temperature settings, automatically ceasing operation when the desired warmth is achieved. Most modern heaters boast thermostats, frequently highlighted in marketing materials.
Historically, the term electric heaters or space heaters may carry negative connotations due to older, low-quality versions. However, advancements have significantly enhanced modern electric heaters. Today, a wide array of options complicate the selection process compared to decisions made half a century ago.
Before purchasing a new electric heater, determining the required heat output is crucial. The selection varies based on the room’s size where it will be used. Traditional heaters generally warm up to 400 square feet, while more powerful units cover up to 1000 square feet. Measuring your space helps avoid over or under-buying. Generally, unless heating a large area like a milking barn, a compact heater suffices.
After determining room size, evaluate the heater’s features. Most are marketed with energy-saving features, managing electricity flow efficiently. A programmable timer offers added convenience by allowing scheduled activation, often seen combined with a thermostat function.
An electric heater’s price correlates to its features. Models without thermostats are cheaper, providing only radiant heat. For better control and safety, a heater with a thermostat is advisable, ceasing function when desired warmth is met.
It’s difficult to assess a heater’s noise level in stores. While some brands indicate noise levels on packaging or literature, high-quality product listings online often contain this information—physical stores might not. Generally, baseboard and radiant heaters are the quietest as they don’t involve fan use.
Selecting an electric heater requires informed decision-making; although it might seem spur-of-the-moment, careful planning helps choose a heater that conserves energy and reduces electricity bills. Use all available resources to gather vital knowledge for making an intelligent purchase.
The design of an electric heater should complement the space it will warm. A significant factor in this choice is the aesthetic appeal. For instance, a tower heater, which rotates to distribute heat, might not enhance the room's look if placed centrally. In contrast, a wall-mounted stove heater blends in discreetly. Selecting the right design can be a creative and enjoyable process.
Air heaters are defined as electric heaters that provide heat for industrial and residential purposes by way of air circulation or a blower mechanism. Air heaters can be rectangular or barrel shaped, large in size, and portable, but other models of air heaters that vary in size and shape are also available.
Air heaters are designed by placing a stationary heating element within an enclosure. Air ducts periodically expose different sections of the heating element to circulating air by rotating alternately. While heating elements can vary, they are typically made of wires or coils. Wire heating elements are frequently used in industrial and commercial drying applications, often found in machines like kilns and surface treatment heaters.
Air heaters serve various purposes and come in diverse configurations with different heating elements. In homes, they are used daily to heat spaces, food, and water, while industries depend on electric air heaters to regulate temperatures for various processes. To ensure optimal efficiency and safety, it is crucial to evaluate the heating system and its intended application thoroughly.
Band heaters, also known as knuckle heaters or barrel heaters, are a variety of heating element that provides direct or radiant heating by clamping around nozzles, pipes, or cylinders. Band heaters are used primarily in metal and plastic forming processes such as extrusion, and are similar to strip heaters in terms of application and configuration. The range of temperature that band heaters provide can vary from 300 to 1400 degrees Fahrenheit. (approx. 149 to 760 degrees Celsius). Strip heaters can also be clamped or bolted in order to achieve the direct transfer of heat to either the air or a solid object.
Band heaters, along with other heating equipment, are essential for various industrial processes, particularly extrusion. This process requires melting materials and maintaining their plasticity for successful extrusion. Friction during extrusion generates heat, but band heaters supplement this by providing efficient, direct heat. They are especially effective in heating irregularly shaped areas where other heaters may struggle.
Cartridge heaters are small, cylindrical electric heaters used to provide localized or precision heat to materials and equipment parts in a variety of settings. Similar to immersion heaters, cartridge heaters are usually inserted into a material to heat the surrounding area; unlike immersion heaters, which are usually submerged in water or other liquids, cartridge heaters are inserted into small holes drilled in metal materials and parts that require internal heat. While capable of providing localized high temperature heating, cartridge heaters can also radiate heat throughout the interior of a material or product.
Cartridge heaters provide localized, interior heating for specific components in various machinery across industries such as packaging, die cutting, mold forming, hot stamping, labeling, sealing, printing, fluid heating, and food service. Internal cartridge heaters are commonly used in hot plates, platens, semiconductors, shrink wrap machines, and labeling equipment. They are particularly vital in plastic and rubber forming processes, where they aid in material plasticization alongside other localized heating systems like strip heaters.
Ceramic heaters are among the most widely used electric heater varieties. Ceramic heaters are used as heating elements in a variety of configurations to provide conductive and radiant heat. Conductive ceramic heaters can be combined with aluminum nitride or other compounds to form warming plates or bonding instruments for medical devices and semiconductor applications. Stand-alone ceramic heating elements may be packed with magnesium oxide and terminated with lead or copper wires for use in a number of industrial applications.
Ceramic space heaters feature ceramic-insulated heating elements along with aluminum baffles and fans to deliver safe and energy-efficient radiant heat. These heaters are commonly used in rooms as ceramic room heaters. Additionally, other electric heaters, such as ceramic strip heaters and ceramic band heaters, also utilize ceramic insulation to transfer heat effectively.
Ceramic-insulated heating coils offer enhanced safety compared to uninsulated coils, particularly in industrial and consumer ovens. The insulation shields the coils from exposure to dripping grease or other materials, maintaining their effectiveness and significantly lowering the risk of fire.
Coil heaters are electric heaters that generate heat through the use of heating coils. A heating coil is a device that converts electricity to heat. Heating coils are among the most widely used heat generation materials in existence. Across industry, commerce and in the context of consumer products, heating coils are used to generate heat in buildings, equipment, small appliances and in other applications.
These heaters can be customized to various sizes and shapes, including round, coiled, and spiral forms, ideal for high-temperature needs in confined spaces. Star wound coils are inserted into pipes and ducts to induce turbulent flow in air or liquids. They find applications across industries such as heating, plastic manufacturing, food processing, textiles, and paper production.
There are a few different styles of drum heaters out there in order to accommodate a wide range of applications and industries. While the designs may be different, drum heaters are all manufactured in a way that allows them to increase the overall temperature of a liquid that is being stored within a container, or 55 gallon drum. The reason why the word container is thrown around is that some drum heaters have the ability to heat multiple containers instead of being restricted to one drum at a time. The type of drum heater that you require is all based on the individual needs and requirements that are present in your specific application. Whether you require a large drum heater, such as a drum oven, or a mobile single drum heater, finding the right drum heater manufacturer can save you time and money.
A duct heater is a heavy duty modular unit installed in the ventilating ductwork of commercial, residential and institutional HVAC systems, although smaller "duct" heating elements are used in the forced air heating systems of vehicles. Duct heaters can be complementary to a central heating system that utilizes forced air heating, also known as forced circulation heating or convection heating, where air is the medium that transfers heat. Fans and blowers are integral to the transfer of heat; their motion conveys the air through the duct heater.
Duct heaters integrate with existing central forced-air heating systems to preheat either fresh or returned air. The central air handler filters the air, reheats it, and circulates it through the ductwork. This conditioned air is distributed throughout the building and eventually returned to the central air handling unit (AHU). While most electric heater manufacturers design duct heaters in rectangular or square boxes, they can also create rounded models to fit specific sheet metal ductwork configurations.
Flexible heaters are great for a wide range of applications as they are able to fit into tight spaces and provide heat to areas or products that other traditional methods may not be able to reach. Flexible heaters are commonly found in applications such as air heating in baking ovens, surface heating, cabinet warming and a number of different other industrial applications. A majority of flexible heaters tend to be made from plastics or metals; obviously this all depends on the requirements of the application and the temperature range that they will be exposed to during the process. Other materials that are commonly used to manufacture flexible heaters include rubber molding, rope, certain adhesives, and polyimide films. These flexible heaters are manufactured in a way that will allow them to conform to a surface which requires heating in a number of different applications.
Foil heaters are used in many industries and they can be found in products like car battery warmers, cabinets, defrost applications, heat exchangers, laboratory equipment, incubators, ceiling panels, and wall panels. Most foil heaters are etched using an automated machine. The etching in the foil helps to distribute the heat evenly when the power source is turned on by putting more of the surface in contact with the device being heated. The computer-designed etched foil is sometimes manufactured with a laminated coating on either side to insulate it.
One major advantage of foil heaters is their rapid heating capability, thanks to the highly conductive and thin foil material. These thin foil sheets can be seamlessly incorporated into products with limited space. Foil heaters utilize wider elements, which can be placed closer together. This allows for multiple elements to be arranged side by side, generating more heat in a compact area.
Infrared heating works by using electromagnetic waves to transfer heat directly to objects or materials. An infrared heater heats its panels until they emit infrared radiation, similar to the sun's rays. This radiant heat travels directly to solid objects, effectively warming them without altering the surrounding air temperature.
An infrared heater transfers heat through the emission, reflection, and absorption of electromagnetic waves. Its key components include a heating system and a reflector. The heating system converts electrical or chemical energy into thermal energy, while the reflector directs this thermal energy toward surrounding objects. The efficiency of the heater largely depends on the reflector. Common reflector materials are aluminum, stainless steel, ceramics, and quartz, with some high-performance models using gold or rubies to enhance reflectivity and focus heat more effectively.
Infrared heaters are highly efficient and energy-saving, making them perfect for industrial applications like drying coatings, welding, and embossing or laminating. There are three main types of infrared heaters: quartz, ceramic, and metal sheathing. These heaters can rapidly achieve temperatures between 1300°F and 1600°F (704°C to 871°C). Among them, quartz heaters reach the highest temperatures, while ceramic heaters offer the most cost-effective solution.
Forced air heaters generate heat by using a fuel source or electricity to warm a heat exchanger. Air passes over the heated exchanger, absorbs the warmth, and is then circulated through ductwork by a fan or blower. Their versatility makes them a popular choice for many applications and processes.
The core element of a forced air heater is the heat exchanger, which can be one of three types: shell and tube, plate, or air-cooled. Shell and tube heat exchangers feature multiple small tubes within a cylindrical shell, expanding and contracting with temperature changes. Plate heat exchangers consist of a series of stacked plates, either brazed or gasketed, depending on the application and fuel type. Air-cooled heat exchangers are compact and portable, providing both heating and cooling.
The next crucial component of a forced air heater is the blower or fan, which draws in air to be heated and then circulates it throughout the space. In an electric forced air heater, electricity heats a heating element that transfers warmth to the heat exchanger. Once the air is heated, the blower expels it into the room. The direction and distribution of the heated air depend on the specific type and design of the forced air heater.
Industrial forced air heaters come in various sizes, ranging from models that can heat large buildings to compact units designed for smaller sections. Their flexibility and mobility contribute to their widespread popularity. Furthermore, among the different heating methods, forced air heaters are often the most economical and cost-effective option.
Electric fan heaters operate using resistive or ohmic heating, also known as the Joule-Thomson effect. In this process, electric current flows through a resistant material, converting electrical energy into heat. This heat is produced on a microscale as conduction electrons transfer energy to conductor atoms through collisions. A fan then disperses the generated heat into the surrounding environment.
A fan heater works similarly to a forced air heater but utilizes electricity-generated heat differently. Like a forced air heater, it draws air from the surroundings, blows it over a heating element to warm it, and then releases the heated air into a room, enclosure, or portable office.
Electric fan heaters feature a straightforward design that simplifies their use and installation. They generate heat quickly and efficiently, converting a minimal amount of electricity into warmth with minimal waste. However, due to their high operating costs, electric fan heaters are typically used only for short periods.
Modern fan heaters now feature advanced power settings and thermostats that automatically turn off the fan once the desired temperature is achieved. Their portability makes electric fan heaters perfect for factories and manufacturing environments where precise, targeted heat is essential for various processes.
Strip heaters are direct contact heaters designed to be bolted, clamped, or secured onto the surface of an object for efficient heating. Their compact size allows them to be used individually or in arrays based on application requirements. They feature a flat, straight design akin to a ruler, with added fins for heating the surrounding air.
A strip heater operates by converting electrical energy into thermal energy through the Joule-Thomson effect. Its design facilitates increased collisions between electrons and atomic ions on the surface, resulting in vibrations that generate heat.
Strip heaters consist of a heating element, sheath or sleeve, and mounting hardware. When used for radiant heating, they include additional fins. Their flexibility allows for bolting or attaching them to walls, pipes, and other surfaces to distribute heat over extensive areas. Typically used indoors, strip heaters are commonly found in baking ovens and vacuum dehydration systems. In colder climates, they are also employed to heat equipment and provide moisture protection.
Strip heaters are popular for their straightforward design, affordability, and portability. They feature insulation made of mica or ceramic and outer shells constructed from steel, stainless steel, or nickel alloys. These heaters can achieve temperatures ranging from 700°F to 1400°F (371°C to 760°C).
Cable heaters consist of narrow-diameter cables that can be bent, shaped, and configured to suit any heating requirement or application. These heating cables, also known as trace cables, heat cables, or heater cables, generate heat by passing an electric current through them. They come in various types, each designed to achieve specific temperature ranges for diverse applications and processes.
The heating cable looks similar to standard wiring but is stiffer due to its protective housing. This design allows the heating cable to be cut and trimmed to various lengths, enabling it to be shaped to fit the specific requirements of different applications.
There are two main types of heating cables: self-regulating (or self-limiting) and constant wattage. Self-regulating heating cables are designed to prevent overheating by maintaining a set temperature limit, which avoids burning out. These cables typically operate at lower temperatures, reaching up to 250°F (121°C).
Constant wattage heating cables do not have a fixed temperature and require a control mechanism for operation. They can achieve temperatures up to 500°F (260°C) and operate across voltages from 120 V to 480 V. Additionally, these cables are available in various types, each tailored to specific applications.
Convection heaters, or convector heaters, are fan-free units that use natural convection to distribute heat. By heating the air inside, these heaters create a difference in density, causing the warm air to rise and push cooler air into the unit. This method of heat transfer is quieter and avoids circulating dust and pollutants, as it lacks fans or blowers.
A convection heater consists of two main components: the heating element and the fins. Convection heating works by converting electrical energy into heat through resistance wires in the heating element. This element features metal sheaths that enclose spiral-wound resistance wires within an insulating powder, like magnesium oxide, all encased in a metal sheath.
The fins of a convection heater function like a chimney, enhancing heat transfer by directing airflow over the heating element and its surface to warm the incoming air. The design of these fins varies based on the heater's intended use. Standard convection heaters typically feature aluminum fins, while heavy-duty models, designed for high-demand applications, use steel fins that are brazed for added durability and explosion resistance.
Convection heaters are equipped with an over-temperature sensing device positioned near the heating element. This device halts the flow of electricity if temperatures exceed safe levels, typically due to a blocked air inlet causing excessive heat buildup.
Electrical cabinets need to maintain a stable temperature to ensure the proper functioning of electrical components. Enclosure heaters help regulate this temperature by warming the air inside the enclosure, reducing humidity, and preventing electronic components from freezing.
Enclosure heaters come in different types based on the size of the enclosure. Small enclosures typically use small ceramic heaters, while larger ones may require convection or forced air heaters. These heaters are designed to prevent condensation and ensure even heat distribution. Moisture buildup inside enclosures can lead to corrosion and rust, potentially causing failure in critical electronic components like circuit breakers, relays, busbars, circuit boards, and transformers.
Enclosures can utilize a variety of heaters, including fan heaters, convection heaters, surface or strip heaters, cartridge heaters, flexible heaters, and tubular heaters. When selecting an enclosure heater, the primary consideration is the cabinet's dimensions—height, width, and depth—as these define the cabinet's volume. The second factor is the density of the enclosed instruments, which impacts the overall volume of the cabinet.
The next crucial step in selecting a heater for an enclosure involves considering the cabinet's location. This includes factors like exposure to harsh weather, risk of freezing, and the availability of energy sources. Additionally, enclosures on ships, planes, rockets, and satellites must be specially engineered to meet their unique environmental conditions.
Kickspace heaters are installed at floor level, typically near the bottom of cabinets or cupboards. These compact, space-saving units are often hidden along baseboards and are commonly known as toe kick heaters due to their placement. They work by drawing cool air over electrical coils, which heat the air and then release it back into the room.
Kickspace heaters are compact enough to fit into almost any space, overcoming layout or structural challenges. Their discreet design makes them a popular choice for heating, as they blend seamlessly into the surroundings without disrupting a room's ambiance. This allows for greater design flexibility in interior spaces.
Kickspace heaters are designed for heating compact or hard-to-reach spaces like small rooms, powder rooms, dressing rooms, and kitchens. Due to their size, they are not suitable for large areas. Each unit operates independently with its own controls, allowing it to function without connection to the main heating system. This setup enables precise temperature control for individual rooms or areas without affecting the main system.
Mica heaters, also known as micathermic heaters, are highly efficient due to their dual-function heating method, combining convection and radiant heat. They feature heating elements similar to convection heaters but are covered with mica panels. Mica is renowned for its ability to emit electromagnetic rays, enhancing the heater's effectiveness.
Mica is a preferred material for heating applications because it can quickly achieve temperatures up to 1112°F (600°C). Its thin sheets contribute to low thermal mass and very fast heating times. Mica heaters are constructed with etched foil heating elements sandwiched between high-temperature mica layers, ensuring superior heat transfer. To maximize efficiency, mica heaters are secured between rigid plates to prevent layer separation.
Mica possesses key qualities such as heat resistance, electrical conductivity, and chemical stability, which collectively ensure a safe and efficient heat source. Its thermal stability prevents fires and malfunctions, allowing mica heaters to be installed without the risk of burning or scorching surfaces.
Mica heaters' exceptional heating efficiency stems from their unique blend of convection and radiation. Unlike traditional infrared and convection heaters, which have limitations on the areas they can warm, mica heaters operate silently without the need for blowers or fans, effectively heating any size space.
Unlike traditional heating methods that generate heat through plates or tubes, heat pumps absorb heat energy from the outside air. Similar to an air conditioner, a heat pump manages unwanted temperatures by transferring heat. However, while an air conditioner only removes warm or hot air, a heat pump can both extract cold air and add heat, adjusting its function based on the season and settings.
A heat pump draws heat from the ambient air, which circulates over a heat exchanger's surface. This heat causes the refrigerant to evaporate into a gas. The gas is then compressed, increasing its pressure and temperature. The heated gas flows over an internal heat exchanger, warming the air that is distributed throughout the building.
Heat pumps are highly efficient, extracting more heat energy from the environment than the energy they consume. They produce two to three times more heat than the electricity they use. Hybrid heat pumps work with traditional heating systems, adjusting their operation based on the outside temperature to optimize heating. Unlike other heating methods, heat pumps generate minimal emissions due to their exceptional efficiency.
