What You Need to Know About an Electric Heater Electric heaters can provide warmth quickly when needed. They are usually rated for a specific size room and include features like thermostats, overheat switches and timers. Electric heaters convert electrical energy into heat by the process of heating. The heating element is composed of nichrome wire and ceramic insulators. Resistor The resistor is a component that reduces the voltage and resorbs some of it in the form heat. It converts electrical energy into thermal energy, and uses only one watt. This process is found in a wide variety of electric light bulbs and heating components. The resistance in the resistor is determined by its thickness, material and other properties. The greater the resistance of the resistor the more energy will be lost. This is because higher resistances generate more electrons, which means more collisions. The higher the temperature, the more collisions take place. In general resistors have a maximum power rating that they are able to safely dissipate which is typically between 1/8W (0.125W) and 1W. Resistors that have a high power rating can be distinguished by their larger packaging. The power rating of a particular resistor can be determined by the package it comes in or by comparing its physical size to other resistors with a known power rating. Electric heaters are a specific type of power resistor made to convert electricity into heat. They produce convective heat through the circulation of air over the resistor, or radiant heat by emitting infrared radiation. They are usually employed in conjunction with fans to improve the efficiency of heating. If a resistor's maximum power rating is exceeded the resistor will become hot and may damage nearby components. In extreme situations the resistor can get to a point at which it self-ignites and causes a fire. To avoid this from happening, a limiting resistor is required to be incorporated into the circuit. Heater resistors are tagged with an identifier color that indicates its value and other information, such as manufacturing accuracy and temperature coefficient. A six-banded resistance, for instance, will have five bands that represent its digits and the sixth band will provide the multiplier and tolerance. There are a variety of online calculators that you could use to calculate the value of your own resistor. Coil Electric heating coils are the central component of any device powered by electricity that uses heat to warm liquids or objects. These heaters convert electricity to heat using a process called conduction, and can be formed into a variety of shapes based on the purpose for which they are used. Electric heating coils are also capable of producing a substantial amount of heat in a short time, making them suitable for applications that require quick temperature fluctuations or high levels of thermal efficiency. The core of an electric heating coil is a tightly wound system composed of metal wires. This structure is tightly packed, allowing for the most wires to be contained in the space, thereby increasing conductivity. The coil can be insulated in a variety of ways, based on its purpose. For example, the insulation of an electric heater used in liquid immersion can be constructed from a non-flammable substance like polyvinyl chloride (PVC), polyester, or polyimide, while a coil used in cryogenic applications is usually coated with molybdenum disilicide. In addition to protecting against the elements, these materials also offer resistance to corrosion and oxidation making them suitable for many industrial applications. Stainless steel is the most common element for a heater coil, but nickel-chrome and iron-chromium-aluminum alloys are also commonly used. These materials have a good balance of cost, oxidation resistance, and corrosion resistance. Metals in a heating element are exposed to high temperatures and harsh environments. They need to be protected. This includes coatings, sealants, better drainage and ventilation, and regular maintenance and inspections. electric stoves fires is another critical issue that needs to be dealt with since it can harm the internal components of a heater and reduce its life expectancy. Coils can also be used in other devices such as ovens or furnaces, as well water tanks. They can be formed into a variety of shapes to suit the needs of the application and are usually printed on substrates such as aluminum 6061-T6, muscovite, phlogopite mica sheets, or conductive plastic. They can be coated with a variety of substances to improve their appearance and performance, such as gold, silver and nickel. Thermostat While you might not think about it often the thermostat is a crucial component of your home's comfort system. The primary function of a thermostat is to switch on and off the heater, so that you can keep your desired temperature. It also has the ability to adjust the temperature according to your daily routine, which is a big benefit for those who have an unpredictable schedule. The most commonly used type of thermostat is the electronic digital type that you can program using a smartphone app or a computer interface. Certain models have the ability to learn and adapt to your needs. You'll never have to wonder when you should be home for dinner. In the old thermostats that weren't digital, the electrical circuit was controlled by bimetal coils or a metal band which would expand or shrink depending on the temperature. As the strip expanded and contracted it was tipped by a mercury switch and activated the relay, which turned on the heating. As the strip cooled it bent backwards and snapped out from its initial position. electric log burners shut off the heating. Modern electric thermostats are more precise than electromechanical ones, using the use of a temperature sensor and a tiny relay. However, it's still possible to understand the workings of an electromechanical thermostat by looking at its components. One of the key elements is a thermometer coil, which is made up of mercury within it. When you turn the thermostat lever upwards or downwards the coil spins and tilts the mercury switch in one direction or another. If the mercury switch is tilted to the left, it will energize the relay and then turn on the heater. As the room warms the mercury switches to the to the right and interrupts the circuit. The heater then shuts off. When the room cools down the mercury returns to its original position. The heater then switches on. If you continue to change the temperature on your electronic thermostat, it could require overtime to keep up with your ever-changing preferences, causing it to use up more energy than it needs to. Timer A wall heater timer is an efficient device that lets you plan your heating and lighting. Unlike traditional manual timers, it is equipped with a built-in timer that will automatically activate and deactivate your lights or heaters according to the time set. You can also save money on your energy bills by preventing excessive usage. They are mostly used in the home, but are also found in industrial and commercial facilities. They provide energy efficiency, convenience, and security by regulating when electric circuits are switched on and off. They can be used to control appliances like water pumps, lights and ovens. They are a great option for those who want to control their electrical appliances without the need for a sophisticated programming system or computer. You can create a timer switch by simply connecting it to an outlet or extension cord. Then, plug in the appliance you wish to control. Based on the model, you can also plug in several devices simultaneously. Some models have a socket at the center of the timer, while others have an outlet on the side or beneath it. There are various plug-in timer switches, including those that can be controlled with a smartphone or tablet. The majority of mechanical timers have a dial with hour and half-hour markers. They also have little teeth that you can pull outwards to set the “ON” time, and push inward to set the “OFF” time. There are models with multiple sets. This allows you to set the time for various days. It's important to note that mechanical timers do not always perform as they should, particularly if the internal clock gets a bit off. If your timer does not turn on or off when it should, check the wiring for any issues and ensure that all the pins are correctly inserted. If you can't fix it, it's best that you contact a professional. You may also try replacing the timer. It's important to keep the timer in a secure location, where it won't be easily disturbed by children or pets.
