5 Laws That Can Help The Electric Heater Industry
What You Need to Know About an Electric Heater
Electric heaters are an excellent way to provide a quick blast of warmth when you need it. They are usually designed for a certain size of room and come with features like thermostats, overheat switches and timers.
An electric heater converts electrical energy into heat through joule heating. The heating element makes use of nichrome wire, which is supported by ceramic insulators.
Resistor
The resistor is an electrical element that blocks the flow of current in a circuit by cutting down its voltage and absorption of some of it as heat. It converts electrical energy into thermal that is discarded in a fraction of one watt. This is a standard process that is found in electric light bulbs and heating elements.
The thickness, material, and other properties of the resistor determine its resistance. The higher the resistance of the resistor the more power will be absorbed. This is because higher currents lead to more electrons inside the resistor and more electrons lead to more collisions between them. The higher the temperature, the more collisions will occur.
Resistors have a maximum power rating they are able to safely dissipate. This usually ranges between 1/8W (0.125W), and 1W. Resistors with a higher power rating can be distinguished by their larger packaging. You can determine the power rating by looking at the packaging or comparing it with other resistors of known power ratings.
Electric heaters are a special kind of power resistor that is designed to convert electricity into heat. They can generate convective or radiant heating by emitting infrared radiations. They are typically used with fans to improve the efficiency of heating.
If the maximum power rating of a resistor is exceeded the resistor will heat up and can damage nearby components. In extreme cases, it may even get to a point of self-ignition and result in an ignition. To prevent this from happening, it is recommended that a resistor is installed to limit the current.
Heater resistors have a color code which indicates their value as well as other data like manufacturing accuracy and temperature coefficient. For instance, a 6-banded resistor has the first five bands that will tell you its digits. Then the sixth band informs you of its multiplier and tolerance. There are fireplace electric heaters can use to calculate the value for your own resistor.
Coil
Electric heating coils are at the center of any device powered by electricity that uses heat to warm objects or liquids. These heaters use the process known as conduction to convert electricity into heat. They can be shaped in a variety of forms based on their application. Heating coils made of electric are capable of generating a significant amount of heat in a short time, making them suitable for applications that require fast temperature changes or high levels of thermal efficiency.
The core of an electric heating coil is an intricately twisted structure made composed of wires made from metal. This structure is tightly packed, allowing the most wires to be confined within the smallest space, thereby increasing conductivity. The coil is then insulated with various materials, depending on the requirements of the specific application. For example the insulation of an electric heater used for liquid immersion could be made from a non-flammable substance like polyvinyl chloride (PVC), polyester, or polyimide, while a coil used for cryogenic applications is usually lined with molybdenum disilicide.
These materials aren't just resistant to corrosion and oxidation, but also provide protection against the elements. This makes them ideal for a variety of 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 alloys offer a great compromise between cost, corrosion resistance, and oxidation resistance.
Because the metals in the heating coil are subjected to corrosive and high-temperature environments, they must be protected from damage. This protection includes coatings and sealants, improved drainage and ventilation, regular maintenance and inspections. Moisture intrusion is another problem which needs to be addressed. It can cause damage to the heater's internal components, and shorten its life span.
Coils are also used in other devices, like ovens, water tanks and furnaces. They can be shaped into various shapes to suit the needs of the application and are usually printed on substrates such as aluminum 6061-T6, muscovite or phlogopite mica sheets, or conductive plastic. They can be coated with a wide range of materials to enhance their appearance and performance, including silver, gold and nickel.
Thermostat
You probably don't think about it but your thermostat is an important element of your home's comfort system. The primary purpose of the thermostat is to turn on and off the heater, so it can maintain the temperature you want to maintain. It also allows you to adjust the temperature based on your routine. This is great for those with an unpredictable schedule.
The most commonly used type of thermostat is the electronic, digital variety which you can program with a smartphone app or computer interface. Many newer models even have a learning capability that automatically adjusts to your personal preferences, so you'll never have to worry about when you should be at home for dinner.
In the older thermostats that did not have digital technology the electrical circuit was controlled by a bi-metal coil or metal strip that would expand or contract based on the temperature. When the strip expanded or contracted it was tipped by a mercury switch, activating the relay which switched on the heating. Then, as the strip cools, it bent and snapped back into its original position, which turned off the heating.
Modern electronic thermostats are more precise than electromechanical ones, which use an electronic temperature sensor and a small relay. However, it's still easy to understand the mechanics of an electromechanical thermostat by examining its components.
One of the main components is a thermometer coil that has a piece of mercury within it. When you move the lever on the thermostat upwards or down, it rotates the coil and tips the mercury switch in one direction or the other. If the mercury switch is tipped to the left, it will activate a relay and turn on the heater.
As the room gets heated the mercury turns right and breaks the circuit. The heater then shuts down. As the room cools down the mercury reverts to its initial position. The heater then switches on. If you keep changing the temperature of your electric thermostat, it could need to work harder to keep up with the changes. This can result in it using more energy than it needs to.
Timer
A wall heater timer is a useful device that helps you schedule your lighting and heating. It has a built in clock which will automatically turn on and off your heaters or lights at the time you set. It also helps you save money on your energy bills by avoiding excessive use.
They are typically employed in homes however, they can also be found at commercial and industrial facilities. They offer convenience, energy efficiency and security by controlling the time that electric circuits are turned off and on. They can be connected to appliances such as water pumps, lights, and ovens. They are a great choice for those who wish to control their electrical appliances with out the need for a complicated programmer or a computer.
The plug of a timer switch onto an extension cord or outlet allows you to set it. Plug in the appliance you want to control. Depending on the model you can plug in multiple devices at once. Some models have a socket located in the middle of the timer whereas others have the socket either on the side or beneath it. You can choose between a variety plug-in switches, including those that can be controlled with a smartphone or tablet.
The majority of mechanical timers come with a dial that has hour and half-hour marks. You can also use the teeth to set an "ON" and "OFF" time. There are also models with multiple sets, which allow you to change the on and off times for different days of the week. It's important to remember that mechanical timers may not work properly, especially if the internal clock gets a bit off. If your timer isn't turning on or off when it is supposed to be, look over the wiring for any problems and ensure that all pins are properly inserted. If you're still unable to get it to function, it's best to contact a professional for assistance. Alternately, you can replace the timer with a fresh one. It's important to keep the timer in a safe area, where it will not be easily disturbed by children or pets.
