What Is an Infrared Heater? How Does it Work?
An infrared heater is a heat source that transfers high heat through electromagnetic radiation. On the light spectrum, infrared operates just outside our visible range so we cannot see it. However, like the sun heating the Earth, infrared works by vibrating particles, causing them to oscillate and release energy. This release of energy transferred as heat energy, warms the surrounding area. It heats objects directly and can be operated without air.
With traditional heating, the air becomes dry and hot, but infrared heating works differently. No hot air is lost through ventilation, instead the particles themselves gain energy, which causes them to feel hot. This means the heat is locked within the objects that become heated, making it a far more energy efficient method of heating.
Types of Infrared Heaters
There are three types of infrared heaters; near, medium and far infrared. Near infrared heaters are generally used for cooking, welding and thermoforming as they heat up to temperatures around 2370F, operating in between 0.75 to 1.4 microns. The emitter is usually made of quartz, accompanied by reflective materials to direct the heat in a certain direction. These are not suitable for heating homes.
Medium infrared heaters, often used for glass blowing and smelting, produce temperatures between 930 and 1470F, operating at around 1.4-3 microns. Typically, they house a quartz emitter which consists of a heated wire in a quartz tube, although some versions have ceramic emitters. These are often used in industrial and public ‘space’ heating and are far safer than Tungsten or halogen.
Far infrared heaters emit temperatures below 212F, and unlike near and medium infrared, they don´t emit any visible red color. They operate in wavelengths of over 3 microns and tend to use nickel or carbon fibre heating elements. This is the type of infrareds used in domestic and commercial heaters.
Infrared Heaters vs. Conventional Heaters
Infrared heaters are far more efficient than traditional heating. The traditional ones heat air and blow it around using convection or simply pushing air with a fan. This is inefficient as hot air can escape through places that aren’t insulated or through gaps on the walls and windows. Heaters that run with infrared heat objects directly by vibrating the particles, reducing the loss of hot air.
Heat is more evenly distributed with an infrared heater as all objects in the room are heated directly. Traditional heating, however, needs to heat the air first, which makes it flow towards cold spaces, creating an uneven heat effect. Besides,, hot airl rises too, creating an uneven distribution lower down, resulting in cold pockets.
Because traditional heating warms the air, it causes water particles in it to evaporate. This is very dehumidifying, which can be hard on the skin, the eyes and the respiratory system. Infrared heating does not dry the air, avoiding such issues.
Moreover, traditional heating loses heat through poor insulation and cracks because of air loss, which means that these types of heaters need to work much harder to maintain the same heat levels. Often working between 180 and 220F, traditional heaters tend to use much more energy. In comparison, infrared heaters function between 100F and 130F and are able to maintain this heat consistently . This makes them far more energy efficient.
How to Choose an Infrared Heater
When choosing an infrared heater, there a few features you should look out for. Firstly, for the best energy efficiency, you want to look for an infrared heater with a thermostat that automatically regulates the temperature. It should turn off when the desired temperature is reached, preventing energy waste.
You need to consider the area you intend to heat. Choose a heater that has the capacity to handle the square footage of your room. As a rule of thumb, 34.1 BTU (British Thermal Units) will heat 1 square feet.
If you are looking for a portable heater, a heater with swiveling wheels is ideal. Equally, consider the weight as you don´t want it to be too heavy.
Quartz bulbs tend to have the longest life and are therefore the most durable types of infrared heaters. Equally, cool-to-touch exteriors are not only safer, but also tend to last longer. Heaters with shut-off safety features prevent the elements from blowing, increasing durability and lifespan.
You may also want to consider the style. Infrared fireplaces have a beautiful design but can be somewhat cumbersome if you want to move them around. Alternatively, you can find lightweight that less aesthetically stimulating heaters can be mounted on the wall or stored away if necessary.

Infrared heaters have become quite popular as highly efficient units. However, before buying one, you might be looking for more information regarding these. Find the answers to your questions below:
How Do Infrared Heaters Work?
The working of infrared heaters is much like that of the sun. These units give out infrared light that can’t be seen by the naked eye. People and objects in the room absorb the infrared light. Heaters also come with reflectors and coils to produce and direct the infrared light out from the unit.
Do Infrared Heaters Use a Lot of Electricity?
While infrared heat is as safe as conventional heat, infrared heaters require as much electricity as other kinds of heaters for producing it. You can find the electricity rating of a particular unit on its labels. Note that the rating can even go as high as 1500 watts.
Is an Infrared Heater Better Than Electric?
Compared to other heaters, including electric heaters, infrared heaters are more efficient. Unlike other heating appliances, these heaters don’t heat up the air. Instead, they give out infrared radiation to warm up the objects it touches.
Do Infrared Heaters Give Off Carbon Monoxide?
Usually, devices that burn any kind of fuel produce carbon monoxide. However, since infrared heaters do not burn any fuel, they don’t give off any carbon monoxide.
Can You Leave Infrared Heaters on Unattended?
