Ever since the beginning of time, infrared heating has been used by people to heat objects. Our most well-known infrared heater is the sun, which can warm up even the coldest winter days. However, the surrounding air’s temperature does not necessarily determine whether you are warm or chilly. These heaters come in several shapes and sizes. Some people aim their infrared light directly into a room or place to heat anything it reaches.
The construction and fuel source of these heaters also differs. Some infrared heaters run on electricity, natural gas, or propane. These heaters have unique requirements and should only be used in specified conditions. Infrared heaters are far less harmful to the environment as compared to other heaters. If you want to know everything about infrared heaters, then keep on reading this article.
What is an Infrared Heater?
Infrared heaters are a type of heaters that emit radiant heat to warm the environment. Objects and surfaces first absorb this heat, then re-radiate back into the space it is supposed to heat. You can also experience this kind of warmth on sunny days when sunlight rushes in through your bedroom window and hits the surfaces of your room. This heat warms up your room slowly over time, and even when the sun has gone down, you can still feel the warmth. This is the same way infrared heaters work in. They radiate heat waves from the appliance’s surface, which are absorbed by the surface of your home and provide a constant source of warmth during the day and even at night.
Infrared does not heat the air; instead, it passes through it until it comes into direct touch with an object or a person. Infrared heaters are highly efficient because of that ‘A to B’ transfer or heat, which means less heat will be lost than ordinary convector heaters. These heaters are available in various shapes and sizes, ranging from electric patio heaters for outdoor heating places to slimline displays for everyday interiors. These heaters are an excellent way of keeping a room warm the whole day. This form of heating can enable you to save electricity while also providing adequate heat in your most-used areas. Open living spaces, enclosed garages, and living rooms are the best places for these heaters.
How Do Infrared Heaters Work?
Although every infrared heater radiates radiant heat, the working of every heater varies depending on whether it’s an outdoor or indoor heater.
Radiant panels, also known as infrared panels, operate by placing a length of resistive wire underneath the heater’s surface. Heat is conducted through the front panel’s surface and into the room when electric current flows through the wire. Many types of patio heaters, like wire-element and ceramic heaters, use the exact heating mechanism as radiant panels. Still, they require a much higher wattage to adjust for cooler outdoor temperatures.
Since infrared panels don’t come with moving parts and have a simple design, they have a significantly longer lifespan than other electrical heating systems. They release a type of infrared known as far-infrared. It is the lightest type of radiant heat and is also identical to our body heat.
Infrared Patio heaters
To balance the sense of being out in the cold, electric outdoor heaters also create a much stronger kind of radiant heat. On the other hand, infrared patio heaters also do this by using an infrared lamp. When turned on, these lamps have a carbon filament or tungsten present inside a quartz bulb. It is filled with halogen gas that helps produce high heat, providing quick warmth that you can enjoy even on a chilly day.
The lamp’s filaments heat up to the point where they emit a bright light, which is a nice little bonus feature as the night falls, offering additional light and a comfortable atmosphere while you’re sitting outside. These heaters use near-infrared, which is the hottest and most powerful form of radiant heat. Glowing patio heaters are also called quartz heaters and halogen heaters.
Infrared Heating Principle
Radiant heat travels through the air till the time it is touched by anything. This heat can be absorbed by almost everything; its radiant heat focuses on heating the interior space surface area instead of the air volume. As soon as the infrared is absorbed by a surface, such as the ceiling or walls, it is re-radiated back into the room, producing a 360° source of heat. Since infrared heats deep into the material of the building, it takes far longer for the room to heat up at first. However, once the room is heated, it stays heated for a long time. This is because infrared heaters heat the room evenly from top to bottom.
This enables infrared system users to lower their temperature by a few degrees while maintaining the exact level of warmth and pleasure as if they were using a traditional heating system. Since infrared heat transfer is not dependent on on-air movement, that is why it does not get affected by draughts and does not disturb pet hair, dust, or other irritants. Setting the positioning of infrared heaters is an essential component of using them correctly. To give maximum warmth, these heaters need a line of sight. It means that they should preferably be positioned to high-occupancy parts of the room so their heat can be directed to the place that needs more warmth.
Infrared Heater Cost Estimator
Running expenses vary according to the variety of characteristics of the heater, such as its amount of structure, location, age, and insulation, as they do with any heating system. Although the cost varies, however, you can estimate probable operating expenses with only a few simple pieces of information. To make an estimate, what you need to know is:
- First, you will need your energy bill in pence per kilowatt-hour.
- Second, the wattage of the infrared heater used.
- The total number of hours per day that you plan on using your heating.
Infrared Heater Advantages
- Provide instant heat
With infrared technology, the wavelengths produce immediate warmth even in the coldest conditions. So whether passive or active, it swiftly dismisses the cold, resulting in a much more comfortable environment.
When compared to traditional space heaters, infrared heaters are incredibly silent. The absence of a fan is the cause for this benefit. Instead of emitting noise, they emit light energy, making them an ideal addition to your bedroom or another place where noise pollution may be an issue.
- It does not harm the indoor environment.
Although infrared heaters have some drawbacks, they do not impact enclosed spaces as other technologies.
While using an infrared heater to heat a room, you won’t notice a difference in humidity. There is also no change in the oxygen content. As a result, you won’t develop dry skin or inflamed sinuses like you might with conventional warmers.
- You get to experience natural sunlight.
Infrared heaters generate the same type of heat that you get from the sun daily. This means you may make use of many benefits of natural sunlight without having to worry about UV rays every day. As a result, you’ll have faster warming benefits, more excellent blood circulation, and significantly less dust floating around the room, which is primarily present in the rooms due to the fans used by most other heaters.
- It won’t pollute the air in your room.
Infrared heaters have additional environmental benefits in that they do not emit toxins into the air when in use. So when you use this technique, you’ll get zero carbon emissions and no hazardous consequences.
Infrared Heater Disadvantages
- Can be dangerous
As soon as an infrared heater’s coils start to transmit heat, they eventually become boiling. Therefore, to prevent a contact injury, maintain a distance from the unit.
- Emits light
While transmitting heat to your surroundings, infrared heaters always produce an orange color. Although the purpose of this shade is to persuade people to avoid handling the goods, it may have some negative consequences.
- The room becomes cold immediately when turned off.
When an infrared heater is turned on, it may start working right away, but it will stop emitting heat as soon as you turn it off.
Infrared Heaters FAQ
Are Infrared Heaters Safe?
The infrared heaters work the same way as the sun. Therefore, these heaters are safe; however, they can be dangerous when the coils become hot. That is why you must take precautions.
Do infrared heaters use a lot of electricity?
Compared to other electric heating types like portable radiant space heaters, these heaters are quite efficient and do not use much electricity.
