Infrared Vs. Radiant Heaters: What Is The Difference? 

Have you ever wondered what is the difference between an infrared heater and a radiant heater? How are they different? Or are they the same thing? If so, then how are these two the same thing? If you have these thoughts, then let me tell you, you are not alone. 

While researching for best infrared heaters, I often came across these two terms- infrared heater and radiant heater. Similar to you, I also had a lot of questions. But after enough research, now I know the mystery behind Infrared heater vs. radiant heater. 

I’m going to break down everything about the infrared heater and radiant heater for you in this article. But first, let’s answer the actual question. 

What is the difference between an infrared heater and a radiant heater?

There is literally no difference between infrared and radiant heaters. When the heater is providing heat using radiation, we call it a radiant heater. Infrared, on the other hand, is the type of radiation that the heater is using. I think we all are aware that infrared heaters heat objects instead of the air. Meaning, the heater radiates heat to provide warmth. So, all infrared heaters are radiant heaters and there is no difference between these two. 

How Infrared Heater And Radiant Heater Are The Same Thing 

Infrared heaters are often compared to the sun. How does the sun radiate warmth and light? Through rays. Sun rays differ from each other because of the wavelength. We all know what a UV ray is, right? Infrared is also a ray similar to UV rays. 

The infrared part actually provides warmth. Likewise, if you compare an infrared heater to the sun, then infrared heaters use infrared radiation to provide heat. I hope that made a lot of sense and it is clear that infrared heater and radiant heater have no difference. 

What are the advantages of using Infrared Radiant Heaters?

Infrared heaters are also known as the best space heaters. Here are the advantages of using infrared radiant heaters.

Energy efficient 

Traditional heaters heat the air of the room to warm it up. On the other hand, 

Infrared heaters, projects heat to the targeted object instead of the air. Thus, there is hardly any energy wasted. 

Low maintenance 

With infrared heaters, you don’t have to worry about maintenance. Since infrared heaters don’t have any moving objects, they are quite durable. Thus, no maintenance is needed. 


Portable heaters are honestly the best. Most infrared heaters are compact and you can carry them with you and just enjoy the warmth!


Let’s just admit that nobody wants a noisy heater. It just makes no sense that a heater is noisy. The noise of the heater mainly comes from the fan part and most infrared heaters use forced air. Thus, infrared heaters hardly make any noise. In fact, people use infrared heaters even in libraries. Such as the Dreo Space Heater 2022 Upgraded Version. It is widely used in libraries. 

Comfortable heat

Space heaters can mess up the humidity of the room, resulting in dry and uncomfortable heat. Which is also not good for your skin. However, infrared heaters keep the oxygen level in the room. Thus, you can enjoy warm, comfortable heat. 

Dangers Of Infrared Radiant Heater 

Are infrared heaters safe? While infrared heaters are relatively safe to use. But the world isn’t just black or white. Even the Safest thing can be harmful sometimes if you are not careful. Infrared heaters are no exception. Even though infrared radiant heaters are not fatal, there might be a few dangers which I am going to address in the following sentences. 

Hot touch 

Some infrared heaters can be hot on the outside. Which can cause harm to your children or pets. So, make sure that you buy a space heater that has a cool touch exterior. Such as the AirNmore Comfort Deluxe Infrared Space Heater

Faulty wires

Infrared radiant heaters need electricity to operate. With electricity, you need to be extra careful. If there is anything wrong with the wires, it can be dangerous for your home. It doesn’t necessarily have to do anything with infrared heaters. Still, it is better to be safe than to be sorry! 

Eye protection 

Not gonna lie, it is fascinating to stare at infrared heaters but I am sorry to inform you that prolonged exposure to infrared waves can damage your eyes. So, from now on, avoid looking into the heating element.
