The infrared heaters are in trend. But, are they really worth it or just a waste of money?

Winters often turn out to be the most uncomfortable days of the whole year. Especially at night, the outside temperature went below the tolerable range and now you’ve to spend the whole night with unpleasant periods of sleep.

Well, infrared heaters are something new to the market. But the benefits they provide you with are non-negotiable. With them you can easily expect to save a tonne of money on electric bills, they’re human friendly and don’t cost much. 

But, to make a firm decision, it’s important to know at least a bit about the technology of the product. Given below is everything you’ll need to know about infrared heating and heaters. Moreover, you’ll know why you should consider them in the first place.

What Is Infrared Heating?

The idea of infrared heating to man is a recent thing, but it’s billions of years old to nature. And our Sun is the most evident proof to the above statement. Wondering How?

Our planet receives varieties of energy in the form of waves. Some of these famous electromagnetic waves are Visible light, UV rays, and infrared rays. Nevertheless, every type of ray has some impact on Earth, some of them are helpful to us while some are harmful as well.

Fortunately, the infrared rays act as the friend of mother nature and are responsible for the heat we experience. These rays are pretty much straightforward due to their long wavelength. They directly heat the objects (trees, animals,  houses in this case) without wasting much energy in the medium. 

Ever enjoyed sunbath during warm sunny days? You started feeling the warmth in no time, isn’t it? Another valid example of infrared heating is the heat our body produces. This phenomenon is widely known as heat radiation also.

The above phenomenon is simple yet effective for us. This is the main reason why we’ve started using infrared heating lately. And the infrared heater is among them. 

The Pros of An Infrared Heater

There’s no doubt that infrared heaters have an upper hand over other conventional heaters. Some of them are not primary while others will uplift your lifestyle. Let us have a deeper look at it. 

1. Instant Heat

The infrared heaters quickly start heating the object in front of it. The reason behind its quick-heating process is it doesn’t use convection like other general heaters. 

These conventional heaters start heating the nearby air as the first process. And as a warm air zone, we experience heat. This method of heating includes tons of energy and time to get the work done.

2. Zero Noise

Another intriguing feature of infrared heaters is that they produce zero noise. The whole credit goes to their working mechanism. There’s no need for a fan to spread the warm air all over the room. Instead, these heaters use light energy that doesn’t require any rotation to generate heat. 

This feature becomes more vital to have distraction-free sleep. You’ll never have to listen to the buzzing sound in exchange for comfortable warmth.

3. Natural Heating

As discussed earlier, the sunlight we receive is also a part of infrared heating. This implies that using an infrared heater provides us with the same benefits as receiving sunlight. Besides, there’s no need to worry about harmful UV rays as well.

Getting heat similar to the sun doesn’t only ensure comfortable heat but also ensures other biological benefits. This heat will help your body in blood circulation, to breathe easily, without inhaling many pollutants.

4. Save Bills

Even the most top-notch ceramic heaters are no match to the infrared heaters in terms of saving both energy and money. The single reason for not using convection for heating provides a great benefit to the infrared types. 

In general, conventional heaters use up to 40 Watts of electricity to heat every cubic metre. The number itself seems much higher for savings oriented families. But don’t worry at all, here’s a piece of good news.

You’ll be amazed to know that infrared heaters only consume 25 Watts of electricity per cubic metre. Thus, you start getting 35% savings right from the beginning.

Apart from the savings in electric bills, these heaters don’t demand much care as well. You can easily expect a high life expectancy of 20,000 hours to 60,000 working hours. On the other hand, ceramic heaters don’t last more than 2 years. 

The Cons of An Infrared Heater

By looking at the list of the advantages of infrared heaters over conventional ones, the winner has already been declared. However, as every coin has two faces, an infrared heater also comes with several downsides. Let us discuss and know whether these will bother you or not.

1. No Power No Heat

The most visible downside of this heater is you’ll stop getting a heat, the moment you’ll switch it. As there’s no convection, the heat doesn’t get trapped in the air. 

However, the objects nearby you will still radiate some heat to the environment. But, there would be no match to the direct infrared heating.

2. Possibility of health issues

Don’t freak out, if you don’t face any serious issue roaming under the sun. The infrared heater is a minor replica of the sun. And it can lead to allergies or skin disorders if you face the same issue when expose to direct sunlight.

How Does Infrared Heater Works?

The credit for discovering infrared rays goes to the German astronomer, Sir William Herschel. He experimented back in the year 1800 to observe the magnitude of different waves with different wavelengths. 

He also came up with several interesting facts about these infrared rays. And we’ll discuss it in a short while. But, now let us continue towards the working of the infrared heaters.

In general, infrared heaters are not just for domestic use, they’re widely adopted in factories and greenhouses.  However, all of them work on basic principles. We’ll stick to the home heaters only. 

The infrared heaters used in the room are fueled by electricity and then turned into radiant heat. In the next process, these waves are scattered all around the room, just like an LED light does to the darkroom. As a result, the objects including us start getting warm within a few seconds. 

Here’s the real benefit. The infrared rays are just opposite to the harmful UV rays which are of small wavelengths. Thus, no matter how much we consume infrared, it’s not going to harm our bodies or any other objects. Indeed, you’ll feel more heat with the increased time and intensity of the heater.

Moreover, this heat is the most ideal heat for all the warm blood species. This is what we’re meant for. For using the room heater for the utmost comfort you should maintain the room temperature between 16C to 26C. This is the sweet spot temperature where even elders of your house will have no problem staying in. 

Thanks to the straightforward nature of the infrared rays, maintaining such a range is now easier and faster. The heater will quickly make you warm without wasting any energy in the medium.

Aim for Far Infrared

The experiment conducted by Sir William Herschel brought several discoveries to the science world. He observed the high radiant waves as infrared rays but there was more to it. 

He found that despite being a high wavelength ray, infrared includes the whole spectrum of radiant heat in itself. This range includes a high-intensity heat of  2600 degrees being the highest and 20 degrees is on the lower side).

These categories are-

  • Short Wave or Near Infrared (IR-A)
  • Middle Wave or Medium Infrared (IR-B)
  • Long Wave or Far Infrared (IR-C)

We shall get into these categories to compare the quality of an ideal infrared heater.

Near-Infrared or IR-A

Near-Infrared or IR-A aren’t friendly to any living organism. They’re too direct and intensely hot. Our body automatically goes to the defensive mechanism and attempts to not absorb this heat as much as possible. 

The rays in the spectrum are denoted by bright orange and red colours for indicating high-intensity heat. Many hot lamps and patio heaters tend to heat the environment by emitting short waves. Thus, you’ll experience discomforting heat and a suffocating environment.

Medium Infrared or IR-B

As the name suggests, the Medium Infrared or IR-B lies just behind the short waves. Their wavelength varies from 1.5 microns to 3 microns and is denoted with dark red colour in the spectrum. 

The Middle wave tends to behave friendly with human beings. However, they aren’t the best fit but absorbing them wouldn’t cause much harm too. These waves are favourable for public areas, saunas, and factory uses (mostly in drying processes). 

Far infrared or IR-C

Far infrared/ IR-C are the most ideal for every living organism. Their wavelength varies from 3 microns to 1000micros. And the heat emitted by these waves is of low intensity as compared to the other categories.

Fortunately, this temperature range works just fine for us. It doesn’t only provides comfortable warmth but also helps the body in various ways. 

A quality infrared heater should come with mostly Long-wave infrared rays.

Conclusion

An infrared heater is a wonder in the heater space. Its innovative yet powerful technique of providing heat is slowly capturing the market majority. The only baseline here is you shouldn’t be sensitive to the sunlight. Besides this issue, you’ll surely have a satisfying experience with them.

But hold on, don’t go easy on the final process. You still need to go with the most ideal infrared heaters in the market.
