Infrared Heater – Save on Your Energy Bill

Do you need an additional heater, to complement your central heating system? Sometimes it just doesn’t make sense to turn up the temperature in the entire house so you can warm up one room you are in. It is much better to use an additional heater. Infrared heater can be of great help. Find out what are the benefits of infrared heaters comparable to other heaters.

Infrared heater efficiency

Most heaters work by warming the air in the room. People in the room are warmed by the air. Not only this wastes energy on warming up the air, but also you don’t feel the benefits of the heater as soon as it is switched on. It might take several minutes for a room to warm up. Infrared heaters work differently. They don’t heat up the air it heats objects that are directly in its path. As a result people in the area are warmed directly by the heater and not by the air.

This principle makes infrared heaters very energy efficient. Another advantage is that you don’t have to turn the heater on half an hour or hour in advance to pre-heat the room. You feel the warmth immediately.

Types of infrared heaters

Here are the most popular types of infrared heaters:

– Metal-sheathed tubular heaters

– Quartz tubes

– Quartz lamps

– Gas fired catalytic

– Flat-faced panels

– Ceramic emitters

Often people are worried that infrared heaters are not safe. There is really no need to worry. Most modern infrared heaters have a protective sheath to cover the heating elements. The cover is usually made of metal such as aluminum, brass, copper, iron or stainless steel. Blowing curtains won’t become a fire hazard with an infrared heater. Most home models are pretty safe, but of course children shouldn’t be allowed to play with the heating unit.

Another advantage is that infrared heater doesn’t make the air in the room dry. The principle of its work is very similar to the way sun warms us on a bright day.

You can find indoor infrared heaters as well as outdoor and patio heaters. The source of fuel can be different, infrared heater can run off electricity, natural gas or propane.

More tips for efficient heating

Using an additional infrared heater can save you a great deal on your energy bill. But there is more you can do. First, check for drafts and boost the insulation. At the beginning of winter, make sure that window caulking and storm windows are in good shape. You should also check thermostats and install timers for your central heating.

Electric Infrared Heaters

Infrared light and Infrared technology have probably been a part of science studies at school. They may have been alien then, but today we see and hear about products with infrared technology, many of them in everyday life. But frankly, none of us may have applied the little knowledge we have about it to really understand light spectrums and wavelengths.

We know, of course, that infrared light is beyond the spectrum of light elements that we can see but the heat generated by the light is what we can feel. Take the example of sunlight; when we are directly under the sun the sun’s rays that emit light also emit heat which is absorbed by our skin and the clothing we wear unlike in the shade when the sun’s rays cannot reach you directly.

An infrared heater is scientifically described as the ‘body with a higher temperature that uses electromagnetic radiation to transfer energy to another body with low temperature. There is no medium or contact mode needed for the transfer of energy; infrared heaters can be functional in a vacuum.


Classification of infrared heaters is done by the wavelengths they emit.

  • Near infrared (NIR) or short wave – operate at temperatures above 1800°C
  • Medium infrared or Carbon infrared ( CIR ) – operate at temperatures around 1000°C
  • Far infrared (FIR) – typically in the low temperature ranges, use low watt ceramic plates for emission


Infrared heaters are of several kinds – while some direct infrared light into a space or room to create heat when it reaches an object and some other infrared heaters emit heat on a 3-part action – infrared light bulbs, good metal conductor like copper for a heat exchanger and a fan to blow air on the exchanger to create heat.

There are also variations in the material used for construction of infrared heaters and in the fuel source – ceramic is the most common material while fuel can be electricity, natural gas or propane.

The important thing to note about it is that they all have certain specifications and can be used only in specific situations.

Electric infrared heaters

Tungsten wire is the commonly used filament material for electric infrared heaters; the wire is coiled so that it provides more surface area. Other alternatives for tungsten wire in low-temperature heat conduction are aluminium, carbon, chromium or alloys of iron. Carbon filaments spread heat much more quickly than other filaments but production is a fickle process.


· Better looks, more efficiency

· Easier to operate and maintain; no repairs of ignition components, burners or valves as compared to gas heaters

· Produce no odours, sound or toxic emissions

· Offer better mounting and installation options

· Economical and cost saving

Technical Aspects Related to Infrared Heaters

There are a lot of misunderstandings over the functioning for infrared heaters. For a better understanding, the working of infrared heaters is explained both in terms of practical understanding as well as technical understanding.

Technical Working of Heaters

Coil filament used in heaters is often made of tungsten or carbon or iron alloy. Light energy is transferred (or reflected towards a conducting surface) to the concerned object through a fan for convection heating. When the wavelength is closely matched towards the absorption spectrum of the concerned target, infrared heaters showcase the best efficiency possible.

Practical Working of Heaters

To explain in a layman’s language, light energy is directed towards the desired object or an area for heating. The target is heated as it absorbs the heat energy. In simpler terms, heating is done via infrared light.

Commercial Uses of Heaters

Infrared heaters are generally classified in terms of the wavelength of light that gets emitted by the concerned element.

Short wave type heaters are capable of reaching high temperatures hence they are suitable for commercial processes while long wave infrared are mostly used for residential purposes and also in small offices.

Apart from the standard uses of infrared, they are also used in

• Warehouses
• Construction sites
• Aviation hangar heating
• For drying paints
• For molding plastics
• Convection ovens
• Incubator heat lamps
• Dry saunas

Variations in Heaters

Infrared heaters utilize ceramic emitters, metal tubulars, quartz lamps and even quartz tubes for their working. Infrared heaters differ in terms of their wavelength, operating temperature, durability, efficiency and even cost

Benefits of Low Temperature Infrared Space Heaters

• They reduce the risk of accidental fires at your place.
• They help to preserve humidity which gets affected adversely due to electric heaters.
• They are devoid of harmful emission like carbon monoxide, carcinogens and other gases which are common to other type of heaters.
• They are worth every penny invested on them.
• They are easy to handle and even its maintenance is also not very complex.

All in all, they are considered the safest type of heaters and its use has seen a rise.
