How Does An Infrared Space Heater Work?

No comments

You might have learnt about infrared radiations in your science subject. So, you might remember that these rays are invisible as they don’t come in our spectrum range. This is the summary of infrared heaters. The reason we feel warm from these heaters is that our clothes and skin absorb such heat. It’s the same feeling when we go out in the sun. Our body absorbs sunlight, and we feel warm, and when we sit in the shade, the light never reaches us.

Infrared space heaters are an excellent device to keep the desired space warm. Such heaters save a lot of energy while keeping the entire space warm and cozy. These heaters work well for family rooms, living spaces and insulated garages. So how do these heaters work? They convert electricity into radiant heat. Infrared rays are a part of the electromagnetic spectrum, and it gives the same warmth as that of the sun in winters. Infrared heating directly heats the objects present in the room, instead of heating air comes in between. The human body absorbs the wavelength of such radiations very easily.

 

This article will discuss everything about infrared heaters, right from their working to specifications and their eco-friendly nature.

 

Heat for which the human body is made

 

The human body is radiant. Our body’s comfort or discomfort depends upon the radiant heat loss or gain. This implies when our body absorbs heat, we feel the warmth, and when it radiates heat in the environment, we feel cold. For many of us, if the environment temperature is more than 26°C or less than 16°C, we feel discomfort as our body gains or losses excess heat. So, when the outdoor infrared heaters warm the walls, floor and ceilings of the room, we remain at the temperature between 17°C-22°C and hence our body never loses heat at such a temperature, and we feel comfortable. This is the infrared heating system; it builds up the ‘thermal mass’ to keep the temperature warm.

 

Let your room radiate the heat

The primary work of infrared heaters is to heat all the objects present in the room. Once done, these objects automatically retain that heat for some time, and the heater’s work lessens down after that. Other types of heaters are convection heaters which firstly heat the air and then transfer that heat to the objects of the building to heat the thermal mass. The main issue with such type of heating is hot air drifts up towards the ceiling (where no one wants heat) and escapes from there. Because of such drawbacks, people are now moving towards infrared heating as they are more efficient and energy-efficient.

 

The efficiency of infrared space heaters

As the convection heaters heat the air first, even the latest model of such heaters will consume around 40 watts per m3. But the infrared heaters never heat the air; hence no energy wastage and the total energy consumption is around 25 watt per m3. Hence you can save around 37% of electricity cost compared to traditional convection heaters or night storage heaters.

 

When to use infrared heaters?

These infrared heaters are much suitable for warehouses, garages, household purposes and airplane hangars. Such places always have large doors which are opened and closed frequently; infrared heaters prevent too much cooling of such areas efficiently. These heaters are often employed in production lines in factories. But these heaters are not ideal for cavernous and industrial areas, as instead of pumping only hot air, these heaters warm up the objects. These heaters are also useful in construction areas to make the paint dry. Whenever direct heat is in demand, infrared heaters can prove their efficiency.

You can also find the utility of these heaters in the local gym or spa, as day by day, these heaters are gaining popularity in many sectors. New technology in these heaters directs the heat on the objects to give the feeling of direct sunlight without UV radiations.

 

Infrared Specifications

It is difficult to give a generalized specification about all infrared heaters, as each type of heater has a different specification. These heaters are of three types powered by natural gas, propane or electricity. If you have opted for an electric one, you should check the Hz and volts your heater uses.

Other specifications or you can call infrared heater accessories include: filter controls, thermostat, weight, fan, wheels and color. The design also plays a pivotal role during heater selection; many heaters cover heating elements like copper, iron, brass, or steel.

 

Are infrared heaters eco-friendly?

It isn’t easy to stay green while heating your space. But these infrared heaters cause minimal impact to the environment as compared to traditional ones.

Hope you have gathered enough information about infrared heaters and its benefits in keeping you warm.
