False conventional wisdom regarding the infrared heaters
As often the quick shortcuts lead to approximations and non-truth. With the support of some leading manufacturers, we would like to rectify some inaccurate and/or imprecise spread information… concerning the infrared heaters.
Does the warm feeling disappear once the heater is switched off? False.
““If the heater has a sufficient power and the range of its radiation is at least 4 m and the heater is well placed within the room (to reach all areas), then, even with the heater being switched off, the heat stored in the structure will be redistributed in the room.““

Do we have to be in front of the infrared heater to feel the heat? False
“An infrared radiant heater worthy of its name, has a sufficient radiant power to reach the whole volume of the room. The period of low-end radiant heaters has been outdated a long time ago. We strive to make clear to customers that a heater with a radiation rate of 20% (as most models of radiant heaters of mass-market retailing) and a another with 60% have no more in common than a twingo and a ferrari…
If the power needs are well calculated, the heater well placed in the room, a quality infrared heater will definitely bring you comfort and savings.“

What constitutes an infrared heater? What makes a heater more or less effective?
“Not all infrared heaters are composed of a carbon film. Our heaters have been tested by the University of Technology in Stuttgart with a radiation rate of 71%. This figure makes our products leading heaters from the radiation emission and therefore energy efficiency point of vue. Our heaters are made of a copper-nickel alloy mesh that has nothing to do with a carbon film as inexpensive as ineffective. The emissivity of the material surface (glass, metal as opposed to aluminium) as well as the presence of a high density insulant on the back (to avoid heating the wall) are also important factors. Readers are encouraged to have a look at the independent study of the engineering firm GENIO which ranks our heaters as the most economical solution across all heating methods. “

Is the infrared heater suitable for all situations and configurations (veranda, bathrooms)? Not always
“Users and installers must not lose sight of one essential point. The position of the heater is important in achieving thermal comfort and energy savings. Unlike heaters operating mainly by convection (convectors, inertia heaters, water heaters) that “‘fill the room with hot air” over time, the radiation of the infrared heater accumulates in the structure (floor, walls, ceiling, furnitures). So do not place it in a corner, close to the floor, next to a huge wardrobe!
The radiation passes through the glass walls (which is valuable in winter for the rays of the sun). This also means if you place an infrared heater in front of a glass wall in a distance of 2-3 meters (veranda, window), part of the radiation goes outside… If all the walls are made of glass like in a veranda, it becomes impossible to place efficiently a far infrared heater. Therefore in that case it is better to place a near infrared heater whose range is much more reduced creating a heat cone instead. We can feel the heat inside of the cone, but not on the outside. So do not confuse and infrared with an infrared!When talking about bathrooms, one question often comes into mind. If the bathroom is tiled from the floor to the ceiling and the material is smooth and reflective, the infrared heater is not really suitable because the radiation behaves like a ping pong ball and won’t accumulate in the structure, which is essential to feel the comfort. When the situation is intermediate (partially tiled and of an absorbant material) we oversize the power needs of about 20%. Count 65W per m2 for bathrooms that require a higher temperature of comfort than other rooms.”

Is the infrared in heating hazardous to health? False
“The infrared is divided in 3 main categories IR-A, IR-B, IR-C. The IRA are those which penetrate the skin the most and can cause prematurely ageing of the skin under certain conditions of prolonged exposition. The IRA are emitted as a part of activities without contact with humans. The indoor infrared heating for dwellings is a far infrared radiation FIR. Also, there is absolutely no risk to humans. Note that infrared is everywhere in our environment.”
