Cove Heaters[edit]

Cove Heater systems are specifically designed in configuration for maximum instant human thermal comfort heating. Electric fast-acting radiant cove heating units provide a highly efficient radiant surface for maximum instant human comfort heating.[1] Cove heaters are designed to be located at the junction of the ceiling and wall, a feature that provides optimum heating and saves floor space while providing better latitude for furnishings arrangement.[1] Its radiant transfer is a linear function from warm objects to colder objects. Cove heaters produce infrared heat which passes through the air as energy striking everything in its path such as floor, walls and furniture so that our bodies need not accelerate their rate of heat dissipation for optimal thermal comfort.[1]

The key to the efficiency and effectiveness of this system is the emissivity of the emitting surface of the panel. If the emissivity is low, a greater percentage of the input power is dissipated in convection or conduction. If the emissivity is high, as it is in this system, the energy beamed from the panel as infrared heat therefore emits at the speed of light (186,282 miles per second) and reaches the body and objects instantly, and also instantly becomes converted to heat in the surface of the body and or objects.[2] [3] The system’s effectiveness is also enhanced since it beams energy at a wave length which the human skin can most comfortably absorb.[4] It is this direct warming that gives the sense of optimal thermal comfort and well-being at lower air temperatures, thus lowering operating costs.[1] The typical body has between 20 ft2 to 22 ft2 of surface area[4] which serves as a radiator for releasing heat via radiation to lower the body temperature or as an absorber to take in radiant energy to raise the body temperature. The skins emissivity is around 0.98 which makes it almost perfect as a radiator and absorber.[4]

Common Misconceptions[edit]

It is a common belief that all heat only rises. According to thermodynamics, Heat, (or energy) does not rise, it is heated gases or heated fluids that exhibit this.[5] The term “Radiant Heat” is a misnomer since there is no heat in a radiant wave, there is “energy” which converts to heat after striking an object. For example, the solar energy from the Sun sends no heat to the Earth, it sends radiant waves or energy that can produce heat after the waves strike an object. When this energy strikes an object it causes the molecules of the absorbing object to vibrate. This vibration converts the energy into heat.[6] Infrared heat is invisible light and does not contain harmful radiation waves. This system creates a man-made sunlight type of heat. Much of the energy from the Sun arrives on Earth in the form of infrared radiation. Sunlight at zenith provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 527 watts is infrared radiation, 445 watts is visible light, and 32 watts is ultraviolet radiation [7]

‘’’Infrared Heats Everything’’’ – Since this system primarily utilizes infrared heat, it not only heats the air, it heats everything in its path. Air is low in density therefore it is easier for it to dissipate energy or change temperatures. By warming higher density objects such as furniture and the floor it creates thermal mass within the heated space and allows for more optimal thermal comfort with lower operating costs. [8]

‘’’Zone Controlled’’’ – Individual thermostats in each room can be specifically tailored to individual area requirements. The result is economical heating and automatic heating comfort for each heating area instead of heating the entire building with one centrally located thermostat.[9] According to ANSI/ASHRAE Standard 55, Thermal Environmental Conditions for Human Occupancy, "there are large variations, both physiologically and psychologically, from person to person, it is difficult to satisfy everyone in a space. The environmental conditions required for comfort are not the same for everyone." ‘’’Rapid Response’’’ – Cove heaters heat instantly and are an ‘even’ heat. It is draftless with minimal temperature differential from floor to ceiling. Within a case study during a record cold winter, thermal analysis showed the radiant panel system provides localized thermal comfort after thermostat set back or recovery within 10 to 15 minutes and room-wide comfort in approximately 45 minutes. [10] ‘’’Clean and Quiet’’’ – Since this heater design has no moving parts or combustion it is a silent heater and with no fans in operation there are no filters to clean. ‘’’Save Space and Floor Area’’’ – Since this system is mounted high on the wall, all floor space can be utilized for greater freedom of furnishings arrangement. This also allows for safer operation as the system is high and out of reach.


Description of Components and other observations pertinent to this Radiant Heating System:

Front Panel[edit]

The heat panel is most commonly composed of high heat transfer aluminum alloys and coated with specific high emissivity flat, matted finish, enamel or powder coated with the basic and prime object of having a surface and body condition which assures a maximum emissivity factor. The human skin has a 98% emissivity and thus also absorptivity factor of 98%. Note: a good emitter is also a good absorber and vice versa. (2) The panel is designed and constructed to operate at a temperature which results in the radiation of electro-magnetic energy (infrared) in wave lengths from 4.7 to 5.6 microns which have been found to be most compatible with what the human body can best absorb for maximum comfort.(Skin Infrared Microns absorb source)

High Emissive Finish[edit]

A high emissive finish with a flat or matte coating used in combination of the basic substrate (aluminum alloys), results in a system of high efficiency. It does not produce more B.T.U.’s per watt of electric energy but rather distributes this energy faster than other heat systems (speed of light). But this high speed of distribution in itself is not alone a factor in the high efficiency of this system. It is important that as much of the input energy (heat) to the panel be radiated with little loss to convection and conduction. Other factors such as surface temperature, surface aspect ratio (20 to 1 i.e. length to height most desirable to reduce induced convection to the minimum) and total effective surface are all important; but the emissivity of the panel surface is the key to high efficiency for rapid comfort heating at minimum power consumption.

Reflector or Back Shield[edit]

The reflector is a vital part of the system since it reflects back through the panel all wave energy emitted from the back surface of the Front Panel. This functions much like how a headlight reflector reflects light energy forward for a brighter beam. For human heating it is not desirable to have a perfect parabolic reflector surface as it is desired that the radiation of energy be as diffused throughout the space to be heated as much as possible. (thermal comfort source) (However for certain industrial baking, drying or curing applications an effective parabolic reflector system used with the panel is desirable to focus the energy exactly to the product in process.)

Heating Element[edit]

The heating element is one of the electric resistance type. These elements are known as Calrod heating Elements. A heating element converts electricity into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. Of interest is the fact that regardless of the source of heat – this heat increases the activity within the atoms of the structure. The increased movement of the internal elements of the atoms results in great emissions from each atom of electro-magnetic energy which is beamed into space equally in all directions.(electromagnetic energy source) Also of interest is the fact that CO2 moisture-laden air have a high affinity for energy in this wave length thus resulting in instant heating of these particles and these in turn on impact with oxygen and nitrogen heat these in direct proportion to the angle of impact. (electromagnetic energy source) Thus the air in the heated space is also heated indirectly but sufficiently to permit temperature control by a standard air type thermostat from anywhere in the within the heated area.


The object of this heating system is to directly and instantly heat the human body and/or other objects. To do this, it is required that the system beam energy into the desired space with a safe infrared wave length which the human body and/or objects can best absorb. To provide that this must be done with maximum efficient use of input power, it is essential not only that the surface of the panel be heated to the exact temperature range but also that the surface be a most efficient emitter. Because of the exacting requirements, the composition of this type of heating system requires the proper and successful arrangement of specific components to achieve these results.

Non-English sources[edit]

You declined Wikipedia talk:Articles for creation/Alexander Karasyov with a comment that said "English article needs English sources". That's not correct; per WP:NONENG non-English sources are also acceptable though English sources are obviously preferred. Yours, Huon (talk) 18:42, 21 April 2013 (UTC)

My point is that you need at least one English source. Otherwise the verification falls apart.137Fy (talk) 19:26, 21 April 2013 (UTC)

That is not correct. An article can be verifiable even if all of the sources are not in English. Arthur goes shopping (talk) 17:02, 24 April 2013 (UTC)

Your recent decline justification was incorrect. There is no requirement for references to be in English. Please don't decline articles using that as valid criteria. Regards and happy editing, FoCuSandLeArN (talk) 21:27, 24 April 2013 (UTC)

I came here to say the same thing, the relevant Wikipedia policy is part of our Verifiability policy at WP:NOENG. It's reasonable to have doubts about citations you can't read, and there are a variety of strategies for dealing with non-English (or, analogously, off-line) sources, but they are permitted by policy. Have a great day! --j⚛e deckertalk 14:20, 1 May 2013 (UTC)
