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. ‘’’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.

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.
87:(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. The system’s effectiveness is also enhanced since it beams energy at a wave length which the human skin can most comfortably absorb. It is this direct warming that gives the sense of optimal thermal comfort and well-being at lower air temperatures, thus lowering operating costs. The typical body has between 20 ft2 to 22 ft2 of surface area 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.
338:
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.
292:‘’’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

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.

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.)
346:
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

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).

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
