What is
Radiant Heat? |
|
|
Radiant heating heats in
the same manner that the sun warms the earth. The
sun's infrared rays strike the earth, objects and
people. The radiant energy is absorbed and each
object becomes a heat reservoir, which then heats
the ambient air. An example of this is a car that
is left in the sun will be warmer and dry more
quickly than a car left in the shade because the
sun's infrared rays are heating the car's surface
directly. The car left in the shade is being warmed
by the ambient air and will not dry as rapidly.
Each radiant heater incorporates highly reflective steel reflectors, which are
mounted in such a way as to permit free thermal expansion and are easily detachable
for cleaning, or whenever access is required. The gas burner fires into one end
of the emitter tube. The emitter tubes are heated by the passage of hot combustion
gases and the hot tubes emit infrared radiant heat, which is directed downwards
by the reflector towards the occupied workspace.
What AmbiRad has perfected is the ability to bring the sun's warmth indoors.
Turning on a radiant heater results in the warmth being felt quickly. Radiant
energy directly heats surfaces and not the surrounding air, so it is also
an economical form of heating. |

What is
the difference between conventional forced air
systems and radiant tube heating? |
Warm
Air |
Radiant
Heat |
Warm air
heaters heat air which then warms the surroundings
where people work. In buildings where doors
are opened regularly, high air change rates
occur which result in extremely high heat
losses.
|
Radiant
heat is not absorbed by the air, so it is
ideal for buildings which have high air change
rates. Radiant heat offers considerable energy
savings over warm air systems, especially
under otherwise difficult conditions. |
Directing
heat to working areas is difficult with warm
air heaters. Consequently, a garage heated
by warm air will have cold spots at the working
level and wastefully high temperatures at
the roof. |
Radiant
heat is transmitted by infrared waves
and is directional. Correct location of radiant
heaters ensures that cold spots are avoided. |
Drafts
and natural convection currents make it difficult
to control warm air movement within a building.
As warm air rises to areas where it is not
beneficial, heating costs also rise. |
Zone control
of radiant heaters permits flexible management,
allowing selected areas of the work- shop
to be heated to different temperatures as
required. |
Hot
air rises, therefore the roof of a workshop
heated with warm air will be substantially
hotter than the working area beneath. Poor
roof insulation, a common problem in older
buildings, will allow this heat to escape,
further increasing fuel costs. |
Radiant
heaters minimize roof heat losses by directing
heat downwards to the area that requires
heating. |
Warm
air heats workshop space slowly. In order
to be effective it is necessary to heat all
the air in the building. While the air gets
to the required temperature, extra fuel is
burned and the work force remains cold. |
Radiant
heat warms up cold bodies directly without
heating the whole building. Consequently,
radiant heating responds more quickly than
warm air to the needs of a workshop. The
shorter warm up periods save fuel and allow
the heating system to match flexible, modern
working arrangements. |
Warm
air heaters rely on movement of air to heat
the
work space. In areas where cleanliness is
essential for production and other work,
drafts from a hot air blower will stir up
unwanted dirt and dust. In addition, rapid
air movement actually has a cooling effect
on the body. |
Radiant
heating does not circulate air, therefore
airborne particles are reduced |
