2. Infrared heater reviews
Infrared heaters become more popular since it heats fast, energy-
efficient, safer, and also it is green. Even have certain specifications and
should be used only in certain situations, Nowadays infrared heaters
have used in large-scale on industrial, hospital, and
household.Basically, an infrared heater is almost the same as
conventional heating. Infrared heaters are different, which uses
infrared radiation principles[1].Unlike conventional heating systems
that warm spaces primarily through convection heating, radiant
heating systems directly heat occupants or objects. However, to get
comfort heating, there must be reasonably even accumulated values of
heat throughout the comfort zone.The unique characteristic of this
energy is not absorbed by air, and doesn’t heat until hitting the object
and absorbed by solid object, and this energy can be controlled and
directed specifically to objects by optically designed reflectors. This
infrared energy travel at the speed of light and convert to heat up on
contact with an opaque object (people, the floor, a building).

4. Advantages of Infrared Heaters
Heat object without heating air : Infrared heaters heat at the object level
directly and concentrated where it is really needed without heat air. Different
with conduction and convection, radiant method only heats the object when
hitting the object and absorbed by object.
Zone Control Flexibility: Because infrared energy doesn’t absorb by air and only
heat object when hitting the object, therefore, we can divide any area where we
want to heat and maintain a different comfort level in each area.
Staging : The staging feature allows only a portion of the equipments
total capacity to be used. These systems allow a more consistent and uniform
means of maintaining a specific comfort level and avoid the “peak and valley”
syndrome.
Reduced operating cost : Since infrared energy doest absorbed by air and only
absorbed by abject, there is no energy loss. This mean you don’t need to cost for
loss energy absorbed by air. Infrared heater technology can save up to 50%
operational cost compare with conventional heaters. However actual saving
cost will vary depending on factors such us insulation, ceiling high and type of
construction.
5. Instant heat : Since there is no need to wait for heat
buildup, infrared heaters produces virtually instant heat.
You just need to turn on the heaters prior to heating
requirements.
Negligible maintenance : Infrared heaters are easy
maintenance. There are no moving parts or motors to wear
out; no filters or lubrication required.
Clean : An electric infrared heater is the cleanest
method of heating. Electric infrared heater adds nothing to
the air nor takes anything from it.
Safe : UL listed, No open flame, No moving parts to
malfunction, No fuel lines to leak, No toxic byproducts of
combustion.
Efficient : All infrared heaters convert energy to heat at
100% efficiency.
6. Types of Infrared Heaters
Metal-sheathed tubular heaters : Tubular heaters generate infrared heat in the
2.5 – 3 μm range of the electromagnetic spectrum. The practical maximum
temperature is 900˚F with a maximum sheath temperature of 1500˚F (Incoloy
sheath). They’re commonly mounted into aluminum housings with polished
reflectors. (http://www.deltat.com/tubular_metal_heaters.html)
Gas fired catalytic : No chimney or flue is required so all the heat
generated goes to warming the room. Burley’s flueless gas fires and stoves burn
extremely cleanly due to their advanced technology. Any remaining waste gases
pass through a catalytic converter to form carbon dioxide (which is harmless at
these levels and is present in fresh air.)
Ceramic emitters : Ceramic infrared heating elements are
efficient, robust heaters which provide long wave infrared radiation. They are
used in a diverse range of industrial processes such as thermoforming, paint
curing, printing and drying. They are also used very effectively in infrared
outdoor heaters and infrared saunas. (http://www.ceramicx.com/en/ceramic-

7. Quartz tubes : A quartz tube furnace is an electric
heating device extensively used in material research. For
example, ceramic research, wafer sintering and annealing
and powder baking. The lengths of the quartz tubes are
different. For experiments in laboratories the size of tube is
from 1″ to 13″. The temperature is controlled via a feedback
from a thermocouple. The temperature controllers often
allow the operator to program the heating, dwelling and
cooling rates.

Quartz lamps : A mercury-vapor lamp that is enclosed
in a quartz container instead of a glass container mercury-
vapor lamp – ultraviolet lamp that emits a strong bluish
light (rich in ultraviolet radiation) as electric current passes
through mercury vapor.
