Electric heaters and electric water heaters can be
any heating device that is powered by electricity and creates
heat. Electric heaters are used to heat a variety of materials in domestic,
commercial and industrial settings. Electric heaters can also be used
to heat a specific area, shape or melt materials or even preserve the
molten state of a substance. Some heaters use Peltier modules to produce
heat, and some use light or other methods. Electric water heaters are
available in many unique sizes, shapes and heating configurations. An
electric heater may heat an object from room temperature up to over 1300°F.
Various grades and alloys of metal are the material of choice for the
heating element itself.
Electric heaters can utilize a variety of methods to move and transfer
heat. A standard hard wired electric heater can have a central heating element and then use fans to force the hot air throughout
a larger system of ductwork, such as duct
heaters. A ceramic
heater or
cartridge heater has heating elements that come into direct
or near-direct contact with the area or substance needing heat. An example
of a ceramic heater would be a heater used to keep prepared hot food
products warm for consumption. The heating
element directly warms the substance rather than indirectly via
fans or ductwork.
Drum heaters are an example of an industrial heating unit that is often
used as part of a broader manufacturing process. Drum heaters are mobile
and attach directly to the drum needing heat rather than being permanently
part of a heating chamber. These drum heaters are used to heat the substance
within the drum, such as wax, grease or another gelatinous solution, so
the substance can be poured or pumped out of the drum once liquefied
for use in another stage of a process. Rapid as opposed to constant
heat is desired in applications such as this.
When looking for an electric heater, it is important to identify its
use. Does it need to heat a room, melt a substance
or shape material? Each application for electric heaters will require a standard for material make-up, temperature capacity and power.
Other heating systems can involve coal, wood, gas or water. Electric
water heaters are often more environmentally sound and economical than
other heating methods. Safety is another crucial concern when purchasing
a heater. One must take into account how certain heaters react with
certain substances. Some heaters are better than others when heating
liquids or gases, or when heating small spaces. Safety features are often
built into many electric heaters, such as auto shut-offs or warning signals.
Electric Heaters and Electric
Water Heaters Image Provided by Thermal
Devices
Band heaters are o-shaped heating devices that secure
around an element. They can clamp around the outside of a cylindrical
element and heat from the outside or clamp around the inside.
Cartridge heaters are compact cylindrically shaped heaters which
are used primarily for immersion applications. They also have a protective
sleeve or sheath protecting the heating element from the immersion
liquid.
Cable heaters
and coil heaters are formed from straight pieces of heating cable. These
heating elements are formed into coils, spiral, sinuated, star wound
or other patterns.
Ceramic fiber heaters contain a layer of ceramic fiber insulation
combined with a heating element. It is usually an industrial heater
and available
in cylindrical and flat configurations.
Circulation heaters
are used primarily to heat fluid streams in motion. Fluid runs through
the heater, which increases the stream temperature; any liquid or gas
is generally suitable for use with a circulation heater.
Drum heaters are used to heat drums or their contents. Most drum
heaters can accommodate various sizes of drums and many different substances.
Duct heaters can heat moving gas streams and heat air as it moves
through the heater. It is also sometimes used to intensely heat an
object at
the end of a stream of gas.
Electric downflow heaters
blow hot air down into the area needing heat and rapidly heat it to
a desired level.
Flexible heaters are devices that may be formed to fit a variety
of items. Flexible heaters are made from pliable materials such as
rubber
or neoprene so they can be formed to fit a variety of circumstances.
Foil heaters
are made of flexible heater wire bonded to a thin aluminum substrate.
The wire can be bended into a variety of shapes and act as the transport
for the heat used.
Immersion heaters are used when it is necessary to immerse a heater
in the material being heated. Examples of such materials can be water
or liquid polymers.
Infrared heaters
use a shield to reflect radiant heat onto a surface that is heated.
Types of infrared heaters include metal-sheathed tubular heaters,
quartz tubes, quartz lamps, gas fired catalytic, flat-faced panels and
ceramic emitters. (www.infraredheaters.net)
Over-the-side heaters are the same as immersion heaters except that
they hang over the side of a tank into the heated material.
Radiant heaters
diffuse energy heat rays in a 160 degree arc, and deliver heat evenly.
They can maintain an almost uniform area temperature so that there is
not more than 2 degrees variation in the space; many radiant heaters
are so exact that heat can be directed to specific locations.
Strip heaters are electric heaters that require minimal space.
Thermoelectric heaters
convert electric energy into heat. This is an irreversible conversion
of electricity into heat; these heaters are often used for water and
other fluids.
Tubular Heaters are used to heat air, solids or liquids generally
for custom heating purposes. These can sometimes be designed
for mobile
jobs in various fields.
Common Terms Related to Electric Heaters
Amps – The
meter-kilogram-second unit of electric current that is equivalent to the
steady current produced by one volt applied across a resistance of one
ohm.
British Thermal Unit (BTU) – Used
for measuring a quantity of heat. One BTU is the quantity of heat necessary
to raise the temperature of 1 pound of water 1°F.
Celsius – The metric temperature
scale in which water freezes at zero degrees and boils at 100 degrees,
designated by the symbol "C".
Circuit – An electrical device
providing a trail for electrical current to flow as found in electric
heaters.
Duct – An enclosure in which
air is moved that is primarily constructed from sheet metal.
Fahrenheit – The heat scale
on which water freezes at 32 degrees and boils at 212 degrees, abbreviated
by the letter F.
Fan – A device that creates
currents of air, sometimes built in electric heaters to push air out from
the unit.
Heating Coil – Any coiled element
that serves as the source of heat. These heating coils are the main
source of heat on electric heaters.
Heating Element – The component of
the heater which is responsible for conducting the heat from electric
heaters.
Hertz – In alternating current
(AC electricity), the number of cycles per second, denoted Hz.
Peltier Modules – Jean Peltier
in 1834, discovered that passing an electric current through the junction
of two different conductors cools or heats the junction depending on the
direction of the current. The modern Peltier modules are made out of semiconductor
material, and are used in thermoelectric devices.
Radiationange - The distribution of
energy by electromagnetic waves, of a generally long wave-length.
Sensor – Any device that reacts
to a change in the environment being measured, by signaling of the change
via audible or visual means.
Therm – A measurement of heat
equal to 100,000 BTU.
Thermocouple – Measures the
difference in potential created at the junction of two different metal
wires, which feed from the measuring instrument. (http://www.iqsdirectory.com/thermocouples/)
Thermostat – An automated device for
controlling temperature on electric heaters.
Thyristor – A power semiconductor
device with three terminals called the gate, cathode and anode. Its state
becomes conductive (ON) or blocking (OFF) depending on the behavior of
these terminals.
Volts – The difference of possibility
between two points in a conducting wire with a constant current of one
ampere.
Watts – The meter-kilogram-second
unit of power equal to the power produced by a current of one ampere across
a potential difference of one volt, 1/746 horsepower.
