About Electric Heaters
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.

Types of Electric Heaters
- use electricity to warm air.
- 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.
- 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.
-
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.
- 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.
-
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.
- are used to heat drums or their contents. Most drum
heaters can accommodate various sizes of drums and many different substances.
- 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.
-
blow hot air down into the area needing heat and rapidly heat it to
a desired level.
- 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.
-
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.
- 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.
-
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)
- are the same as immersion heaters except that
they hang over the side of a tank into the heated material.
-
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.
- are electric heaters that require minimal space.
-
convert electric energy into heat. This is an irreversible conversion
of electricity into heat; these heaters are often used for water and
other fluids.
- are used to heat air, solids or liquids generally
for custom heating purposes. These can sometimes be designed
for mobile
jobs in various fields.
