The heating element in electric heaters and irons is made from an alloy of nickel and chronium called nichrome. It is usually made in the form of wire. The wire is often wound around a flat sheet of mica for support. Mica is a thin layered mineral that can withstand high temperatures.
Because Copper is an excellent conductor of electricity it would take too much copper wire to make a heating element having sufficient resistance to fit into the small space provided in any normally-sized electric heater.
For that reason heating elements must be made from metals which have a much higher electrical resistance than Copper. Special alloys of metals such as Iron, Cobalt, Nickel, Zinc and Manganese have been invented for this purpose.
A heating element is a heating element, it doesn't need a further name. There are many brands of electrical goods which vary from country to country.
Inside a heater element is aluminium oxide for insulation and it surrounds a nickel resistance wire.
The main feature of an efficient electric heater is, that is used up to 30% less engery than a conventional electric heater. This reduces the cost of the heater.
Copper and aluminium are used for electric cables.
An electric water heater in a hot tank is called an immersion heater and many of those run at 3 kW with a thermostat to control the max temperature. Power showers use a type of water heater that heats the water at the point where it is used, without a tank. They run at 6-8 kW and are also controlled by a thermostat.

Can heat energy be converted to light energy and how?
Nichrome wire is commonly used for resistance wire for heater elements and it is a non-magnetic alloy of two elements nickel and chromium. It has high resistance and resists oxidation. The electrical resistivity is about 65 times that of copper.
If it is a electric water heater, then one of the heating elements are burned out.

An electric room heater may be used to heat a room when it is cold, they are commonly used in the winter. An electric room heater may also be used to discharge the heat outside and keep the house cool.
They're made of Tungsten.
An immersion electric heater usually uses nichrome wire as the heating element. Nichrome is highly resistive, and by applying a voltage, we can get it pretty hot. Nichrome is used as the heating element in toasters and on electric range elements as well as lots of other places.
The most common element used in making filaments is Tungsten.
If the lighter bulb had oxygen in it , the hot glowing filament would react with the oxygen, thereby destroying the filament. If the filament is destroyed, then there is no light. So an inert gas is used, because it will not react with the heated glowing filament. Hence the filament stays alight.
Light bulb filaments are usually made of tungsten, which has a very high melting point. Occasionally carbon is used as a filament.
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
