Electric heaters use nichrome wire as the heating element due to its high electrical resistance and heat tolerance. Nichrome, an alloy of nickel and chromium, efficiently converts electrical energy into heat. Copper wire is often used for external wiring because of its excellent conductivity. High-temperature-resistant insulating materials are necessary to prevent short circuits.
