Definition and History of Electric Stoves
– Electric stove is an appliance with integrated electrical heating device for cooking and baking.
– It uses electricity as a source of heat.
– Electric stoves replaced solid-fuel stoves due to ease of use and maintenance.
– Some modern electric stoves come with built-in extractor hoods.
– Stove burners and controls may incorporate thermostats for temperature regulation.
– George B. Simpson was awarded a patent for an electro-heater surface in 1859.
– Thomas Ahearn filed a patent for an Electric Oven in 1892.
– The electric stove was showcased at the Chicago World’s Fair in 1893.
– William Hadaway was granted a patent for an Automatically Controlled Electric Oven in 1897.
– David Curle Smith obtained an Australian patent for his electric cooking stove, known as The Kalgoorlie Stove, in 1905.
Development and Acceptance of Electric Stoves
– Three companies started selling electric stoves in the United States in 1908.
– Early electric stoves faced challenges such as high electricity costs and poor temperature regulation.
– The invention of nichrome alloy improved the cost and durability of heating elements.
– By the 1930s, electric stoves gained acceptance due to technological advancements and decreased power costs.
– Electric stoves were marketed by electrical utilities to promote demand for electric power.
Variants of Electric Stoves
– Early electric stoves had resistive heating coils and iron hotplates.
– Composite heating elements with resistive wires encased in metal tubes were introduced.
– Glass-ceramic cooktops became popular in the 1970s, providing quicker heating and easier cleaning.
– Induction stoves use electromagnetic induction and require ferromagnetic cookware.
– Different types of heating elements and surfaces offer various advantages and price ranges.
Electricity Consumption of Electric Stoves
– The typical electricity consumption of one heating element ranges from 1 to 3 kW, depending on its size.
– Electric stoves consume more electricity compared to wood, coal, or gas stoves.
– Advances in technology have improved energy efficiency in electric stoves.
– Energy-saving features and smart controls are being incorporated into modern electric stoves.
– Using energy-efficient cooking techniques can help reduce electricity consumption.
Subtopics
– Introduction to Electric Stove: Common household appliance, uses electricity to generate heat, found in kitchens, provides a cooking surface, available in different sizes and styles.
– Energy Efficiency: Varies depending on stove model, energy-efficient options available, can reduce electricity consumption, some models have energy-saving features, proper usage can help conserve energy.
– Power Consumption: Typically ranges from 1000 to 3000 watts, higher wattage means faster heating, power consumption affected by cooking duration, different heat settings consume different amounts of electricity, regular cleaning and maintenance can optimize power usage.
– Safety Features: Many stoves equipped with safety mechanisms, automatic shut-off in case of overheating, child lock feature prevents accidental use, indicator lights for hot surfaces, timer function to prevent overcooking or burning.
– Environmental Impact: Electric stoves produce no direct emissions, electricity generation may have environmental consequences, choosing renewable energy sources can reduce environmental impact, energy-efficient models can help lower carbon footprint, proper disposal of old stoves is important for minimizing waste.

An electric stove, electric cooker or electric range is a stove with an integrated electrical heating device to cook and bake. Electric stoves became popular as replacements for solid-fuel (wood or coal) stoves which required more labor to operate and maintain. Some modern stoves come in a unit with built-in extractor hoods.
The stove's one or more "burners" (heating elements) may be controlled by a rotary switch with a finite number of positions (which may be marked out by numbers such as 1 to 10, or by settings such as Low, Medium and High), each of which engages a different combination of resistances and hence a different heating power; or may have an "infinite switch" called a simmerstat[citation needed] that allows constant variability between minimum and maximum heat settings. Some stove burners and controls incorporate thermostats.[citation needed]
