An electric water boiler, also called a thermo pot, is a consumer electronics small appliance used for boiling water [1] [2] and maintaining it at a constant temperature. It is typically used to provide an immediate source of hot water for making tea, [1] hot chocolate, coffee, [1] instant noodles, or baby formula, or for any other household use where clean hot water is required. They are a common component of Japanese kitchens and the kitchens of many East Asian countries but are found in varying use globally. Some thermo pots are designed with a feature that can purify water. [3]


Black tea is typically steeped at 95 °C (203 °F) while green tea is steeped at under 80 °C (176 °F). A number of thermo pot models offer an adjustable target temperature. [4]


An electric water boiler consists of a water reservoir with a heating element at the bottom. Some models offer multiple temperature settings. Other models are part of larger water systems that boil water and provide hot, cold, and lukewarm water. Water may be dispensed in various ways, e.g. by pouring, an electric pump or by pressing a large button that functions as a diaphragm pump. Electric water boilers have a built in thermostat that detects when water has reached its boiling point of 100 °C (212 °F) to automatically shut off[ citation needed ].


Sedimentation is the accumulation within the water reservoir of natural minerals that exist in trace amounts in municipal water mains, mainly calcium carbonate. Heating the water causes the minerals to separate and fall to the bottom of the reservoir. This buildup can eventually create a variety of noises in gas boilers, reduce the efficiency of the unit and give rise to a sulfur (or rotten-egg) smell. Vinegar can be used to descale electric kettles. [5]

Espresso machine type of coffeemaker that makes espresso

An espresso machine brews coffee by forcing pressurized water near boiling point through a "puck" of ground coffee and a filter in order to produce a thick, concentrated coffee called espresso. The first machine for making espresso was built and patented in 1884 by Angelo Moriondo of Turin, Italy. An improved design was patented on April 28, 1903, by Luigi Bezzera. The founder of the La Pavoni company bought the patent and from 1905 produced espresso machines commercially on a small scale in Milan. Multiple machine designs have been created to produce espresso. Several machines share some common elements, such as a grouphead and a portafilter. An espresso machine may also have a steam wand which is used to steam and froth liquids for coffee drinks such as cappuccino and caffe latte.

Rice cooker container or kitchen appliance dedicated to cooking rice

A rice cooker or rice steamer is an automated kitchen appliance designed to boil or steam rice. It consists of a heat source, a cooking bowl, and a thermostat. The thermostat measures the temperature of the cooking bowl and controls the heat. Complex rice cookers may have many more sensors and other components, and may be multipurpose.

Water heating Thermodynamic process that uses energy sources to heat water

Slow cooker Countertop electrical cooking appliance used to simmer food

A slow cooker, also known as a crock-pot, is a countertop electrical cooking appliance used to simmer at a lower temperature than other cooking methods, such as baking, boiling, and frying. This facilitates unattended cooking for many hours of dishes that would otherwise be boiled: pot roast, soups, stews and other dishes. A wide variety of dishes can be prepared in slow cookers, including ones typically made quickly, such as cocoa and bread.

The Japanese kitchen is the place where food is prepared in a Japanese house. Until the Meiji era, a kitchen was also called kamado and there are many sayings in the Japanese language that involve kamado as it was considered the symbol of a house. The term could even be used to mean "family" or "household". Separating a family was called kamado wo wakeru, or "divide the stove". Kamado wo yaburu means that the family was broken.

Kettle appliance for boiling water

A kettle, sometimes called a tea kettle or teakettle, is a type of pot, specialized for boiling water, with a lid, spout, and handle, or a small kitchen appliance of similar shape that functions in a self-contained manner.

An electric stove 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 stoves which required more labor to operate and maintain. Some modern stoves come in a unit with built-in extractor hoods.

Electric heating process in which electrical energy is converted to heat

Electric heating is a process in which electrical energy is converted to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators.

Gongfu tea ceremony chinese tea ceremony

The gongfu tea ceremony or kung fu tea ceremony, is a kind of Chinese tea ceremony, involving the ritual preparation and presentation of tea. It is probably based on the tea preparation approaches originated in Fujian and the Chaoshan area of eastern Guangdong. The term literally means "making tea with skill". Today, the approach is used popularly by teashops carrying tea of Chinese origins, and by tea connoisseurs as a way to maximize the taste of a tea selection, especially a finer one.

Coffee preparation process of turning coffee beans into a beverage

Coffee preparation is the process of turning coffee beans into a beverage. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be roasted, the roasted coffee beans must then be ground, the ground coffee must then be mixed with hot water for a certain time (brewed), and finally the liquid coffee must be separated from the used grounds.

Instant hot water dispenser appliance that provides hot water

An instant hot water dispenser or boiling water tap is an appliance that dispenses water at about 94 °C (201 °F) (near-boiling). There are hot-only and hot and cool water models, and the water may be filtered as well as heated. Instant hot water dispensers became popular in the 1970s. Instant hot water dispensers are very similar to portable shower devices; the latter is fitted with a heating element and quickly heats up water, once a switch has been activated.

Coffeemaker device for making coffee

Coffeemakers or coffee machines are cooking appliances used to brew coffee. While there are many different types of coffeemakers using a number of different brewing principles, in the most common devices, coffee grounds are placed into a paper or metal filter inside a funnel, which is set over a glass or ceramic coffee pot, a cooking pot in the kettle family. Cold water is poured into a separate chamber, which is then boiled and directed into the funnel. This is also called automatic drip-brew.

Windermere kettle

A Windermere kettle is a form of steam-operated tea urn or samovar installed on some steam launches. They are a metal vessel containing a few pints of water. Inside the vessel is a steam heating coil. When hot or boiling water is required, a valve is opened and steam from the boat's propulsion boiler is passed through the coil, heating the water. Their exhaust is either overboard or up the funnel, as convenient. Windermere kettles are rapid boilers and can heat enough water to make a pot of tea in only a few seconds.
