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 in an enclosed reservoir. 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. Smaller units are portable. Some thermo pots are designed with a feature that can purify water. [3]

Components

An electric water boiler is a device comprising a water reservoir equipped with a heating element positioned at the bottom. While some models offer the convenience of multiple temperature settings, others are integrated into larger water systems capable of boiling water and dispensing it in various forms: hot, cold, or lukewarm. Dispensing methods vary and can include pouring, utilizing an electric pump, or pressing a large button that acts as a diaphragm pump. [4] Additionally, electric water boilers are typically equipped with a built-in thermostat that senses when the water has reached its boiling point of 100°C (212°F), automatically shutting off to prevent overheating.[ citation needed ]

Sedimentation

Sedimentation refers to the gradual accumulation of natural minerals within the water reservoir, typically found in trace amounts in municipal water mains. These minerals, predominantly calcium carbonate, tend to settle at the bottom of the reservoir as the water is heated. Over time, this sediment buildup can lead to several issues. Firstly, it can generate various noises within gas boilers due to the disturbance caused by the sediment. Additionally, the accumulation can impair the efficiency of the unit, as the sediment acts as an insulating layer, hindering the transfer of heat. Moreover, the presence of sediment can result in the development of an unpleasant sulfur or rotten-egg smell in the water.

To address sediment buildup in electric kettles, descaling agents such as vinegar or citric acid are commonly used. These substances effectively dissolve and remove the accumulated minerals, restoring the kettle's performance and eliminating any associated odors. [5]

Uses

Some electric water boiler models enable tea to be steeped at a desired, adjustable temperature. [6]

<span class="mw-page-title-main">Heat pump</span> System that transfers heat from one space to another

A heat pump is a device that uses work to transfer heat from a cool space to a warm space by transferring thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. In cold weather a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in warm weather. As they transfer heat rather than generating heat, they are more energy-efficient than other ways of heating or cooling a home.

A boiler is a closed vessel in which fluid is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.

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. 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 caffè latte.

<span class="mw-page-title-main">Thermoelectric effect</span> Direct conversion of temperature differences to electric voltage and vice versa

The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side.

Electric heating is a process in which electrical energy is converted directly 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 or kung fu tea, literally "making tea with skill", is a traditional Chinese tea preparation method sometimes called a "tea ceremony". It is probably based on the tea preparation approaches originating in Fujian and the Chaoshan area of eastern Guangdong. The practice involves using smaller brewing vessels and a higher leaf-to-water ratio than in Western-style brewing. Today, the approach is used popularly by teashops carrying tea of Chinese or Taiwanese origin, and by aficionados and trained masters as a way to fully realize the taste of a tea selection, especially a finer one.

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.

Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam".

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.

Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters — are water heaters that instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat exchanger coil unless the unit is equipped with an internal buffer tank. Copper heat exchangers are preferred in these units because of their high thermal conductivity and ease of fabrication. However, copper heat exchangers are more susceptible to scale buildup than stainless steel heat exchangers.
