An electric water boiler, also called a thermo pot or tea urnhttps://www.collinsdictionary.com/dictionary/english/tea-urn in British English, is a consumer electronics small appliance used for boiling water{{cite book|author=Max Cryer|title=The Godzone Dictionary: Of Favourite New Zealand Words and Phrases|url=https://books.google.com/books?id=XDSVbv4ZIpIC&pg=PA64|date=8 October 2010|publisher=ReadHowYouWant.com|isbn=978-1-4587-7952-6|access-date=2014-03-25|page=64}}{{cite book|author=Leon Reznik|title=Fuzzy Controllers Handbook: How to Design Them, How They Work|url=https://books.google.com/books?id=ar0-84SktfQC&pg=PA10|date=21 August 1997|publisher=Newnes|isbn=978-0-08-050716-3|access-date=2014-03-25|page=10}} 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, hot chocolate, coffee, 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.{{cite book|author=Matsushita Electric Corporation of America|title=Annual report|url=https://books.google.com/books?id=icuRAAAAIAAJ&q=%22thermo+pot%22|year=1992}}
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.{{Cite web |title=Electric Water Boiler Parts And What They Do |url=https://debeste.com/heetwaterdispenser/ |access-date=2024-03-07 |website=DeBST}} 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|reason=that would mean that at high altitude the water boiler won't work (water boils there at 90°C) but that's not true. Also if you leave the lid open water is boiling but it not automatically shut off. In many devices there is a bimetal that measures the amount of steam.|date=September 2014}}
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 water boilers, descaling agents such as vinegar or citric acid are commonly used. These substances effectively dissolve and remove the accumulated minerals, restoring the boiler's performance and eliminating any associated odors.{{cite book|author=Christopher Goodall|title=How to Live a Low-Carbon Life: The Individual's Guide to Stopping Climate Change|url=https://books.google.com/books?id=S0Ai9p2_-xgC&pg=PA157|date=4 May 2012|publisher=Routledge|isbn=978-1-136-56406-2|page=157|access-date=2014-03-25}}
Uses
Some electric water boiler models enable tea to be steeped at a desired, adjustable temperature.{{cite web |title=The Tide in Tea - Features - Gourmet Retailer Magazine |url=http://www.gourmetretailer.com/article-the_tide_in_tea-7129.html |quote=As tea drinkers become increasingly sophisticated, so too do the equipment and brewing techniques for this aromatic beverage. A number of companies [offer] precision temperature control}}
