Beneath the scraper, a simple heat coil — that looks not unlike an immersion heater — quickly warms up the tool, helping you to break up and remove ice.

Perhaps the most storied of these devices is the sous vide, a glorified immersion heater that keeps water at a precise temperature in order to evenly cook foods, usually meats in vacuum-sealed bags.

Nor are domestic supplies always up to the strains of, say, an 11kW charger; using the kettle or immersion heater during the six hours it would take to charge up a 90kWh battery could blow the fuses.

Small domestic immersion heater, 500 W An immersion heater has an electrical resistance heating element encased in a tube and directly placed in the water (or other fluid) to be heated. Portable immersion heaters may not have a control thermostat, since they are intended to be used only briefly and under control of an operator. For domestic hot water supply, or industrial process hot water, permanently installed heating elements in an insulated hot water tank may be used, controlled by a thermostat to regulate temperature. Household units may be rated only a few kilowatts.

Industrial water heaters may reach 2000 kilowatts. Where off-peak electric power rates are available, hot water may be stored to use when required. Electric shower and tankless heaters also use an immersion heater (shielded or naked) that is turned on with the flow of water. A group of separate heaters can be switched to offer different heating levels.

In British electric locomotives the steam generator was usually an electric steam boiler, heated by a large electric immersion heater running at the (then) line voltages of 600 volts from a third rail or 1,500 volts from an overhead wire. The Polish electric locomotive EL204 of 1937 was fitted with an electric steam generator supplied from overhead lines. The locomotive was destroyed during the second world war.

Exhaust air heat pumps have minimum flow rates that when installed in a small flat the air flow chronically over ventilates the flat increasing the heat los by drawing in large amounts of unwanted outside air. For most exhaust air heat pumps there will be a low heat output to the hot water and heating of just around 1.2 Kw from the compressor / heat pump process but if that falls short of the building's requirements additional heat will be automatically triggered in the form of immersion heaters or an external gas boiler. The immersion heater top up will be substantial and when a unit with a 6 kW immersion heater operates at full output it will cost £1 per hour to run. A newer version from Nibe Sweden the F730 takes in additional air from outdoors to the above process - this is a more powerful type of EAHP with an inverter controlled compressor.

The TLn coil immersion heater was initially manufactured by 10 employees working in two leased buildings at Reichenberger Strasse 143 and Oppelner Strasse 34 in Berlin. On 3 March 1925, production was moved to the third floor of Reichenberger Strasse 160. Initially, only immersion heaters under the "Eltro" brand were manufactured here, with an annual output of up to 60,000 units. In 1927, the company had 26 employees and generated an annual turnover of 184,745 Reichsmark.

Underground distribution systems connect all the users to the supply, with individual current limits to each facility. ECAMI installs PV supply systems for mobile phone masts, with considerable savings in fuel diesel. In Managua, the capital of Nicaragua, six hotels have been supplied with solar water heating systems by ECAMI. One with 50 m2 of panel area supplies 100 rooms each of which had previously required a 6 kW immersion heater, another with 16 m2 of panels supplies 40 rooms.

The ventilation air stream is around 31 litres per second and the heat of recovery is 750W and no more. All additional heat necessary to provide heating and hot water is from electricity, either compressor electrical input or immersion heater. At outside temperatures below 0 C this type of heat pump removes more heat from a home than it supplies. Over a year around 60% of the energy input to a property with and exhaust air heat pump will be from electricity.

The liquid is kept heated by an immersion heater at about , which causes it to slowly evaporate and condense on the inner walls of the outer vessel. The condensation that accumulates in the bottom of the vessel can then be diverted directly down through a filter containing activated carbon. The final product has approximately twice as much alcohol content as the starting liquid and can be distilled several times if stronger distillate is desired. The method is slow, and is not suitable for large-scale production.

In North America, these vessels are called hot water tanks, and may incorporate an electrical resistance heater, a heat pump, or a gas or oil burner that heats water directly. Where hot-water space heating boilers are installed, domestic hot water cylinders are usually heated indirectly by primary water from the boiler, or by an electric immersion heater (often as backup to the boiler). In the UK these vessels are called indirect cylinders, or direct cylinders, respectively. Additionally, if these cylinders form part of a sealed system, providing mains-pressure hot water, they are known as unvented cylinders.

An airing cupboard is a built-in storage space, sometimes of walk-in dimensions, containing a water heater, either an immersion heater for hot running water or a boiler for central heating water (hence, also "boiler cupboard"), or a hot water storage tank. Shelves, usually slatted to allow for circulation of heat, are positioned above or around the heater to provide room for clothing. The purpose is to allow air to circulate around the stored fabrics to prevent damp forming. Some variants of airing cupboards also serve as the linen cupboard, the storing area of the household's clean sheets and towels.

The aluminium- bodied cars – steel supplies were effectively non-existent for new businesses in Britain's new centrally planned economy – were extremely complex and very expensive with a torque converter (Brockhouse Hydro-Kinetic Turbo Transmitter) entirely replacing the gearbox. The torque converter was controlled by a small switch with forward and reverse positions. Suspension was fully independent using torsion bars and there were built-in electric jacks. Other innovative luxury items included a trickle-charger to charge the battery from the domestic mains, an immersion heater in the engine, interior heating of the body and a built-in radio.

At high combustion efficiencies a drain must be supplied to handle the water condensed out of the combustion products, which are primarily carbon dioxide and water vapor. In traditional plumbing in the UK, the space-heating boiler is set up to heat a separate hot water cylinder or water heater for potable hot water. Such water heaters are often fitted with an auxiliary electrical immersion heater for use if the boiler is out of action for a time. Heat from the space-heating boiler is transferred to the water heater vessel/container by means of a heat exchanger, and the boiler operates at a higher temperature than the potable hot water supply.

A variety of SiAlON phosphor powders under UV light SiAlON ceramics have found extensive use in non-ferrous molten metal handling, particularly aluminium and its alloys, including metal feed tubes for aluminum die casting, burner and immersion heater tubes, injector and degassing for nonferrous metals, thermocouple protection tubes, crucibles and ladles. In metal forming, SiAlON is used as a cutting tool for machining chill cast iron and as brazing and welding fixtures and pins, particularly for resistance welding. Other applications include in the chemical and process industries and the oil and gas industries, due to sialons excellent chemical stability and corrosion resistance and wear resistance properties. Some rare-earth activated SiAlONs are photoluminescent and can serve as phosphors.

Dr Theodor Stiebel founded the "ELTRON Dr. Theodor Stiebel" company at Reichenberger Strasse 143 in Berlin's Kreuzberg district with a base capital of 20,000 Reichsmark on 5 May 1924. According to the Commercial Register, the company began operating on the very same day. Dr Stiebel was loaned the capital for this by his uncles, Hermann Stiebel, who ran a hotel in Hamburg and Carl Reese who owned a metalworking business (canning factory) in Holzminden. With his patented invention of the first coil immersion heater, marvelled at by visitors to the 1924 Spring Trade Fair in Leipzig due to its rapid heat-up time and short cooling period, Dr Stiebel laid the foundations for the large-scale production that would begin one year later.

Unitized Group Ration (UGR) being heated in hot water immersion heater before serving B ration (or Type B Ration) is a term used in the United States military for a meal provided to troops which was prepared using canned or preserved ingredients. 'B' ration meals may be prepared in field kitchens and served in the field, or served in garrisons without adequate refrigeration or freezer facilities. 'B' rations differ from 'A' rations in that they do not use fresh, frozen, or refrigerated ingredients. They are distinguished from field rations, formerly known as C rations (such as the Meal, Ready-to-Eat or its predecessor, the Meal, Combat, Individual ration) in that they are ordinarily prepared in field kitchens instead of being distributed at the unit or individual level for immediate consumption.
